Gemstone elastic bracelet EUC jewelry

Bracelet is in excellent used condition and kept in a clean smoke free home. I tested the stone and it’s definitely a gemstone but I am not sure which stone it is. It’s a grayish green, polished, and elastic is in excellent condition. Weighs 39 grams Bracelet sits without stretching at size 7. Each (14) stone is 1” X 4/8” rectangular with slightly rounded top and polished on all sides. #gemstone #bracelet #jewelry
