Pearls



Pearls are the most valuable of all organic gemstones, and have been prized for 6000 years. Pearls chemical makeup varies by region and environmental factors, but the basic formula is CaCO3. Pearls form through irritants entering specific species of mollusks (oysters, clams, muscles, etc), while the irritant can be a grain of sand or a parasite, the process is the same for pearls. The irritant is coated in CaCO3(mother of pearl) to make it less irritating to the mollusk.

  2. moongem - I believe it should spell as mussels instead of muscles. My husband just cooked some last night and I noticed the spelling. Don't mean to be a spelling Nazi but it's hard not to comment when my brain picks up on things like that without my permission.
