Unique Larimar Gemstone Handmade 925 Sterling Silver Bangle Jewelry Adjustable

It doesn't look like in the picture, I unfortunately can't determine what kind of stone it is, the earrings look more like larimar, but the workmanship is good, it looks good on the arm, for that reason I also decided to keep it, otherwise I doubt that it is genuine larimar stone. L. G. Irina
