According to the cause of formation, it can be divided into natural pearls and cultured pearls.

According to the reasons for use, it can be divided into medicinal pearls and ornamental beads.

According to the water quality, it can be divided into freshwater pearls and seawater pearls. In general, freshwater pearls are produced from freshwater mussel and the sea water pearls, of course is the production from marine shellfish.

Such as: pinctadamartensii, whitelip shell, including abalone oh.

After understanding the classification of pearls, we must also understand that "not all seawater pearls are more expensive than freshwater pearls". Under any classification, there are advantages and disadvantages.

However, the price of sea pearls is generally higher than the price of freshwater pearls, specifically, for the following reasons:

1. is more rare

Sea pearls are more precious than fresh water pearls in their rarity.

We give an example: Freshwater Pearl in the annual output of about 1200 tons each, freshwater mussels can breed a 30-40 freshwater pearl, and affected by the weather and farming technology limited, Akoya sea pearl production is difficult to control each year, only 60 tons, plus each pinctadamartensii only breeds a, and each of the 3 only a shell can be successfully bred.

That is to say, Akoya sea pearls, the production of only 5% of the freshwater pearls. While the other 2 kinds of rare sea pearls, Nanyang pearl and Tahiti pearls, the yield is more scarce and precious

2. more rounded

Sea pearls are more expensive than freshwater pearls in their round shape.

Seawater pearl each mother of pearl breeding a pearl, pearl won't squeeze each other, so the finished grain roundness. But because most of the non nuclear freshwater pearl farming, the formation of different shapes, rarely nearly oblate, circle and circle and ellipse type, water meters, and.

Therefore, the national standard requirements for higher standards of seawater pearl circle, we often contrast will find that the seawater pearl is more accurate circle.

3. more beauty value

In addition to a more round shape, the other pearls of sea water are also very high.

The pearl gloss: parts of seawater and freshwater shellfish shellfish is different, the secretion of nacre is also different. Most sea pearls, freshwater pearls and stronger than the general gloss and shiny, with a hint of moist skin, often look better.

Color: the common natural colors of fresh water pearls are three kinds of white, pink and purple. Chinese and Japan Sea Pearl mainly dominated by white, the Nanyang pearls have elegant pure white with golden extravagance, greenish or bluish gray penetration is a natural color with Tahitian pearl.

Knowing these three reasons, we will know why seawater pearls are more expensive than freshwater pearls, and the price of pearls is closely related to their rarity, quality and the natural regulation of the market.
