Wealthy Russians Surge in Investment-Grade Diamond Purchases Amid Market Uncertainty
Demand for polished diamonds up by 60% as individuals diversify portfolios with gemstones following VAT abolition and growing financial volatility.
Wealthy Russians are increasingly turning to investment-grade diamonds, with purchases of polished stones rising by 60% last year, according to VTB, the country’s second-largest bank. This surge in demand is attributed to the government’s decision to abolish VAT on diamond purchases, which has made gemstones a more attractive investment option.
Oksana Semenenko, vice president at VTB and head of its private banking division, explained that the rarity and uniqueness of diamonds make them especially appealing during times of rising financial market instability and tighter investment restrictions. Many affluent clients are now incorporating alternative investments, including diamonds, into their portfolios, typically allocating 5-10% of their assets to these tangible assets for diversification.
This shift comes amid increasing sanctions from the G7 and restrictions on Russian currency, which have impacted Russian diamond exports. In response, Alrosa, the state-run diamond mining giant, is turning to alternative markets to sell its goods. The company’s Diamond Exclusive program focuses on polishing its largest and highest-quality diamonds, particularly stones of 3 carats or more, to be sold directly to investors through partnerships with VTB and other financial institutions.

Diamond Foundry Grows 200mm Single-Crystal Diamond
The company revealed a continuous diamond disc matching the 200mm silicon wafer size used in many power and analog chips.
US lab grown producer Diamond Foundry says it has produced the world’s largest single-crystal diamond, measuring 200mm in diameter, twice the size of its previous record-setting achievement.



The term “single crystal” means the diamond, which has been grown for electronic components rather than the gem trade, is one continuous piece of diamond in which the carbon atoms maintain the same orderly structure throughout, rather than being made up of numerous smaller crystals joined together.
Producing a crystal this large is exceptionally difficult. Variations in temperature, plasma conditions or chemical composition can introduce defects, impurities or changes in crystal orientation. Maintaining a consistent atomic structure across a 20cm diameter makes the process particularly challenging.
The 200mm crystal can be sliced into thin, circular discs, known as wafers, retaining its diameter. These provide the base material for manufacturing electronic components. Larger wafers offer more production area, potentially allowing more components to be made from each disc
