Athens Protasis is a Greek jewelry company with shops in island tourist zones. The three necklaces I am posting came from Oia, Santorini (separate listings because different color blends appeal to different people). The beads are clay. I love them, but I never wear them— and after coming all the way to the USA they certainly deserve to be out and about. ENJOY! Beautiful multicolor beaded necklace with a gradient design. Features shades of yellow, green, and teal. Vibrant beaded necklace with shades of blue, green, and purple.
