Diamond Emerald Wedding Rings SetDescription 2 stacking colorful rings. When I thought about the marquise engagement ring I imagined it to be set with emerald and diamonds but I wanted it to have an unusual look, that is why I set the emerald not in the middle but in the corner of the ring with a bit of tilt. The wavering was a perfect match for the marquise ring with 10 diamonds in different sizes The rings are made of 18k yellow gold with a matte finish. Ring 1: 10 Diamonds total
