About pearls!

- Categories : Pearls

Obviously they are all "natural", although strictly ............... "cultivated"!

Historically, the cultivation of pearls occur in salt water and places of production are Japan and South Seas (Australia and Tahiti).

The pearls of Japanese sea, reaching diameters of max 10 mm), are the most widely appreciated along with South Sea pearls (diameter 9 -18 mm), and Thaitiane (diameter above 20 mm).

Recently, have been added the pearls of Chinese production whose quality is not as good as the Japanese, but is still in continuous improvement

The capacity to breed shellfish suitable for the production of pearls was soon extended to the waters of lakes and rivers, giving rise to the production of pearls set of "freshwater or river."

Initially these beads had a "grain of rice" conformation (defined as "scaramazze"), but today, with the general evolution of technology, reached spherical shapes and sizes up to 12 mm.
Even their appearance (nacre, East etc.,) is greatly interesting, so that makes them easily confondondibili with those of the sea.

The value of freshwater pearls is considerably shorter than those of the sea, as the mollusk that generates is considerably larger and more "prolific" of corrsipondente marine oyster.
To create a pearl of the sea is in fact necessary for man to enter manually in each oyster, a foreign body (a sphere of mother of pearl), which allowed the pearl oyster same process; Normally, a single pearl per oyster.

To generate the pearl of fresh water is instead simply insert small fragments of epithelium that will result from 10 to 20 beads per clam.

The visual recognition of a spherical pearl of sea dall'omologa of river is not easy and you must trust their jeweler.
However, a sensitive hand could instead appreciate the difference in weight between a pearl wire of sea and one of river, as long as the size of the beads are the same: the string of pearls of the sea will have a greater weight.
In fact, the pearl of the sea has in its interior the core of mother of pearl (inserted by man), which has a density and therefore a greater weight of the structure characteristic of the fresh water pearl.
