The estimated cost of the last De Beers site was $ 550 million; the company adjusted the composition of the boxes by improving the quality of diamonds, Rapaport reports.
Sightholders note that although in general, De Beers kept the prices for rough diamonds at the same level within the site that ended on February 28, due to the change in the range, the boxes went up by about 4%.
"In general, the boxes look very attractive, and I believe that the site received good feedback from customers," said one of the sightholders. "De Beers has changed the assortment, so the prices have slightly increased, but this increase looks justified."
Prices for rough diamonds in February showed an increase, and according to some reports, BHP Billiton tender prices increased by 4% on average. Similarly, bonuses for De Beers pits, which are traded on the secondary market with a 5 percent premium, increased. Prices for large diamonds weighing more than 15 carats jumped by more than 12%.
Dealers note that premiums vary depending on the type of product, cheaper diamonds are sold at a premium of about 8%, while more expensive stones are traded at low premiums.
One of the Indian sightholders expressed concern over the fact that despite the recent rise in prices for raw materials, prices for polished diamonds remain stable.
