Fancy Vivid Yellow Rough Diamond

Rethink Yellow Diamond Jewels: How Yellow Diamonds Get Their Colour

Yellow diamonds are making a stylish comeback. Whether offering a warm, earthy glow or a vibrant pop of colour, these fancy-coloured stones bring a fresh, contemporary edge to fine jewellery. They can be worn as neutrals, used as centrepieces, or layered for subtle impact—making them as versatile as they are striking.

The colour in yellow diamonds is the result of nitrogen atoms bonding with carbon within the diamond’s crystal lattice. This bond subtly alters the diamond’s atomic structure, changing the way it interacts with light. Specifically, it absorbs the blue part of the visible spectrum, allowing yellow tones to dominate. The Diamond Certification Laboratory of Australia (DCLA) grades yellow diamonds based on their colour intensity, classifying them as light, intense or vivid. The deeper and more saturated the yellow, the rarer and more valuable the diamond. Curiously, the lighter tones are often more affordable than white diamonds, making them an attractive alternative for those seeking something both elegant and unique.

Why Designers Are Embracing Yellow Diamonds

Jewellery designers are increasingly drawn to yellow diamonds for their warmth, individuality, and unexpected elegance. These stones challenge the norm, offering something joyful and radiant while still being refined. As the jewellery world moves beyond the conventional, yellow diamonds are gaining traction as centrepieces with personality.

How to Wear Yellow Diamonds

Once your collection includes the classics such as white diamond hoop earrings, tennis bracelets, stacking rings or a line necklace it’s easy to introduce a splash of colour. Yellow diamonds pair beautifully with white or rose gold and work well layered with other tones. Go bold with vibrant yellow bangles and cocktail rings, or opt for a more understated approach with a mix of pale-yellow and Champagne diamonds, as seen in Sethi’s neutral-toned confetti styles.

Yellow Diamonds: The Emerging Trend in Engagement Rings

More couples are seeking engagement rings that reflect their personal style rather than adhering to tradition. Yellow diamonds especially those in softer or more earthy tones offer a refined, alternative aesthetic that still feels timeless and romantic.

One designer, Root, recalled a client who brought him a family heirloom: a pear-shaped yellow diamond. He combined it with a matching white diamond to form a heart-shaped engagement ring. Initially, clients were hesitant about yellow diamonds, unsure whether they carried the same prestige. That perception is changing rapidly.

Designer Lau echoes this sentiment. “As our view of what defines a high-quality diamond evolves, I find myself drawn to warmer tones and even imperfect shapes, they feel authentic and special,” she explains. Yellow diamonds are increasingly favoured for their character, individuality, and natural charm.

Why Yellow Diamonds Are Here to Stay

There’s an undeniable joy and brightness that yellow diamonds bring. Whether in soft pastel shades or vivid canary tones, they evoke a feeling of sunshine and optimism, something many people are seeking in their jewellery today.

As the desire for unique and meaningful designs continues to grow, yellow diamond engagement rings are well-positioned to become the next generation’s classic. After all, who can resist a jewel that radiates light, joy, and a touch of the unexpected?

“Most Coveted” A 16.9 ct Fancy Vivid Yellow Diamond

A flawless 16.92 carat vivid yellow diamond was unveiled last week at Jewellery & Gem World Hong Kong.

Mumbai based Venus Jewel says the radiant shaped natural diamond is one of the “most coveted diamonds” it has released in its 55 year history.

It was cut from a 28.78 carat rough stone. Natural vivid yellow colored diamonds are extremely rare. One out of approximately 10,000 carats mined is a natural fancy color diamond. Of those only a small percentage are fancy vivid, the highest grading for color saturation and brilliance.

Fancy Color Diamond Prices: First Drop in Almost Four Years

Fancy yellow diamond — Fancy yellow cushion cut diamond

The Index tracking fancy color diamond prices fell during the last quarter, for the first time in almost four years.

The Fancy Color Diamond Index, which monitors pricing data for of all sizes and intensities of fancy color diamonds, fell by 0.7 per cent during Q2 2024, according to an update published yesterday (30 July) by the Fancy Color Research Foundation (FCRF).

