Diamond Colour is one of the 4c’s used to calculated diamond value
Polished diamond prices are derived from a variety of factors, including supply and demand, the quality and characteristics of the individual diamond, and market conditions.
The prices of polished diamonds are primarily determined by the 4Cs: carat weight, colour, clarity, and cut. These factors are assessed by gemologists and other experts who evaluate the diamond’s physical properties, such as its size, colour, clarity, and overall quality of cut.
Other factors that may influence the price of polished diamonds include the type of diamond, such as whether it is a natural or lab-grown diamond, the country of origin, and the overall market conditions for diamonds. Additionally, the reputation and credibility of the seller or the dealer can also affect the price of the polished diamond.
Overall, polished diamond prices are determined by a complex combination of factors, and can fluctuate over time based on changes in supply and demand, market conditions, and other economic and industry factors. There is no single diamond price list that accurately reflects the prices of all diamonds. This is because the price of a diamond depends on a number of factors, including its size, shape, colour, clarity, and other characteristics.
That being said, there are various industry-standard diamond price lists that are commonly used as references by professionals in the diamond trade. These lists are typically based on a standardized grading system and provide price ranges for diamonds of different sizes, shapes, and quality grades.
The most commonly used diamond price list is the Rapaport Diamond Report, which provides a benchmark price for diamonds based on their 4Cs grading (carat weight, colour, clarity, and cut). However, it is important to note that the Rapaport price list only reflects the wholesale price of diamonds and may not necessarily reflect the retail price that consumers will pay.
Other diamond price lists include the International Diamond Exchange Price List, the Idex Diamond Price Report, and the Polished Prices Diamond Index, among others. These price lists may differ in their methodologies and grading systems, and the prices they list may vary slightly from one another.
Ultimately, when buying or selling a diamond, it is important to work with a reputable and knowledgeable diamond professional who can help you evaluate the diamond’s characteristics and provide you with an accurate price estimate based on current market conditions. Source: Michael Cohen DCLA
Diamond traceability refers to the ability to track the journey of a diamond from its source to the market. This includes tracing the diamond’s origin, the path it takes through the supply chain, and the ultimate destination where it is sold to consumers.
Diamond traceability is important for a number of reasons. For one, it can help ensure the ethical and sustainable sourcing of diamonds, by allowing for greater transparency and accountability in the supply chain. This can help prevent the trade of conflict diamonds, which are used to finance armed conflict and human rights abuses. Additionally, diamond traceability can help provide assurance to consumers that the diamonds they purchase are of high quality and have been sourced responsibly.
The diamond industry has established various initiatives to promote diamond traceability, including the Kimberley Process Certification Scheme, which aims to prevent the trade of conflict diamonds, and the Responsible Jewellery Council, which sets standards for responsible sourcing practices in the industry. Additionally, some diamond producers have implemented blockchain technology to enable the secure tracking of diamonds throughout the supply chain.
Certification is another key aspect of diamond traceability. By obtaining a diamond certificate, which includes a record of the diamond’s characteristics and its journey through the supply chain, consumers can be assured that the diamond they are purchasing is of high quality and has been sourced responsibly. Overall, diamond traceability is an important aspect of the diamond industry, as it can help promote responsible sourcing practices and provide assurance to consumers about the quality and authenticity of the diamonds they purchase.
While it may not be possible for an individual to physically track a diamond from the source, certification and other industry initiatives can help ensure the ethical and sustainable sourcing of diamonds, as well as provide assurance to consumers about the quality and authenticity of the diamonds they purchase.
One technique used to determine the origin of diamonds is through the analysis of their chemical composition. Diamonds from different geographic locations can have different trace elements and isotopic compositions, which can be used to identify their origin. For example, diamonds from different mines in South Africa can have different isotopic signatures.
Another method to determine the origin of a diamond is through the use of spectroscopy, which involves analyzing the unique spectral characteristics of a diamond. This can provide clues about its origin and the geological conditions under which it formed.
