Perlas cultivadas en agua salada
Pearls belong to the class of organic gemstones. They are products of bivalve mollusks (mainly oysters and mussels) built up of nacre (mother-of-pearl), which is mainly calcium carbonate in the form of aragonite crystals, and another type of organic horn substance known as conchioli.
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 colors of pearls can vary depending on the type of mollusk and the water they were formed in. Natural pearls are incredibly rare and extremely valuable (occurring without human intervention), so most pearls available today are actually cultured pearls. Cultured pearls are available as both saltwater and freshwater pearl.

First, I wanted to say that you guys have a great selection gems, in all price ranges! Awesome site!! My son found a 6 piece set of blue topaz hearts that he wanted to get. I wanted to view all of the 6 piece sets or 10 piece sets. I recommend adding that ability to your filter.
