A special brilliance that overturns common sense. A world-quality diamond cutter brand created by the Tolkowsky family, who created the "ideal round brilliant cut," the origin of brilliance, which is the root of more than 90% of the diamond cuts currently in circulation around the world. We will deliver the gem of the gem by sticking to the manufacture (in-house integrated production) that is particular about purchasing rough stones, cutting and polishing, ring design, and sales.
