The center stone in this ring is a 10mm by 6mm marquis cut high quality, fully faceted aqua spinel, which is a stone that is more expensive than cubic zirconia. To get this color, most other companies would use crystal, but we use the spinel stone. There is a 4mm clear princess cut stone on each side of the center stone and 3 tiny princess cut stones that are channel set into the band on each side. The design steps down from the center stone which adds dimension to the ring. Ring would make a great engagement ring substitute as it looks just like fine jewelry. Stones are all hand set into rhodium plated brass.
