This original design is a sterling silver ring featuring two Frogs holding an 8 mm Aventurine stone. This ring has a solid shank that separates near the Frogs creating a secure mounting that shows the beauty of the stone. The Frogs are completely detailed on all sides and so happy to be holding this beautiful gem stone. Aventurine is widely known as Indian Jade and has the same luster and hardness as green Jade. This is a size 8 ring but I will honor any size request up to US size 13 (22.3 mm in diameter); half and quarter sizes as well. All of my Etsy listings are clearly marked as sterling silver and I always include a nice gift box. Thank you for visiting.
