Mystic topax & sterling silver ring size 5.5

Majestic topaz set in sterling silver .925. Beautiful purple, green, blue stone. Size 5.5 Have had this ring for approximately 3 years. Still in mint condition. Stone has no scratches or chips and ring is stunning on. I think the cut is a cushion or an emerald. Never been appraised it was given as an engagement ring. Would look stunning on anyone's finger. 🤗😎🤞
