Necklaces from Freshwater Pearls

By Derek J Lamington


Nacre is applied to foreign objects that end up inside of oysters. In the past, pearls were important financial assets, comparable in price to real estate investment, as countless oysters needed to be sought out only one pearl. They were rare simply because were created only unintentionally.

Many pearls are created by man when they put a grain of sand into an oyster with the hope that it will start forming layers of nacre around the sand. The pearls are later harvested, when the oyster has covered the sand with layers of nacre. Most cultured pearls are designed in Japan. While in the warmer waters with the South Pacific, larger oysters produce South Sea cultured pearls and Tahitian black cultured pearls, which have been larger in space. Freshwater pearls are cultured in mussels, mostly in China.

The standard of pearls is judged by the orient, which is the soft iridescence caused by the refraction of sunshine from the layers of nacre, and luster, the reflectivity and shine in the surface. Fine pearls do not have any flaws or spots from the nacre: there's an even, smooth texture.

Cultured and natural pearls might be distinguished from imitation ones by the really easy test. Consider the pearl and rub it (gently!) contrary to the side of a tooth. Cultured and natural pearls will feel slightly rough, like fine sandpaper, as a result of texture of natural nacre. Imitations will feel as smooth as glass because surface is molded or painted for a smooth bead.

Choose from classic creamy white pearl necklace or even the more exotic black Tahitian or pink pearl necklaces that are available? In the event you purchase a single strand or multi-strand necklace? This post will make an attempt to explain a number of the basics when looking for a pearl necklace such as type of pearls used in building a necklace or the colour in a variety of pearl necklaces.

A pearl necklace will use a palette of colours between white to black. Colours generally cover anything from cream to silver-white, but can reflect other overtones from the surface such as a rose glow. Colour does not affect the quality of pearl necklaces, but is just a personal preference. Generally a necklace of white pearls is considered the most popular in the country, while silver pearls are the most desired in Asia.
