Zales Cushion Cut Amethyst RIng with Diamond Frame 10K Gold

This is a pre-owned cushion cut Amethyst Ring with pave diamonds. It was purchased from Zales. Maybe worn to dinner twice. Excellent condition. It has sat in the original box. It is in 10K white gold. Currently sold on Zales website for $599. It is women's size 6-6.5. I am selling because I have developed an allergy to gold.
