Scallop Pearls (Pectinidae)


  • Scallop Pearls (Pectinidae)

    Scallop Pearls Defined

    A scallop pearl is a non-nacreous calcareous concretion produced by any member of the Pectinidae (scallop) family. Pectinids are known for their uniquely blue colored "eyes" (actually, known as simple-eyes) found in their mantle and for their ability to "swim" using their shells and mantle to create stong "jet-streams".

    Scallop Pearls, the Pacific "Lion's Paw"

    Unlike other non-nacreous pearls such as the melo-melo and conch pearls, the scallop pearl comes from a bivalve mollusk known as the "Mano de León", or "Lion's Paw" or Nodipecten subnudosus. This shellfish garners its name due to the unique shape of its shell, which resembles a lion's paw

    Scallop pearls are native to the coastal waters of Central and North America and most commonly found off the coast of Baja California and the Gulf of California in Mexico. There is a cousin species of this one off the waters of the Atlantic Ocean, around Brazil (Nodipecten nudosus) but there does not seem to be a fishery for this species, nor pearls.

    Scallop Pearls are a Very Rare

    The scallop pearl is an exceedingly rare occurrence and is the bi-product of wild-harvested scallops for the seafood market. Due to the rarity of the gem, scallops are not actually fished out for their pearls. Scallop fishermen, men that actually spend their whole lives harvesting the meat of this shellfish, may only find a small handful of pearls during their entire lifetime.

    Scallop Pearls are Uniquely Colored!

    Scallop pearls have a unique shape and coloration absent in other calcareous concretions. Scallop pearls are generally symmetrical in an oval, round, drop, or button shape, but baroque shapes are also very common.

    These pearls range in size from tiny "seed" sizes (1 mm) to quite large (40 carats). The color of the scallop pearl is unique among all porcelaneous pearls. Scallop pearls generally exude a rare maroon to plum coloration, and are also commonly found in white, deep purple and orange colors.

    Scallop Pearls Display a Unique 3-D Visual Effect

    The scallop pearl has a unique 3-dimensional effect within the reflective platelets of their surface, which adds to the unique beauty of the gem. This gives the pearl a sort of flash effect, similar to the flame-like appearance of the conch pearl.

      It is at this particular crossroad that we find a Mexican-French Medical Doctor by the name of Gastón Vivès, attempting what very none had tried before: initiate a commercially viable, large-scale pearl oyster farm to produce shell and pearls. The Vivès family owned a pearl fishing armada in La Paz, Baja California Sur, and they were experiencing diminishing profits every year, thus wanting to revert this trend we find Gastón Vivès...

      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...

    • 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...
