The shiny stuff inside of seashells is called nacre, also known as Mother of Pearl. These are small fragments of Mother of Pearl in various shapes (oval, round, heart, square), with a tiny hole in each one for stringing, polished nicely, ready to be wire wrapped for jewelry, or just poured out and enjoyed! Each packet comes with five (5) pieces. They are in the 1/2" to 1" range.
[Please allow for natural variations in the stones.]