The last recorded fall was back in Q3 2020 – in the depths of the Covid crisis – when the Index also fell by 0.7 per cent. That came after two quarters when sales were too slow for the FCRF to produce figures at all.

The trend over the last year or so has been of slower growth. The Index was up 1.3 per cent in Q1 2023, followed by +0.5 per cent (Q2); +0.4 per cent (Q3); +0.1 per cent (Q4) and +0.1 per cent (Q1 2024).

The New York-based FCRF played down the Q2 dip, describing it as “a minor fluctuation when compared to broader market movements”.

It said in a statement: “This stability is particularly evident relative to the sharper declines in the white diamond market and the Dow Jones index, which fell by 3.6 per cent and 1.7 per cent respectively during the same period.

Yellow diamonds (all sizes, all intensities) suffered the biggest drop, down 1.7 per cent. Pinks and blues were both down 0.3 per cent.

The FCRF said its Index had enjoyed an overall increase of 211 per cent since it began compiling data in 2005. During that time it said the price of yellow diamonds had risen by 56 per cent, pinks by 398 per cent and blues by 248 per cent.

Slower Growth for Fancy Colour Diamond Prices

Fancy colour diamonds saw slower growth in the last three months, with an increase of just 0.5 per cent in the FCRF Index, which tracks prices across all colours, sizes and intensities.

That compares with a 1.3 per cent rise during the first quarter of 2023, as reported by the New York-based Fancy Colour Research Foundation, with the biggest increases among yellows.

During Q2, yellows diamonds again drove the increase, with a rise of 6.5 per cent across all categories. Pinks were up 0.2 per cent and blues rose by 0.6 per cent.

The FCRF noted that fancy colour diamonds had again out-performed white diamonds, which saw prices fall 3.5 per cent during the quarter.

Board member Eden Rachminov said: “The first six months of 2023 were intriguing. We experienced notable spikes in certain sub-categories within the yellow category, particularly in the intense and vivid grades with a high inner-grade.

“Meanwhile, the blue and pink categories remained stable. If the world economy continues to maintain its positive momentum, we can anticipate a robust price behavior after the summer.”

Fancy-Color Price Index Beats Expectations

Prices of fancy-color diamonds slipped marginally in the fourth quarter of 2020 as stability in the yellow category helped the sector stave off a heavier slump, according to the Fancy Color Research Foundation (FCRF).

“Although 2020 was challenging in terms of logistics and travel, contrary to market expectations, fancy-color diamond prices proved to be resilient, with minor price decreases across the board,” the FCRF said Monday.

The organization’s Fancy Color Diamond Index for yellows inched down 0.3% year on year in the three months ending December 31, while prices for blues fell 1.3%. Pink fancy-color diamonds decreased 0.9%, with the overall index slipping 0.8%.

The 1.50- and 5-carat categories were the strongest for fancy blues, increasing 0.5% versus the previous quarter, while fancy-vivid blues decreased 0.6%, led by soft prices for 1-carat stones in that category. Pinks stayed mainly flat compared to the third quarter, with 2-carat fancy pinks seeing the highest rise, up 1.4%. In yellows, the fancy-intense, 5-carat segment grew 0.8%, and the price for fancy-vivid, 3-carat stones was up 0.7%. Fancy-yellow, 1.50-carat diamonds increased 0.6% during the period.

The FCRF believes prices of yellows will continue to remain strong throughout 2021.

“2020 was a fascinating year; wholesalers and retailers alike had to overcome many logistical hurdles in order to finalize simple transactions, while demand for fancy-color diamonds was solid,” said FCRF advisory board member Eden Rachminov. “I expect 2021 to be a bullish year for yellows; their current price is relatively low and I think that a price increase is inevitable.”

Study yields new insight in hunt for rare, valuable yellow diamonds

Yellow diamonds, some with colourless cores

A new study by University of Alberta scientists could help guide the search for rare, high-value yellow diamonds in the Canadian North.

