Identify fake pearls

Seawater pearls are glittering, crystal clear and elegant, which may compete with gemstones and gold. Many people like to wear pearl ornaments, but many of them do not know how to identify the true and fake pearls.

False pearls are generally made of two materials

1. Glass balls coated with a substance called guanosine. This substance will give off a luster similar to fish scales and have a rainbow-like halo.
2. Thick shellsbeingground into a round shape. Also a luster similar to that of a pearl can be attained.

Characteristics of the two kinds of fake pearls

1. The "pearl" made of glass will look very bright and its shape will be very regular. If it is a necklace,the sizes of all beads will be the same. Careful observation shows that its color is dull, and it will not be as dreamyas a real pearl. A touch of these beads will be slippery instead of rough.
2. Shell grinding

They are also very round, very regular in shape, not too small, and have the luster of pearls, which can be said to be very difficult for ordinary people to distinguish. If the luster is carefully observed, it can be found that all the light emitted from it is in the form of parallel stripes, no matter what angle it is looked. This is because that the lines of a shell are parallel, while the sectional structure of a pearl is concentric.
