Watches, amazing, glistening, luminous pearls.
Even the mollusk, which’ s oyster to you and me, opens it’s shell to pass fresh-water and drizzle tiny pieces of food. Some times what it snags can be a grain of sand or part of shell. If the mollusk can not get rid of the piece of grit it starts to coat it with a substance it produces called nacre. Coating the grain of sand causes it to be irritating. Eventually you end up with a lustrous pearl.
Not all pearls are gem quality. The pearl Perlenschmuck may be lopsided, possess an irregular surface, and also the colour of this pearl is grayish as opposed to shiny. When the irregularity is simply on one side and also the pearl appears good otherwise it can be put in jewelery with the defect at the back of the bit where it will not be noticed.
Pearls could be from fresh water or salt water mollusks. Salt water is significantly more expensive.
Colors include yellow, white, pink, shades gray. South Sea Pearls, some times called Tahitian pearls, are a number of the very costly pearls. They are somewhat larger, because the mollusk is larger, and the colors really are iridescent black, black, purple, and dark gray. The pearl looks like a rainbow is playing against the dark surface.
Natural pearls are very expensive and difficult to find in jewelry since the Western began culturing pearls. Cultured pearls are just oysters in a oyster bed that’s been seeded with a nucleus.
Good cultered pearls are left from the oyster over several years to build up layers of the pearl. Cheap cultured pearls start with a far bigger seed core and then left from the oyster only long enough to collect a few layers. Those layers may burn away.