The researchers, led by PhD student Mei Yan Lai, examined the chemical makeup of stones recovered from the Chidliak and Ekati mines in Northern Canada to get a better understanding of how they formed.

“Without this research, we wouldn’t know that two separate formation events occurred, and that the second, more recent event is responsible for the yellow colour,” explained U of A diamond geologist Thomas Stachel.

“The more we know about the origin of these potentially high-value diamonds, the better results for diamond exploration and value creation in Northern Canada.”

Lai said they wanted to understand the origin of the yellow colour in the diamonds from the two deposits.

“Canadian yellow diamonds have never been studied spectroscopically in detail. Our results suggest that the cause is the preservation of unstable single nitrogen atoms preserved inside the diamonds,” explained Lai, who conducted this research as part of her master’s studies in the Diamond Exploration Research Training School under the supervision of Stachel.

The research team determined that some yellow diamonds contain colourless cores, meaning that the yellow outer layers crystallized on top of clearer centres. Lai determined that the yellow diamonds crystallized no more than 30,000 years before the kimberlite eruptions that brought them up to Earth’s surface.

“Our analysis shows that the colourless cores in these yellow diamonds are about one billion years older,” Lai said. “In fact, the carbon isotope compositions and nitrogen concentrations of the colourless cores and yellow outer layers are significantly different, suggesting that they formed in at least two distinct events and involved different diamond-forming fluids.”

The researchers said discovering a potential new source of yellow diamonds in the Canadian North is economically significant, as the previous main source of high-quality yellow diamonds, the Ellendale Mine in Western Australia, was recently shut down.

The discovery of colourless cores in some of the yellow diamonds may also be of interest to the jewelry trade, said Lai.

“Occasionally, rough yellow diamonds lose their vibrant yellow colour after being cut and polished—probably because this kind of diamond has a thin layer of yellow overgrowth on top of the geologically older colourless core,” she said.

The project is a collaboration with Dominion Diamond Mines and Peregrine Diamonds Ltd. Part of the analyses were done at the Gemological Institute of America.

The research is supported by a bursary through DERTS, funded by the Natural Sciences and Engineering Research Council of Canada’s Collaborative Research and Training Experience program.

The study, “Yellow Diamonds With Colourless Cores—Evidence for Episodic Diamond Growth Beneath Chidliak and the Ekati Mine, Canada,” was published in Mineralogy and Petrology.

Ellendale revival on the horizon with increased diamond value

Gibb River Diamonds has completed a review of the mothballed Ellendale diamond mine in Western Australia that will help it edge closer to a proposed restart.

The independent appraisal, which was completed by which was completed by Independent Diamond Valuers International (IDVI) valued gems from the Ellendale 9 East Lobe at $US750 ($1120) per carat.

This price represents a 20 per cent increase since 2008, largely due to the high number of fancy yellow diamonds unearthed at the West Kimberley-based mine.

With these results, a mine revival is looking ominous for the site, which was closed in 2015.

Last December, Gibb River Diamonds accepted an offer from the Western Australian Government apply for new tenements at the site.

“This review is important as it helps Gibb River Diamonds to make commercial decisions regarding mine planning and development priorities at Ellendale,” the company stated.

“Previous operators had a contract to sell the fancy yellow component of their production to Laurelton Diamonds (the jeweller Tiffany & Co).

“It is uncertain if similar premium prices can be achieved with any future fancy yellow goods.

“However, there is a potential opportunity to capitalise in the uniqueness of these fancy yellow goods to sell above market prices.”

The independent appraisal showed a further 18 per cent increase at the Ellendale 9 deposit to $US559 per carat since 2008.

The Ellendale 4 deposit also experienced an increase in value to $US135 per carat, representing a 5 per cent rise in 12 years.

IDVI uncovered 16 per cent fancy yellow diamonds within the Ellendale East Lobe, compared with 9 per cent in the West Lobe.

Gibb River has affirmed that as this information is based on generic sales data, future sales results could “vary significantly” from those in the report, as no sales have occurred since 2015.
