The Knowledge about Pearls

How to identify the differences between freshwater pearl and seawater pearls ?

Freshwater Pearl’s biggest drawback is low density. A freshwater pearl can be produced more than 10-20 pieces of the freshwater pearls, even can grow from a anucleare pearl to 7-8MM pearl in two years. Such a fast growth rate caused by the relatively loose structure of the beads quality. Therefore this relative low density in the pearl’s surface exposed, it lacks the kind of solid water beads delicate, moist texture. Compared with the grade of seawater pearl, sea pearl’s luster is more sharp! Therefore, freshwater pearl luster is easy to subside. Otherwise, a anuclear freshwater pearl beads are not worth the present value.

Of course, in terms of consumer attitudes, pearl is a kind of loss of goods.As for wearing pearl limitation, to distinguish a nuclear or anuclear freshwater pearl is not the identified standard line.
The following aspects of the difference, you can learn to identify:

From the shape

Seawater pearl farming is the use of interpolation of nuclear technology, is to wear a good first round pearl necklace bead core, insert the sterile pearl of the gut, and next to the bead core and then insert a small patch of cells, the cell will be a small piece in the bead core around to form a pearl sac, and secrete nacre, evenly wrapped in its outside, so that it will grow up big and round pearls. If there is bias in the garden flat beads, that is, fresh water pearls.

Freshwater pearl farming technology is the use of Insert sterile beads, is the first of a healthy mussel’s mantle edge parts into small pieces, then inserted into these cells, a small piece of the mantle within the education Zhu Bang, for they become pearls. Using Insert sterile difficult to obtain Shoen pearl beads, generally m-shaped, oval or oblate.
Therefore, to judge whether it is a pearl beads, from the initial shape is critical.

From the Flaws:
The pearl beads surface of the screw-shaped defects rarely occur (even if it is very shallow thread), freshwater pearls are a common thread, so once the super beads thread-like defects occur (even if it is very shallow thread), You can determine this is a freshwater pearl necklace beads , rather than the  seawater pearl necklace beads.

From the Luster :
In general, the water beads produced in the clean sea water. Shiny gorgeous, good quality beads, beads texture are better than the fresh water permeability. Freshwater pearls produced in the rivers and lakes, the general quality of white beads are in flash ash, they are more turbid.

The main origin of seawater pearls: Guangxi, Guangdong, Hainan, the coastal areas. China’s first cultured pearl on a sea was birthed in Beihai, Guangxi.
