Crisis or timing for investment? This dilemma greets the new week in mid-September surrounding the international market for precious diamonds – one of the most widespread alternative markets for safe investment havens after the art market. The reasons for this dilemma are twofold: First, the war between Russia and Ukraine that disrupted global supply chains for rough diamonds, and second, the imposition of 50% tariffs by the US on Indian products, which caused a new crisis in the processing chain (see cutting-polishing workshops) as exports worth approximately $4.8 billion were frozen, resulting in.

New reshuffles in the diamond exchange
At the same time, competition between natural diamonds and laboratory-grown diamonds has brought new reshuffles to the diamond exchange, with investors being more stringent in their choices, targeting exclusively those pieces considered more secure resales. In other words, valuation prices for diamonds of questionable origin are falling sharply, in contrast to those that are “clean” and gaining greater demand. In this logic, brands of high jewelry making play a major role as they are considered credible collectible and investment choices.

Secure investment opportunities in the first trading session at the Diamond Exchange with Bulgari, Cartier, Graff
The first board that will set the tone for autumn is in Hong Kong, where Sotheby’s auction house is preparing for opening transactions on September 19. A high selling price is expected to be achieved by a Bulgari ring (diamond, emerald) with an estimated price starting at 2.2 million Hong Kong dollars, as well as a Harry Winston ring ranging in the same estimated price.


Stealing the spotlight is a pair of JAR earrings with an estimated price of 850,000 Hong Kong dollars (€95,000), as well as a diamond Hermes necklace at the same low estimate. Many bids are expected to be gathered by Cartier necklaces, brooches and earrings with the popular “Panthers” stealing the show. An example is a Panthere ring made of onyx and diamonds, with estimates starting at 450,000 Hong Kong dollars (€53,000). Under investors’ consideration is a pair of Graff earrings (diamond, emerald) with an estimate of 260,000-350,000 Hong Kong dollars (€28,000-38,350).
