Offering beautiful illumination, this contemporary trilogy ring setting is the ideal way to give her the moon and the stars! This ring mount is expertly crafted to accommodate any round center gemstone. However, select from our unrivaled collection of star sapphires to set between the two glowing, half-moon shaped side diamonds. Star sapphires and rubies display an unusual feature called asterism, an optical phenomena in which tiny, internal silk needles, naturally occurring within the sapphire crystal structure create a star-like pattern. Most commonly, star sapphires have six rays emanating from the center, cabochon-cut stone. Star sapphires create a dreamy illusion that is calming and gorgeous to observe and wear on a daily basis. Make her dreams come true with a unique custom created ring.
