This sand dollar fossil is from Madagascar and is approximately 145 million years old. It was cut by Gary Wilson of Arizona. I set it in a handcrafted, sterling silver setting. It is just over 2.5 inches long including bail and is hung on a black leather necklace adjustable between 16.5- 19 inches. The pendant can be removed from the necklace for a variety of looks. Complimentary polishing cloth included.
