Product Name: RARE Antique solid 10k gold pin conversion retailer ring-AMAZING!!
Size 6.25 This ring is very rare because it was originally a pin and turned into a ring :) This antique ring is solid 10k gold with peridot. Photos 6-7 show the band on this ring. It has a curve; and was made this way. It's unusual and not like normal bands so it was worth mentioning.