It’s worth noting that while these techniques can provide clues about a diamond’s origin, they are not foolproof and may not provide a definitive answer in every case. Nonetheless, advances in technology and the diamond industry’s commitment to responsible sourcing have made it increasingly possible to track and trace diamonds from their source.
Conflict diamonds, also known as blood diamonds, are diamonds that have been mined in war zones and sold to finance armed conflict against governments. These diamonds are typically mined under inhumane conditions by workers who are often forced to work in dangerous and exploitative conditions. The profits from the sale of these diamonds are then used to fund armed conflicts, which often involve violence, human rights abuses, and forced labor. This cycle of violence and exploitation is known as the “diamond curse.” To combat the trade in conflict diamonds, the international community has established the Kimberley Process Certification Scheme, which requires that all rough diamonds be certified as conflict-free before they can be sold on the international market. The Kimberley Process has helped to significantly reduce the trade in conflict diamonds, but concerns remain about the effectiveness of the scheme and the ongoing trade in illicit diamonds.
What percentage of diamond production are conflict diamonds The percentage of diamond production that can be considered conflict or blood diamonds has decreased significantly since the introduction of the Kimberley Process Certification Scheme in 2003. According to the Kimberley Process, the percentage of conflict diamonds in the global diamond trade has fallen from approximately 15% in the 1990s to less than 1% today. However, it is important to note that some critics have raised concerns about the effectiveness of the Kimberley Process in preventing the trade in conflict diamonds. They argue that the definition of conflict diamonds used by the Kimberley Process is too narrow, and that some diamonds mined in areas of conflict may still be entering the market through illegal channels. Furthermore, there have been reports of human rights abuses and unethical practices in diamond mining in countries that are not considered conflict zones. So while the percentage of conflict diamonds in the global diamond trade is believed to be low, it is important to remain vigilant and continue efforts to ensure that all diamonds are mined and traded ethically and responsibly.
How do i ensure the diamond i buy is conflict free To ensure that the diamond you buy is conflict-free, you should look for a diamond that has been certified as such by a reputable organization. The most widely recognized certification scheme for conflict-free diamonds is the Kimberley Process Certification Scheme (KPCS), which was established in 2003 to prevent the trade in conflict diamonds. Here are some steps you can take to ensure that the diamond you buy is conflict-free:
Buy from a reputable jeweller: Look for a jeweller that is committed to selling conflict-free diamonds and has a policy in place to verify the origin of their diamonds. Many jewelers are members of organizations that promote ethical and responsible diamond sourcing, such as the Responsible Jewellery Council or the Jewelers of America.
Ask for a certificate of authenticity: Ask your jeweller for a certificate of authenticity that verifies the origin of the diamond you are interested in buying. The certificate should state that the diamond is conflict-free and has been mined and traded in compliance with the Kimberley Process.
Look for laser inscriptions: Some diamonds may have a laser inscription on the girdle that indicates the origin of the diamond and its certification number. This can be a helpful way to verify the diamond’s origin and ensure that it is conflict-free.
Consider buying a lab-grown diamond: Lab-grown diamonds are an ethical and sustainable alternative to mined diamonds. They are produced in a laboratory using advanced technology and do not have the same environmental or social impacts as mined diamonds.
By taking these steps, you can help ensure that the diamond you buy is conflict-free and has been mined and traded in a responsible and ethical manner.
Argyle pink diamonds are extremely rare and highly sought-after, making them some of the most valuable diamonds in the world. The Argyle diamond mine in Western Australia is the primary source of pink diamonds, and it is estimated that only 0.01% of the diamonds recovered from the mine are pink in colour, with an even smaller percentage being of the highest quality.
The Argyle mine ceased operations in 2020, which has led to speculation that the prices of pink diamonds, including argyle pink diamonds, may increase in the coming years. With the mine no longer producing new stones, the limited supply of these rare diamonds is expected to drive up demand and prices. However, like any investment, it’s important to carefully consider market trends and consult with a qualified professional before making any decisions.
