Diamond cutters learned a valuable lesson from the inventors of the Princess cut who did not secure a patent and from Henry Grossbard who had exclusive rights to the Radiant shape for twenty years until the patent expired. The last twenty years have seen a myriad of new cuts; modifications of old cuts and composite cuts that have been patented and branded.

Asprey

The Asprey Cut was created by master diamond cutter Gabi Tolkowsky. To achieve this cut, Tolkowsky looked back at historical cuts and was impressed by the cushion cut popularized between the seventeenth and nineteenth centuries. With its soft, not quite square shape, Tolkowsky thought it would provide him with various options for incorporating the Asprey “A” inscription around the edges of the stone. The Asprey Cut, which was at the center of the company’s relaunch of its British luxury lifestyle house, offers a modern interpretation of a traditional design. The Asprey Cut was created to maximize light refraction to brilliant effect. All of the diamonds are cut in Tolkowsky’s studio. There are 61 facets in an Asprey Cut.

Baguillion

Like baguettes, baguillions are available in squares, rectangles and tapered rectangles. However, unlike baguettes, baguillion diamonds are brilliant cut instead of step cut.

Barocut
