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.”

The FCRF tracks pricing data for fancy colour diamonds in Hong Kong, New York, Geneva and Tel Aviv.

Antwerp Diamond Polishers Develop Device That Uses AI to Grade Colored Stones

Chroma Diamonds founded by Alexander Appels and Jan De Henau is a relatively new company in the Antwerp diamond district, which specializes in colored diamonds. Stymied by the relatively “subjective process of color grading”, the 2 have set out on a mission to develop a device that provides more objective measurements for the grading of colored stones.

The device will utilize AI gathering data points and becoming smarter with each new set of inputs. They believe with sufficient time the device would learn enough to be able to more accurately grade certain stones, especially in resolving cases where certain grading criteria place the value of diamond on the edge of a color category but not quite enough to satisfy it being classified in the next grade above.

“Customers come to us with high expectations. After all, the value of their diamond is determined by, among other things, the color and intensity of that color, and let it (partly) depend on the cut and the people in the grading office, we hear. Because it is they who assign the diamond an official color, and therefore also determine its value definitively,” explains Appels.

Though this idea is not new to the Diamond District the duo has taken things one step further receiving support from the innovation process of the City of Antwerp. They plan on using and testing the device in their own business first as proof-of-concept before taking it to the greater market.

Rare Orange-Red Diamond Appears at Auction

Heritage Auctions has unveiled a 1.21-carat, fancy-orangey-red diamond that will go under the hammer at its Fall Fine Jewelry Signature auction on September 29.

“This gem is one of only a few diamonds to display enough saturation and intensity to be graded as a true red,” said Jill Burgum, Heritage Auctions’ executive director of fine jewelry. “Adding to the allure, the cause of a red diamond’s color remains a mystery to scientists, making this stone even more of a marvel.”

The stone has a presale estimate of $100,000 to $150,000.

Other notable diamonds included in the sale are a 17.63-carat, fancy-intense-yellow diamond ring from the estate of Dallas philanthropist Mary Anne Sammons Cree, which is expected to fetch $300,000 to $400,000. More than 125 jewels from Cree’s collection are up for sale, with the proceeds going to the Communities Foundation of Texas as well as Dallas-area nonprofits.


Alrosa finds first large coloured diamond at new Yakutia mine

17.44 carat diamond found at the Verkhne-Munskoye deposit

Russia’s Alrosa, the world’s top diamond miner by output, has found a 17.4-carat bright yellow gem-quality precious rock at its new Verkhne-Munskoye deposit in Yakutia, which started operations in 2018.

The diamond, recovered in mid-February from the Zapolyarnaya kimberlite pipe, is the first large coloured stone found at the site, the company said.

Alrosa, which did not disclose the estimated value of the diamond, said it would be assessed and evaluated by its experts in coming days.

Diamond miners and traders have been hit hard in the past year by weak market conditions. These factors have taken a major toll on producers of small stones due to an oversupply in that segment.

De Beers reported Thursday its worst set of earnings since Anglo American (LON:AAL) acquired it in 2012.

The world’s No. 1 diamond miner by market cap said demand for rough diamonds from polishers and cutters was weak last year due to the impact of US-China trade tension and the closure of US retail outlets. Many companies in the so-called midstream are struggling to obtain financing, it said.

Alrosa believes the situation is about to change as it’s already seeing the first signs of stabilization in the sector.

Increasing demand for synthetic diamonds has also weighed on prices. Man-made diamonds require less investment than mining natural stones and can offer more attractive margins.

Industry consultant Bain & Co., however, believes that while glut that’s depressing the diamond market will probably be cleared early this year, it will take at least another 12 months for the market to fully recover.

“The industry’s first and strongest opportunity to rebalance and regain growth will be 2021,” said Bain in a report released in December, adding that supply could fall 8% that year.


Blue and Pink Diamonds Show Price Stability in Q3 2019


Prices of fancy color diamonds remained stable in the third quarter of 2019, according to the Fancy Color Diamond Index (FCDI) published by the Fancy Color Research Foundation.

The prices of pinks remained stable this quarter. The slight decrease of 0.1 percent overall was due to a 3 percent decrease in the 5 carat fancy pink category. However, all fancy vivid pinks rose by 0.4 percent, with 1 and 3 carat fancy vivid pinks increasing by 1.6 percent and 1.7 percent.

Blue diamond prices increased just 0.1 percent. The sharpest increase came the 1.5 carat fancy vivid blue category (2.1 percent). Over the past 12 months, the price of this category has appreciated by 10.6 percent. The sharpest drop during this quarter (-2.2 percent) was in the 1.5 carat fancy intense blue category.

The prices of yellow diamonds decreased 1.5 percent during Q3. The largest price decrease of 3.5 percent was in the 3 carat fancy vivid yellow category. Only 2 carat fancy intense yellow diamonds did not experience a fall in prices.