The largest pink argyle diamond found to date is the Argyle Pink Jubilee, which was discovered at the Argyle mine in Western Australia in 2011. The diamond weighs 12.76 carats and is a vivid pink colour, making it one of the largest and most valuable pink diamonds ever found. The Pink Jubilee was cut and polished over a period of ten months, during which time the rough diamond was studied and analyzed extensively to determine the best way to bring out its natural beauty and maximize its value. The diamond was sold at auction in 2013 for an undisclosed sum, but it is believed to have fetched a record-breaking price per carat for a pink diamond.
Red diamonds are extremely rare, even more so than pink diamonds. It is estimated that only a handful of natural red diamonds are found each year, and most of them are less than half a carat in size. Red diamonds are so rare that many jewelers and gemologists may go their entire careers without ever seeing one.
The red colour in diamonds is caused by the presence of a rare mineral which causes “graining,”, This occurs when the crystal structure of the diamond is distorted during its formation. The graining causes the diamond to absorb green light and reflect red light, resulting in a beautiful and distinctive red hue. Because of their rarity, red diamonds are among the most valuable and expensive gemstones in the world. They are highly sought-after by collectors and investors, and prices for top-quality stones can reach millions of dollars per carat at auction.
Blue diamonds are also quite rare, but not as rare as pink or red diamonds. Blue diamonds account for only about 0.02% of all diamonds mined worldwide. The blue colour in diamonds is caused by the presence of trace amounts of boron during their formation, which causes the diamond to absorb red, yellow, and green light, resulting in a blue hue.
Blue diamonds are highly prized for their unique colour and rarity, and they can command very high prices at auction. The value of a blue diamond depends on a variety of factors, including its size, colour intensity, clarity, and overall quality. Blue diamonds range in colour from pale blue to vivid blue, with the most valuable stones being those with a deep, rich blue colour.
One of the most famous blue diamonds is the Hope Diamond, which is a 45.52-carat blue diamond that is part of the Smithsonian Institution’s collection of natural history specimens.
The most expensive diamond ever sold is the Pink Star, a 59.60-carat oval-cut pink diamond that was sold for $71.2 million at a Sotheby’s auction in Hong Kong in 2017. The diamond, which is the largest internally flawless fancy vivid pink diamond ever graded by the Gemological Institute of America (GIA), was mined in Africa in 1999 and took two years to cut and polish.
The Pink Star was originally sold at auction in 2013 for a record-breaking $83 million, but the sale was later cancelled after the buyer defaulted on the payment. The diamond was put back up for auction in 2017 and sold to a jewelry retailer in Hong Kong for $71.2 million, setting a new world record for the most expensive diamond ever sold at auction.
Yellow diamonds are not as rare as pink, red, or blue diamonds, but they are still considered rare and highly prized. Yellow diamonds are formed when nitrogen atoms are trapped in the crystal lattice structure of the diamond during its formation, causing it to absorb blue light and reflect yellow light.
The intensity of the yellow colour in a diamond can vary widely, ranging from a pale yellow or light lemon colour to a deep, intense yellow. The most valuable yellow diamonds are those with a deep, rich colour that is evenly distributed throughout the stone.
Yellow diamonds are mined in various parts of the world, including South Africa, Australia, and Canada. While yellow diamonds are not as rare as some other coloured diamonds, high-quality yellow diamonds can still command very high prices at auction, especially those with a large carat weight and intense colour.
Orange diamonds are considered rare and highly valuable. The orange colour in diamonds is caused by the presence of nitrogen and other impurities in the crystal lattice structure of the diamond, which absorb blue and green light, resulting in an orange hue.
Orange diamonds can range in colour from pale orange to a deep, vivid orange, with the most valuable stones being those with a pure and intense colour. Orange diamonds are not as commonly found as white or yellow diamonds and are considered much rarer than brown or gray diamonds.
The most famous orange diamond is the Pumpkin Diamond, a 5.54-carat fancy vivid orange diamond that was mined in South Africa. The Pumpkin Diamond was sold at auction in 1997 for over $1.3 million, and it is now part of the collection at the Smithsonian Institution’s National Museum of Natural History in Washington, D.C.
