Bright Blue Cushion Cut Ceylon Sapphire and Diamond Three Stone Ring

The Mallory 1.90 ring is an AB original design made right here in NYC. The ring centers a C. Dunaigre-certified 1.90-carat Heated Cushion Cut Ceylon sapphire. On either side of the sapphire is an Old European Cut diamond, together totaling 0.74 carats. The stones are set in our signature 18kt yellow gold. The ring is currently size 5 and can be resized!

Why We Love It 

A sapphire this tone of deep, vibrant cerulean is a special find, and wow, do we love her! Bright white side diamonds help that gorgeous blue hue pop even more and give great coverage across the finger. We are big fans of gemstone engagement rings, and this Mallory is a piece that feels special and truly one of a kind!

The dimensions of the center stone are 7.49 x 7.90 x 3.5 mm.
