Boho beaded blue string heart stone necklace

Artsy and boho/bohemian blue string and blue beaded necklace with a blue stone in the shape of a heart on it from Avon Jewelry. The heart stone measures 1 inch by 1 inch. The necklace measures 19 inches (including a 3 inch extender). There is one blue circular bead missing from the necklace (see photos), but this isn't entirely noticeable, and otherwise this necklace is in great condition with a lot of life left in it!