De Beers has increased prices of small rough diamonds for the second consecutive sight as a combination of demand and supply factors continue to create a hot market for the category.
Prices for tiny stones rose by around 10% on average at this week’s trading session, with sharper advances in certain segments, customers and insiders estimated Monday. The changes were mainly for minus-7 sieve sizes, which weigh about 0.03 carats, across a range of qualities. De Beers was unavailable for comment.
The February sale runs this week from Monday to Friday in Gaborone, Botswana.
Rough under 0.75 carats became a sought-after asset in the second half of 2022 as melee demand from luxury brands strengthened and Indian manufacturers needed cheaper material to fill factories amid thin profit margins. In addition, Western sanctions on Russian diamonds created a mixture of real and perceived shortages in those sizes, for which Alrosa is the biggest supplier. The trade is watching for potential further restrictions as the one-year anniversary of Russia’s invasion of Ukraine approaches.
“Are people preempting what the [new] measures might be on Russia? [The strong market] might have to do with that,” a rough-market participant told Rapaport News on condition of anonymity.
Last year, De Beers made only modest increases in the prices of smalls, even when the segment saw robust demand, a sightholder explained on condition of anonymity. The miner raised prices at last month’s sight by approximately 10% — alongside decreases in the slower, larger goods.
The fresh hikes caught many dealers by surprise, as they were expecting De Beers to monitor the Chinese recovery before making further price adjustments.
Botswana’s President Mokgweetsi Masisi warned Sunday that his country could sever ties with South African diamond giant De Beers if talks to renegotiate a sales agreement prove unfavorable for his country.
The 2011 sales agreement governing the terms of marketing diamonds produced by Debswana – a 50-50 joint venture between the government and De Beers – expired in 2021.
It has been extended by the parties, who cited the coronavirus outbreak as the reason for the delay in concluding negotiations, and will end on June 30, 2023.
Speaking at a rally of his ruling Botswana Democratic Party (BDP) in his home village of Moshupa, about 65 kilometers from the capital Gaborone, Masisi warned, “If we don’t reach a win-win situation, each side will have to pack up and go home.”
Under the 2011 agreement, the mining company De Beers received 90% of the rough diamonds produced while Botswana, Africa’s largest diamond producer, received 10%. In 2020, Botswana’s share was increased to 25%.
In 2020, Botswana’s share was increased to 25%.
Today, “we got a glimpse of how the diamond market works, and we found out that we received less than we should have,” said Mr. Masisi, who spoke in both English and the local language, Tswana.
“We also found out that our diamonds are bringing in a lot of profit and that the (2011) agreement had not been favorable to us,” he added, before warning: “We want a bigger share of our diamonds. Business cannot continue as before.
A new list names the Jwaneng diamond mine, in Botswana, as the world’s richest diamond mine.
A new list by miningintelligence.com, quoted by IDEX Online, names the Jwaneng diamond mine, in Botswana, as the world’s richest diamond mine for the first three quarters of 2022. Jwaneng produced 10.3 million carats in 2022.
Orapa, also in Botswana, came second with 8 million carats. Both Jwaneng and Orapa are operated by Debswana, a partnership between De Beers and the government of Botswana. Jwaneng and Orapa were also listed as the two highest value diamond mines in the world, estimated at $1.25 billion and $976 million respectively, “based on average historic annualized prices of $121.5 per carat,” according to the report.
Alrrosa’s Udachny mine came third. Although Alrosa has not published production figures since the war with Ukraine, miningintelligence.com bases its conclusion on the mine’s 2021 production of 4.6 million carats. Fourth comes the Venetia mine in South Africa 4.6m carats, operated by De Beers. In fifth is Nyurba, in Russia, with 3.6 million carats, based on 2021 numbers.
The Bank of Tanzania announced that the country’s diamond exports increased significantly to $63.1 million (USD) in value by November 2022. This is more than seven times of the $8.4 million export value that was recorded in the year-over year analysis since November 2021.
The good performance of the company has been attributed to the country’s diamond producer Williamson Mines which has temporarily shut down operations due to a recent tailings breach on November 7, 2022. The mine is an open pit operation located on the 146-hectare Mwadui kimberlite pipe, which is one of the world’s largest economic kimberlites.
