Industry News: Fancy Yellow Prices Stable But Blues, Pinks Up; De Beers Tests Blockchain; More May 16, 2018 (0 comments)


Fancy Yellow Diamond Prices Stabilize, Blues Up In Q1 2018

New York, NY—Prices of fancy color diamonds showed stability in most categories in Q1 2018, although fancy blue diamond prices rose moderately. A 6.16-carat pear-shaped dark grey-blue diamond called the Farnese (left) sold for $6.7 million at Sotheby’s Geneva on Monday, beating its $5.3 million estimate by $1.4 million.

The Fancy Color Diamond Index (FCDI) indicated an overall rise of 0.1% in in the first quarter for fancy color diamonds across all sizes and saturations, while blues increased 1.0%, continuing its trend from last year. Unsurprisingly, the better qualities—fancy intense and fancy vivid blues—outperformed. Most notably, in Q1 2018 the two-carat vivid pink and blue diamonds showed the highest rate of appreciation in their respective color categories—also of note at the Sotheby’s sale, a 9.7-carat light purplish pink diamond ring soared past its pre-sale estimate of $702,000 to sell for $2.6 million.

On a slightly less stratospheric level, year on year, the Fancy Color Diamond Index increased by 0.1% overall, with blue prices up 5.0% and yellow and pink prices down by 1.7% and 0.6%, respectively. By contrast, the IDEX price index shows colorless diamond prices rose 1.6% in Q1 2018.

The Fancy Color Diamond Index is published by the non-profit Fancy Color Research Foundation (FCRF), and tracks pricing data for yellow, pink and blue fancy color diamonds in three key global trading centers – Hong Kong, New York and Tel Aviv. For a complete data analysis, please visit​.


De Beers Group Trial Successfully Uses Blockchain Technology To Track First Diamonds From Mine To Retail  

London, UK—De Beers Group on Monday announced that it has successfully tracked 100 high-value diamonds along the value chain during the pilot of its industry blockchain platform, marking the first time a diamond’s journey has been digitally tracked from mine to retail. 

Blockchain technology leaves an immutable and secure digital trail was created for a selection of rough diamonds mined by De Beers as they moved from the mine to cutter and polisher, then through to a retail jeweler. Five diamond manufacturers—Diacore, Diarough, KGK Group, Rosy Blue NV and Venus Jewel—are participating in the blockchain platform trial.

The platform, trademarked Tracr, is expected to launch later this year and will be open to the industry. When fully operational, Tracr will provide consumers with confidence that registered diamonds are natural and conflict-free, improve visibility and trust within the industry, and enhance efficiencies across the diamond value chain.

The five manufacturers have been working with De Beers during the development of Tracr, and have played an integral role in creating the first blockchain platform to span the entire diamond value chain. The manufacturers have significant experience in the processing of large stones, which is the initial focus of the pilot, as well as broad coverage across the midstream of the industry.

 Bruce Cleaver, De Beers Group CEO, said, “The Tracr project team has demonstrated that it can successfully track a diamond through the value chain, providing asset-traceability assurance in a way that was not possible before. This is a significant breakthrough made achievable by the close engagement of the pilot participants who share our commitment to industry progress and innovation. We look forward to sharing the platform with more partners in the coming months and capturing their insights before ultimately making this technology available to the broader industry.”

How Tracr works: As the diamonds travel along the value chain, a unique Global Diamond ID is automatically created on Tracr, which stores individual diamond attributes such as carat, color, and clarity through integration with the participants’ existing record-keeping systems. This allows Tracr to consolidate the data into an immutable digital trail for each physical diamond, assuring its provenance and traceability from rough to polished. Tracr verifies the uploaded data at each key milestone of a diamond’s journey, ensuring its accuracy and continuity, while enabling users to be in full control of what they share with other participants through the use of privacy controls.

Tracr also will be using stone images, planned-outcome images, and a diamond's physical properties to verify authenticity through data science and physical identification techniques. The pilot was announced in January, following months of research and industry consultation. De Beers is working with BCG Digital Ventures to build the platform and the underlying technology.

CIBJO Congress To Meet In Colombia In October

Milan, Italy—CIBJO, the World Jewellery Confederation, will hold its 2018 annual congress in Bogotá, Colombia, October 15-17, with pre-congress meetings beginning on October 13. 

The congress will be hosted by Fedesmeraldas, the National Federation of Emeralds of Colombia, which this year will be a celebrating the 20th anniversary of its founding. Immediately prior to the event, from October 12 to 14, Fedesmeraldas will also host the second edition of the World Emerald Symposium, which CIBJO Congress participants are encouraged to attend. 

The main venue for the CIBJO Congress will be the Grand Hyatt Bogotá, located in the heart of Ciudad Empresarial Sarmiento Angulo, the city's commercial district.

CIBJO Congresses are the venue for the annual meetings of CIBJO's sectoral commissions, where amendments can be introduced to the organization's definitive directories of international industry standards for diamonds, coloured stones, pearls, gem labs, precious metals and coral, known as the Blue Books. The Congress also is where the World Jewellery Confederation Education Foundation (WJCEF), relating to responsible and sustainable activities in the industry, and CIBJO's ongoing cooperation with the United Nations and its development programs, are reported upon.

"In so many respects, Colombia represents both the past and the future of our industry," said Gaetano Cavalieri, CIBJO President. "It has been associated with the very finest of gemstones for centuries, but from a business perspective has still only scratched the surface of its potential, with studies indicating that about 80 percent of its vast emerald reserves still remain under the ground. The country's government and gemstone industry are committed to a programme that involves formalising the status of its artisanal and smaller-scale miners, enabling them to access the international markets, and so realize our business community's potential of being a force for sustainable economic and social development. With the focus of the world jewellery industry on Colombia leading up to and during the CIBJO Congress, we are delighted to be able to partner with Fedesmeraldas in highlighting this process."

A dedicated CIBJO Congress 2018 website will be launched shortly.
