Fancy Colour
Vivid blue, pink, yellow and green diamonds are a signature of the house, in every shape and size: from a 2.10ct vivid blue pear to a 10ct vivid yellow cushion.

Bespoke
Every commission starts with a conversation. Your idea becomes a sketch, then a 3D render you approve before a single stone is set.
“Figure skating shaped my life, and the Olympic spirit — discipline, resilience, and elegance under pressure — remains part of everything I create.”