The company belongs to the parent company Petra Diamonds, which owns 75 percent of the company, and the Tanzanian government owns the remainder. According to Petra’s official statement, production at the Williamson mine will resume in the 2024 fiscal year.
De Beers has made sharp price changes at this week’s sight, implementing deep reductions in larger goods and increases for smaller stones.
Prices fell by as much as 10% in 2-carat rough and above, with lower-quality items seeing the most significant drops, sources told Rapaport News Monday on condition of anonymity. Prices of diamonds under 0.75 carats rose by similar percentages, reflecting a market split that has persisted since late last year, insiders said. Sizes in between saw more modest declines.
“There have been quite wild increases and decreases,” one source said. “Not to say that they’re not justified, but it’s interesting that they’ve done that.”
De Beers declined to comment.
The adjustments follow months of sluggishness in larger, lower-quality rough as Chinese demand slumped during the country’s Covid-19 outbreaks and inflation dented mid-market US spending. Stones in the 3-grainer category and below have remained relatively strong due to steady sales of polished melee and Indian manufacturers’ efforts to fill factories with cheaper material.
De Beers kept its prices firm throughout 2022 despite the weakness in the larger categories, which constitute a significant proportion of its sales. This impacted profit margins at cutting firms, many of which perceived the miner’s rough to be expensive, insiders explained.
“These are the prices [at] which they should have been selling since October,” a sightholder commented. “It’s aligning with reality [rather than] reflecting a relatively poor end of year.”
De Beers is known for its reluctance to reduce prices during downturns, as was the case during the Covid-19 crisis. Now, as then, it has waited for a slight improvement in trading before taking action. China’s reopening has boosted sentiment, while the recent US holiday period was satisfactory, albeit slower than 2021’s record season.
The first sight of 2023, which runs Monday to Friday, comes amid uncertainty about the global economic situation, the Russia-Ukraine crisis, and the prospects for the Chinese New Year, which occurs on January 22.
It’s also a time of transition at De Beers, which is welcoming a new CEO, Al Cook, to succeed Bruce Cleaver on February 20 and is in the middle of negotiations with the Botswana government over an updated sales deal.
“Generally, things are a bit better than they were four or five months back, but that is because of low [polished] production, not because of an improvement of the market,” a manufacturing executive commented. “So the challenges remain.”
Sarine Technologies has agreed to acquire a majority share in New York-based Gem Certification and Assurance Lab (GCAL) amid a push to expand in the American market.
“At the beginning of last year, we started ramping up our activities in the US,” Sarine CEO David Block told Rapaport News on Thursday. “Due to that, the discussions with regard to this [deal] ramped up along with our involvement in the US market. This [deal] should be quite a significant jump in the scope of our business in the US.”
Israel-based Sarine has signed a nonbinding memorandum of understanding (MoU) to purchase the stake for an all-cash consideration, it announced in a statement on Wednesday. The parties plan to reach a final agreement in a few months once due diligence is complete, Block said. The companies have not disclosed the sale price or the size of the share.
GCAL will continue to offer its customers the same products and services as before the deal, and its executives will remain in charge, Sarine said.
However, while currently operating out of a single location in New York, GCAL will be able to implement Sarine’s e-Grading — an automated grading service using artificial intelligence (AI) — to develop the lab’s capabilities across the US and globally. The companies will begin integrating their technology and services even before the deal closes, Block explained. Sarine will continue to offer its services independently outside the US.
Founded in 2001 by Don Palmieri, family-owned GCAL is known for providing diamond certificates carrying a guarantee, rather than just reports that act as a description of grades. In 2021, it launched 8X, a cut-grading standard that it claims is more exacting than the industry’s triple Ex score.
“Sarine’s technologies will allow us to continue to abide by [our] key code of ethics while still expanding our services to meet the growing demand by consumers seeking confidence that their acquired products and services meet all norms of quality and sustainability,” said GCAL chief operating officer Angelo Palmieri.
