De Beers India MD Calls for Better Tech to Distinguish Synthetic and Natural Diamonds
De Beers India managing director Amit Pratihari expressed concerns over the lack of transparency in synthetic diamond sales, emphasizing the importance of clear disclosure to consumers. He highlighted the need for proper certification and reliable grading institutions to distinguish natural diamonds from lab-grown ones, adding that the company’s in-house lab, which used to serve only De Beers brands, is now available to other retailers as well. The natural diamond industry, he noted, is collaborating with the Gems and Jewellery Exports Promotion Council and the government to standardize quality certifications and grading parameters.
While Pratihari does not view the synthetic diamond market as direct competition, he acknowledges the growing popularity of lab-grown diamonds and the need for regulation to ensure consumers are well-informed. India, following the Federation Trade Commission (FTC) guidelines, now mandates that synthetic diamonds be clearly labeled as such, with further developments expected in grading standards.
In terms of retail growth, De Beers is optimistic about India’s diamond market, projecting it will grow from $8.5 billion in 2024 to $17 billion by 2030. To tap into this potential, the company plans to significantly increase its retail presence, including opening 100 exclusive outlets for its Forevermark brand, with the goal of reaching $100 million in sales by 2030.

Christie’s To Present 5.5 cts “Ocean Dream” At Geneva Magnificent Jewels Sale, Expected To Achieve Up To USD 12.8 Million
Ocean Dream, The Largest Known Fancy Vivid Blue-Green Diamond In Existence, Classified As A Rare Type IIA STONE.
Christie’s has announced the upcoming offering of the Ocean Dream, the largest known fancy vivid blue-green diamond in existence, at its prestigious Magnificent Jewels auction in Geneva in May 2026. The extraordinary gemstone is expected to achieve up to CHF 10 million (approximately USD 12.8 million).
Weighing 5.50 carats, the triangular-cut diamond is graded fancy vivid blue-green, SI1 clarity, and classified as a rare Type IIa stone. The gem is set in a ring featuring an intricate mount adorned with sculpted rock crystal, alongside round and pink diamonds, underscoring its exceptional craftsmanship and design.
Certified by the Gemological Institute of America, the Ocean Dream holds the distinction of being the largest vivid blue-green diamond ever graded by the institute. The polished gem originated from an 11.70-carat rough discovered in Central Africa, further enhancing its provenance and rarity.
This marks only the second time the Ocean Dream has been presented at auction. It was previously sold by Christie’s in Geneva in May 2014, achieving CHF 7.8 million (approximately USD 8.7 million at the time), and has since remained in a single private collection for over a decade.
The diamond’s legacy is further enriched by its inclusion in the renowned “Splendor of Diamonds” exhibition at the Smithsonian Institution National Museum of Natural History in 2003, where it was recognized as one of the world’s most exceptional diamonds.
