A ring-shaped synthetic diamond





A record ring 3,865 carats entirely cut by a diamond. But it is synthetic ♦ ︎

The great run of synthetic diamonds is also played on a ring. It is the one made by Dutch Diamond Technologies. In fact, the company created the first ring made entirely with a diamond produced in the laboratory. The diamond-ring also has a name: Project D. Of course it is a special production, but it is indicative of how the synthetic diamond market can evolve. The D of the name indicates, among other things, the tenth anniversary of the Dutch Diamond Technologies.

The ring was made from a large diamond produced in a 155 carat laboratory.
The synthetic diamond was then polished and cut with the laser. It has 133 facets, compared to 57 of a standard brilliant cut. In total it weighs 3,865 carats.

In short, it is something that could hardly be done with a natural stone. According to Dutch Diamond Technologies until 2017 it would not have been possible starting from a large synthetic diamond. In 2011 the Swiss jeweler Shawish, has already proposed a ring made with a single natural diamond crystal. And similar is the project announced by Diamond Foundry, but the production phase would not have started yet.
Project D was produced in Holland, cut in the Netherlands and classified in Hrd Antwerp, Belgium. The synthetic diamond was created with the Cvd technique, Chemical Vapor Deposition (chemical vapor deposition synthesis). It took five weeks to produce it in these dimensions. Hrd Antwerp has thoroughly analyzed the ring and classified it: Clarity VVS2, Colour E, Fluorescence NIL, Polish Very Good and Symmetry Excellent. In short, nature could hardly offer a similar result. Federico Graglia
