Stylish ring by Tiffany & Co. Features silver band with turquoise enamel. Presented in a classic box. This was a gift so I do not have a receipt or authenticity guarantee. I have done a lot of research and it appears authentic based on the stamp inside the ring. I have only worn this once because it is too thick for my fingers and I type a lot. The ring is a size 6. Sold as is. Please ask all questions prior to purchasing. No returns unless my description is completely off. Check out my other items. Thanks!
