The 6th and final stage in the diamond pipeline is selling the diamond jewelry to the consumer. Various retailers such as Tiffany and Company and Cartier sell diamond jewelry straight to the consumer. The diamond industry is a multi-billion dollar industry with sales values recorded at over $72 billion dollars a year. Diamonds are the most sought-after luxury good in the world by both men (as gifts) and women (for themselves). The United States represents the largest market for diamond jewelry with 50%, a distant second is Japan with 15%, and Italy is third with 5% of all diamond jewelry sold there.
Many thanks to the author for this quality research on the topic of diamonds. But here it would be worth mentioning the De Beers corporation. It controls 37% of the world’s diamond production and can significantly influence prices. I saw once their luxurious exhibition stand built by CARSHE at the international jewelry exhibition Vicenzaoro in Italy. It seemed like it cost a fortune. But they can afford it because their turnover for 2023 is estimated at 4.27 billion dollars.
