Matte black painted metal hoop pendants, on powder coated stainless steel hooks. The pendants are of Metatron's Cube, a sacred geometric symbol connecting 13 circles with Hexagrams/Stars of David. It's the symbol of Archangel Metatron, and because this symbol is derived from the Flower of Life, its sometimes referred to as the "Fruit of Life". Hoop is about 1.75" diameter, and bow out slightly, like a shield. They are rather heavy, since they're made of metal.
