Hi John, The queen conch is Strombus gigas, which actually means "giant conch". Pearls can be produced by a wide variety of bivalves, possibly all bivalves, I'm not sure. They also form sometimes in gastropods. However, not all pearls are created equal. A pearl forms when the mollusk responds to an irritating speck of sand or grit that accidentaly gets inside its shell, and which it cannot expel by the usual water currents that pass through the shell. The animal's mantle, the organ which secretes the shell itself, secretes a layer of shell material over the offending object, smoothing it so that it doesn't irritate the soft tissues of the mollusk. It then continues to secrete additional layers, so the pearl gradually grows in size. So, the exterior surface of the pearl resembles the interior surface of the shell. If the bivalve is a venus clam with a chalky white interior, then a pearl produced in that animal will have a chalky white exterior, and no value as a gem. Giant clams sometimes produce pearls the size of golf balls, but of no value other than scientific. If a shell has a shiny pink interior (like the queen conch) its pearls will be shiny and pink. What sets the pearl oysters apart is that their shells are lined with the beautiful, iridescent "mother of pearl" that is so often used in jewelry. Hence, the pearls of those species are equally beautiful and "pearly". Fresh water mussels also have pearly interiors, and produce "semi-precious" pearls, often used in jewelry, but not worth as much as pearl oyster pearls. Even small worms and shrimp that crawl into a pearl oyster sometimes end up as odd-shaped pearls. Queen conchs are farmed in a number of places in the Caribbean, but queen conch pearls are not as far as I know, because they don't have value as gemstones. By a cutaway "view" of a queen conch, do you mean a picture or an actual shell? In either case, if you contact me privately I may be able to help you out. Regards, Paul M.
