The Mastercut diamond is a perfectly proportioned and symmetrical Round Brilliant diamond cut with 32 additional facets for that extra Sparkle. Each diamond will have Mastercut's signature and unique eight-pointed star expertly faceted into the culet which can be seen through a Stargazer. Developed by Tolkowsky, it comes from a family with seven generations of superior diamond-cutting skill. Every Mastercut diamond is ethically sourced and individually serial-numbered, and is set in Fairtrade Gold.

The Starlight collection features traditional four-claw setting and a D-profile band.
