    Natural Pearls Defined

    Natural pearls are calcium carbonate secretions which form within mollusks without human intervention.

    Natural Pearls - Accidents of Nature

    Natural pearls are formed randomly and really are simple accidents of nature. When a certain type of irritant, such as a parasite, becomes lodged in the tissue of a mollusk, the animal responds by secreting a calcium carbonate substance called nacre to coat the intruder and protect the mollusk. Over a period of several years, this build-up of nacre forms a natural pearl.

    Discovery of Natural Pearls is Rare

    Natural pearls are extremely rare. Instead, since the early part of the 20th century, cultured pearls have supplanted natural pearls as the most common and available pearls.

    Cultured Pearls vs. Natural Pearls

    Cultured pearls are still real pearls, grown organically inside of oysters in the same way as natural pearls. The only difference is that in the case of cultured pearls, the pearl farmer intentionally stimulates the development of the pearl by inserting a "nucleus" into the oyster. Thus, the formation and discovery of the pearl are no longer left to chance.

    Natural Pearls Today

    Although natural pearls are found primarily in older jewelry from estate sales and auctions, their popularity is making a comeback. Colorful abalone and conch pearls have begun to find favor in exotic, unique designs. As new species of clams and scallops are being fished to drive the fishery markets, new varieties of natural pearls are being found all over the world, each being unique an distinctive as the species that bears them.

    Back in 2007, a double strand of 68 perfect natural pearls known as the "Baroda Pearls" was auctioned at Christie's Auction House for $7.1 million American dollars.

    And back in 2015 a record breaking natural black pearl necklace made with Mexican Gulf of California pearls was auctioned at Christie's. The amazing "new pearl necklace" (pearls were fished in the 21st century).

    The necklace comprises four strands of 81, 76, 69 and 63 natural gray and brown pearls, measuring approximately 12.65 to 4.90 mm.

      The arrival of the Iberian Conquerors

      The Native Nations had no real interest in establishing a commercial venture in pearl fishing and we understand little to nothing of the way they fished for pearls, since most of the information was either lost or destroyed during the conquest of Mexico. The rich plunder of the Conquistadores was sent to Spain and later dispersed all over Europe. The most significant information we have on the subject comes from the period of colonization of northwestern...

      A review: The History of Pearls in the Gulf of California, Mexico
      By Douglas McLaurin-Moreno


      Since unrecorded time, man has obtained many bounties from the world’s oceans: food, shells, corals, sponges, seaweeds, and the most desirable of all of these were the beautiful mother-pf-pearl shells and their valuable treasure, Pearls.

      Mexico has four species of pearl oysters inhabiting its coasts, two -the larger sized- on the Pacific side: the Panamic Black Lip...

    • The French Blue
      by WayneCMS
      By Richard Wise I was fortunate enough to get an early Kindle edition of Richard Wise's newest masterpiece The French Blue. I also own a copy of Wise's Secrets of the Gem Trade, and it is one of the very few gem books that I've read cover to cover, not just skipping ahead to the sections about pearls. The French Blue is a completely different kind of work. It is a novel that begs to be read slowly, but once one becomes entranced in the story, it is nearly impossible to put down. Not for the f...
