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.
Very fast shipping from Thailand to Conus. Gems were as advertised. Compared to some other the other gem dealers on the web I've dealt with Gem Select are very professional. Will definitely do more business with this proprietor.
First time visiting this site. I found it very well-organized which made it easy to find what I was looking for. I also like that the gem pictured was the actual gem you were buying and not a stock photo.
