There are many types of pearls: salt water to fresh water, naturally occuring and cultured as well as man made. There are all shapes and sizes of pearls which have different names and uses. And there are pearl like substances such as abalone and mother of pearl which are actually the lining of mollusks or bivalve shells. These substances, as well as pearls of all kinds have for centuries been coveted and considered the royal gems for jewelry making. I work with a variety of pearls and hope you will enjoy my collection.
