Mellerio Cut

A diamond cut of the house's own, a softened oval that carries the memory of the Beau Sancy, worn alone inside a fine halo of pavé.

Piaget Solstice

Cocktail rings built like drinks: a large coloured centre stone dressed with gem garnish that opens away so the stone can be worn alone.

Four centuries of memory and one long night. The Mellerio Cut is a softened oval, an oval inside an ellipse, which the family house traces to the Beau Sancy and its royal admirer Marie de Médicis; it is worn alone in a fine pavé halo. Piaget's Solstice, from 2022, is all present tense, cocktail rings with grenadine sapphires and lime peridot that open to free the centre gem.
