Mellerio Cut or The Tiffany Setting
Mellerio · Tiffany & Co.
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.
The Tiffany Setting
Six slender prongs lift a round brilliant diamond clear of the band, so the stone, not the mount, carries the ring.
One house invented a setting, the other a cut. Charles Lewis Tiffany's contribution of 1886 was structural: six prongs that lift a round brilliant above the band. Mellerio's lies in the stone itself, a cut of its own, an oval held within an ellipse, which the house traces to the Beau Sancy, the diamond favoured by Marie de Médicis, who granted the family its privileges in 1613. The Tiffany Setting and the Mellerio Cut were each a way of making a house's diamonds recognisable at a glance.
