WDC WELCOMES TWO NEW MEMBERS
The World Diamond Council is proud to enter into its ranks two new members – each committed to protecting the integrity of the diamond supply chain. They are eValuer and Yoshfe Diamonds International (YDI).
JUNE 18, 2026
eVALUER
eValuer is a groundbreaking online rough diamond valuation platform delivering unparalleled accuracy and transparency in diamond pricing. By harvesting data from rough sales across major tender and auction houses in Dubai, Antwerp, South Africa, Botswana, Angola and India, it analyzes hundreds of millions of dollars in transactions to produce a monthly price book spanning 3,566 diamond categories. Trusted to value approximately $2 billion of diamonds annually, eValuer is used across most major diamond-producing and processing countries worldwide.
eValuer operates independently, ensuring unbiased valuations underpinned by over 20 years of industry expertise. Its tools provide equal access to real-time, data-driven market pricing based entirely on actual sales — not estimation — enabling informed decision-making for producers, manufacturers, and buyers alike.
eValuer serves government diamond valuation teams in South Africa, Angola, United Arab Emirates, Zimbabwe, Sierra Leone, Liberia, Botswana and the United Kingdom, as well as the Kimberley Process Certification Scheme’s Working Group of Diamond Experts.
While eValuer is intuitive enough for experienced professionals to use without training, tailored programs are available at clients’ own premises. All users have access to a detailed online assortment guide, hands-on sessions with real assortments, and ongoing quality control support to ensure continuous improvement.

YOSHFE DIAMONDS INTERNATIONAL (YDI)
Yoshfe Diamonds International (YDI) is a fourth-generation family business with a longstanding presence in the diamond industry, which was founded in 1946 by the late Zorach Fluk, a pioneering member of the Israeli diamond industry.
Today, the company is a prominent diamond manufacturer and supplier, led by Chairman Abraham Fluk, CEO Ori Fluk, and Sarah Fluk-Gross, who heads the jewelry retail division. While deeply rooted in tradition, YDI continuously embraces innovation and integrates advanced technologies and modern practices into its operations.
With offices in Tel Aviv, New York, Antwerp, and Hong Kong, YDI manufactures natural diamonds through its manufacturing operations and is recognized for its advanced sorting expertise. Its inventory includes more 1,700 narrowly defined categories, each identified by a simple Sortified™ Key Code, enabling clients to source exactly the diamond they want with efficiency and precision.
YDI maintains responsible and ethical sourcing practices throughout its supply chain and full traceability of its diamonds to origin, including melee stones. The company places strong emphasis on sustainability, environmental responsibility, and social responsibility as integral parts of its operations.
YDI is a proud member of the Responsible Jewellery Council (RJC), the WJ Initiative 2030 (WJI 2030), and now also of the World Diamond Council (WDC).
