  • Glossary of Pearl Terms S

    Here is a list of pearl terms that might help you better understand this site and the discussions within the community forum. It is compiled from multiple sources and we believe it to be one of the most comprehensive lists available.

    A | B | C | D | E | F | G | H | I | J | K | L | M | N | O | P | Q | R | S | T | U | V | W | X | Y | Z

    saltwater pearl: Natural or cultured pearl produced by a saltwater mollusk.

    sand pearls: One of four Saxony quality factors used to describe natural German river pearls; sand pearls are of low quality. Also see: light pearls (highest quality), half-light pearls (high quality), and rotten pearls (lowest quality).

    sautoir: Pearl strand longer than 36 inches (90 cm).

    Saxon pearl necklace: Necklace created from natural freshwater pearls found in the Vogtland (Germany) between 1719 to 1912.

    scallop pearl: Non-nacreous pearl produced by any mollusk of the Pectinidae (scallop) family.

    Scottish pearl: Natural freshwater pearl from Margaritifera margaritifera found in Scotland.

    seabed system: Method of farming South Sea pearls in which Pinctada maxima mollusks are placed in baskets or panels secured to posts on the sea floor. The method is still used today in northwestern Australia but was most popular in the first decades of pearl farming there.

    second-generation cultured pearl: Freshwater or saltwater cultured pearl whose growth is started either by implanting a shell bead nucleus in an existing pearl sac from which a first-generation cultured pearl was removed, or by letting the mollusk grow a beadless cultured pearl in an existing pearl sac from which a first-generation cultured pearl was removed.

    second grafts: Cultured pearls grown in existing pearl sacs after the first harvest; same as second-generation cultured pearl. The term is misleading because there is no tissue graft involved.

    seed pearl: Natural pearl less than 2 mm in diameter.

    semi-baroque pearl: Off-round, asymmetrical pearl but not as irregular as a baroque pearl.

    semi-round pearl: Off-round pearl having a symmetrical shape or a slight deviation of symmetry. To be semi-round, a pearl's diameters must vary by more than 2 percent. Also called near-round.

    shell pearl: Imitation pearl made from a mollusk shell.

    shinju: Japanese word for pearl.

    shireen: Historical Persian quality factor describing natural pearls of remarkably high luster and excellent shape.

    shiro-gai: Japanese term for white shell. It typically refers to Pinctada martensi, which has a strikingly white inner shell layer that produces very white pearls.

    sijni: Historical Persian quality factor describing natural pear-shaped pearls.

    silver-lip mollusk: Pinctada maxima mollusk that has silver rather than gold inner shell edges; used to culture South Sea pearls.

    silver nitrate: Substance used to darken cultured pearls. The compound turns black when exposed to light.

    simpatico: A term that describes the relationship, interaction between a person's skin and the differing types; colors/overtones/orient of pearl(s). A specific pearl(s) that interacts with the skin in a positive way and flatters the wearer can be said to be simpatico with that person.

    sindaali: Historical Persian quality factor describing a natural, flesh-colored pearl.

    sinjabaasi: Historical Persian quality factor describing natural pearls of the finest black color.

    slug: Several pearls fused together so they resemble a slug.

    sofri: Historical Persian quality factor describing natural pearls of a yellow color.

    souffle pearls: Trade name for Chinese freshwater pearls grown with a removable, earthen substance as a nucleus, creating hollow pearls.

    South Sea pearl: Natural or cultured pearl produced by the Pinctada maxima mollusk.

    Southern Cross, The: Cross-shaped group of natural pearls found on the Australian west coast in 1874. A vertical line of seven pearls measuring 3.8 cm had a single pearl attached to each side so the group formed a cross. It is now believed the arms were glued on. It was named for the celestial constellation that is visible only in the Southern Hemisphere.

    spat: Saltwater mollusk larva old enough to attach itself to a fixed surface.

    Strombus gigas: Queen conch snail from the Caribbean Sea and Atlantic Ocean.

    surface: One of the quality factors considered when grading a natural or cultured pearl.

    sweet water pearls: Trade term for freshwater pearls.

    symmetrical pearl: A pearl that has exactly the same shape on both sides of a central axis.

    synthetic pearl: Artificially grown pearl.

      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...
