Emerald and Diamond Custom Ring What do you get when you put together two emeralds and one emerald-cut diamond? You get a new twist on a classic three-stone ring.Here is what we designed; a stunning ring, with the customer's diamond in the center and two magnificent bright deep-green emeralds on each side of the diamond. To add more delicate details to the ring, we added small round, baguette, and pear-shape diamonds, all set into intricate filigree-like design. The ring is made in platinum. And that is exactly what one of our customers asked for. She owned an emerald-cut diamond set into a simple setting. She wanted to add color to the ring, and make a three-stone ring that would still be traditional, but with an unusual flavor.
