This is an amber bracelet. It has the power to expel unnecessary energy from the body and bring in fresh, bright energy. It is popular as a charm to be blessed with children and to wish for a safe and healthy delivery. ★★Amber is not a mineral, but fossilized resin derived from plants, and it is somewhat "light!" (✯ᴗ✯) It has a low specific gravity and floats in salt water. Therefore, it does not have the "heavy!" weight of natural stones, so please understand. But it's beautiful! ( ꈍᴗꈍ)
