Daring yet elegant, the Sia engagement ring is a unique play on the vibrant style of diamond band rings. Made in 18k yellow gold 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.
