Come on a journey to learn about the gem, pearl! Although pearls are not a rock or minerals, they best fit into the mineraloid category becuase of their calcium carbonate content, but, are organically produced by a bivalve overlaying a wound with nacre or mother-of-pearl. Pearls, one of nature’s greatest treasures, can be either freshwater or saltwater varieties. Both saltwater and freshwater varieties include cultured (man-made) or natural. Natural pearls are the rarest to find, therefore humanity has developed age old methods for acquiring these natural wonders by “seeding” or placing a bead of mother-of-pearl (same material that mollusks build to make the inside shells pearly) inside an oyster or mussel. The creature than secretes the bead with nacre over a long period of time. The creamy white liquid dries pearlescent.
Pearls are mainly used for jewelry; however, in ancient times the crushed pearl was used as a love potion and to cure insanity. Today, crushed pearl is used for pharmaceutical calcium.
