Stunningly huge, 8mm, lab-created rubies. The face of the stone is 5/16 inch and each stone is more than 1.50 carats. Clear, gorgeous, deep red color; set in an open cage to allow in the most light. These lab-created rubies have all the best features of a ruby but none of the fissures or the big, big price. I have only one set available, my sister got the other pair.
