This is a two piece set that includes an engagement ring and ring guard. The solitaire ring has a round cubic zirconia center stone that is 7mm in size and the equivalent in size to a one carat diamond. The stone is held with four prongs and the ring has a plain shank. The ring guard is chevron shape and it surrounds the center stone when they are worn together. The ring guard has nine small clear cubic zirconia stones on each side for a total of 18 stones that are hand set with tiny prongs you can barely feel. When the two rings are worn together the solitaire fits snuggly inside the guard so it cannot be seen at the bottom. This would make a great ring to wear on vacation when you do not want to wear your expensive jewelry and the solitaire can be worn alone for another look. In rhodium plated brass and genuine cubic zirconia.
