Cultured freshwater pearls are produced by mollusks, but the process is started by human intervention. Cultured reshwater pearls are less expensive because they are faster to produce with higher yields per mollusk. More about treatments
Pearls are products of bivalve mollusks (mainly oysters and mussels). They are built up of nacre (mother-of-pearl), which is mainly calcium carbonate in the form of aragonite crystals, and an organic horn substance known as conchiolin that binds the microcrystals concentrically around an irritant. Although pearls are not especially hard, only about 2.5 to 4.5 on the Mohs scale, they are extraordinarily compact and very difficult to crush.
The typical pearly luster is produced by the overlapping platelets of aragonite and film of conchiolin nearest to the pearl surface. The color of pearl varies with the type of mollusk and the water, and is dependent on the color of the upper conchiolin layer. Pearls may be natural (occuring without human intervention) or cultured; and they may occur in the ocean or in freshwater.
My citrine and topaz gems ordered from gemselect were amazing. Service was fast and the details on the website were a very good match. I would recommend gemselect.com to everyone. I will for sure be back to buy more stones too.
Stone exceeded my expectations except in regards to size. Smaller than what I had anticipated. Further education needed on my part in regards to the pear shape. Maybe that had something to do with it. Plan to contact customer service regarding return/exchange for larger size. Beautiful gem and fun to watch the tracking from Thailand.
