Keshi Tahitian Pearls are very special because they are made up of the precious material of pure nacre. They are highly prized for their extraordinary luster and beautiful organic shapes.
 
Nacre,  also known as mother-of-pearl, is a crystalline substance that creates the iridescent visual effect attributed to pearls!
