Daring yet elegant, the Sia engagement ring is a unique play on the vibrant style of diamond band rings. Made in platinum and lined with diamonds along its outer edges, the ring has a contemporary feel and delivers intense scintillation and sparkle that mirrors the beauty of the round diamond center stone. This intriguing ring is set with 0.25ct of diamond melee. Diamond band engagement rings are a classy elevation of the single stone solitaire. The glamorous addition of shoulder stones gives an extra layer of diamond sparkle which is why diamond band engagement rings are so popular; after all, no-one ever complained about having too many diamonds.
