The Valentina — 2.70ct Round Cathedral
The Valentina is the statement of the collection: a commanding 2.70 carat round brilliant carried high in an arched cathedral setting of 18k white gold, with a hidden halo tucked beneath for a second flash of light.
The Story
Cathedral settings borrow their name from architecture, and the Valentina earns it — sweeping shoulders lift the diamond clear of the hand, so it reads as substantial from across a room.
