This original design from my studio is an entirely sterling silver Sea Turtle ring with an 8 mm Aventurine stone. This accurately proportioned ring measures 3/4 of an inch (18 mm) from head to tail and also 3/4 of an inch from side to side. Actual weight of the size 8 that is pictured is 8.3 grams. The stone is permanently secured by the Turtle’s shell and the Aventurine stone is clearly visible through the intricate shell detail. Aventurine is a beautiful green naturally occurring stone that is also known as Indian Jade because of the similar geological properties and color. I will honor all size preferences between 4 (14.6 mm) and 13 (22.3 mm); half and quarter sizes are also acceptable; same price. This design was created by me in wax and then cast in sterling silver and hand finished for a perfect ring from every viewpoint. This is the cutest and sturdiest Sea Turtle ring available anywhere. A gift box included. Thank you for visiting.
