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.
I purchased a yellow sapphire for about $145 with shipping and the Gem Certificate. I used the $10 shipping option and it arrived 2 days early. (Please note that if you want a Gem Certificate, it can take up to 5 days longer to be delivered) The gemstone looked exactly like the picture and video. I am so excited about the quality and price! Please note that the Gem Certificate does not say the clarity for some reason... 150% happy with this website, and would use it again!
Have placed several orders this year, but this was the largest gem order. I had several unusual requests to make and the customer service handled each beyond my expectations. CUSTOMER SERVICE COULD NOT BE BETTER. As said before ...
