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.

GIA Celebrates World Diamond Day Highlighting Iconic Gems
Institute Spotlights Historic Diamonds Like the Hope, Dresden Green, Winston Red, Taylor Burton, Motswedi
The Gemological Institute of America (GIA) marked World Diamond Day on 8th April by highlighting a selection of historically significant precious stones it has examined, underscoring their rarity, scientific importance and cultural legacy.
Below is a concise analytical breakdown of the stones and their significance from a trade, scientific, and storytelling angle:
Key diamonds highlighted
- Hope Diamond (45.52 ct, Fancy Deep greyish blue)
Traced to Golconda‑type deposits in India, this stone passed through French royalty before entering private and then museum collections, and today sits at the Smithsonian. Its combination of intense blue colour, provenance, and storied “curse” lore has made it one of the most‑recognised diamonds in the world, frequently used as a reference point in colour‑diamond marketing and exhibitions. - Dresden Green (~41 ct natural green)
The largest known natural green diamond, with an even green hue produced by natural ionising radiation in the crust. Its high purity and Saxon–European royal‑court history make it a benchmark for both rarity and the link between gemstones and political‑dynastic symbolism. - Winston Red (2.33 ct Fancy red)
A rare old‑mine‑cut Fancy red stone, of which only about 0.04% of fancy colour diamonds attain such a grade. As the only Fancy red diamond on public display, it is a key reference for dealers and collectors benchmarking the value of red‑dominant fancy colours. - Taylor‑Burton Diamond
A 68‑carat pear‑shaped D‑colour stone cut from a 240‑carat rough from South Africa’s Premier‑type deposit, later made famous by Richard Burton and Elizabeth Taylor. Its celebrity‑driven glamour elevated high‑colour‑clarity white diamonds into pop‑culture icons, reinforcing the “diamond as romance” narrative that still dominates bridal jewellery advertising. - Motswedi Diamond (2,488.32 ct rough)
Recovered in Botswana in 2024, this is the second‑largest gem‑quality diamond ever discovered and a high‑purity Type IIa crystal. Its size and purity allow scientists to study how carbon crystallises under extreme pressures deep in the Earth, making it a research‑grade specimen as well as a commercial headline‑maker. - Several stones—Hope, Dresden Green, Taylor Burton, and Winston Red—carry strong narratives of royalty, curses, Hollywood romance, and extreme rarity.
- GIA’s highlighting of these gems on World Diamond Day is a strategic blend of education and soft branding:
- It positions diamonds as objects of history and art, not just commodities.
- It reminds buyers, retailers, and media that GIA sits at the centre of authenticating and contextualising these legendary stones.gia+1
Beyond these diamonds, GIA has documented historic and royal artefacts such as the Marie Thérèse Pink diamond and the Mughal era “Mughal Spectacles,” helping to codify their gemmological and provenance data. This work reinforces its positioning as both a research institute and a preserver of the cultural heritage layer of gemmology, bridging ancient craftsmanship with modern scientific verification.
