This is a beautiful 18k panther ring. Made by Carrera y Carrera the Tiffany of Spanish Jewelers and I understand the jewelers to the Royal Family of Spain.. The detail of Carrera y Carrera jewelry is impeccable and earned them the reputation they enjoy today. Look closely at the detail on the panther and you will understand. I have tried to have it re-created in a brooch but no one has been able to copy it well enough to be used with the ring.This ring is 18 K, the panther has aruby eye and sits on a circle of black onyx and flanked with 4 diamonds. I take a ring size 7 and this must be a 6 because I used it as a pinky ring but it can be re-sized. Another seller has the matching pendant to this ring in another sale. THIS IS A FINAL SALE SO PLEASE ASK ALL QUESTIONS. I will be posting the weight of this ring as soon as I get it to a jeweler. Thank you for looking.
