About Pearl

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 (occurring without human intervention) or cultured; and they may occur in the ocean or in freshwater.

I had a limited budget and wanted a star ruby. GemSelect offered small, but pretty stones at a very reasonable price. I've always been satisfied with my GemSelect purchases, although there are also eBay vendors I use for less expensive gems. Their selection of more expensive stones, like rubies, is very limited, however.

I decided recently to start a gemstone collection! I searched online for a reputable gem merchant and found gem select! Their selection is gorgeous and I’m excited to receive my first package! Checkout was a breeze!
