Trio of Sterling Silver Rings with stones, size 6

Please see the photos for details and let me know if you'd like any others. The two orange stones are smooth cabochons, the yellow clear stone is faceted. I don't know what the stones are but given the original price I know that they are something "real"! No guarantee that they are Chan Luu because I cannot read the inscription inside but I purchased them along with a Chan Luu bracelet from the same display at a local high-end clothing store. All are size 6. Questions? Leave a comment below!
