Natural Pearls chemical properties tips
by: Anonymous

Do you mean your pearls are Natural Pearls, from freshwater pearl mussels or saltwater pearl oysters?

The Major chemical properties of Natural Pearls are:

85 - 90% CAlcuin carbonate, 10 a 15% organic conchiolin and 2 - 4% water. Natural pearls have a hardness of 21/2-31/2 on the MOHs scale. Not very hard.

Natural pearls are rare and expensive. The reason is because the historic pearl fisheries for these pearls are no longer operational. So if you discover your mulit-strand of pearls are Natural Pearls, you have a good reason to celebrate!

Their value greatly depends on this Natural differentiation. Please get back to us and let us know your findings. 👍

Best Wishes
Yvonne
