How to Distinguish Seawater Pearls from Freshwater Pearls

Pearls have always been the darling of jewelry circles at home and abroad. Whether they are big-name stars in the entertainment circle or ordinary friends around them, their love for pearls is beyond words. But looking at the pearl market, two very similar bead chains, but the prices are vastly different. Why? What is the difference between seawater pearls and freshwater pearls that we often hear? Today I will introduce it to you in detail.

1. The growth environment and origin are different
Saltwater pearls grow in the open ocean. It is mainly produced in the South China Sea, Japan's coastal waters, French Bosnia and Tahiti Islands, Australia and Indonesian waters.
Freshwater pearls grow in rivers and lakes. It is mainly produced in the rivers and lakes of Hunan and Zhejiang in the middle and lower reaches of the Yangtze River in China.

2. Different categories of varieties
Seawater pearls are mainly classified into: akoya pearls, mabe pearls, Tahitian black pearls, Australian white pearls, and South Sea gold pearls.
Main categories of freshwater pearls: seedless freshwater pearls, Edison pearls.

3. Different size and shape
Seawater pearls are cultured by inserting nuclei, which are grown by inserting a perfectly round nucleus into the mother shell. Therefore, the shape of seawater pearls is usually more round, and seawater pearls are generally larger than freshwater pearls.
Freshwater pearls are cultivated by implanting cell membranes, so the pearls produced are mostly irregular shapes, such as oval, oblate, egg-shaped, rice-shaped, etc., and the proportion of perfect circles is small.
PS: Usually, by turning the whole string of pearl necklaces to see if they are completely round and whether there are traces of partial ellipse, you can tell whether they are seawater pearls or freshwater pearls.

4. Gloss color is different
In terms of luster, freshwater pearls can usually be grown in two to three years, while seawater pearls take much longer to grow in natural sea areas than freshwater pearls, usually more than three to five years. The nacre density of seawater pearls is much higher than that of freshwater pearls, so seawater pearls generally have a sharper luster and a good texture, while freshwater pearls are relatively moist. Therefore, seawater pearls are superior in luster.
The colors of seawater pearls mainly include white, gold, black, silver, etc.; with the changeable iridescence, the overall color is richer and full of layers.
The main colors of freshwater pearls are white, orange-pink, purple-pink and similar colors developed from these colors.

5. The flaws are different
The texture of seawater pearls is relatively firm, and the surface blemishes are usually needle-like. This is caused by sand particles or foreign objects in the seawater entering the clam body, and usually does not affect the wearing effect.
The surface flaws of freshwater pearls are usually mainly threads and pits. Turning the beads will reveal different textures on the surface.

6. Yield and value are different
With the development of freshwater pearl breeding skills and the fact that river mussels are not picky about the growth environment, a single pearl mussel can produce dozens of pearls. The annual output value of freshwater pearls in China is more than 1,500 tons, accounting for more than 95% of the world.
The growth environment of seawater pearls is not easy to control, the breeding time is long, the risk is relatively high, and the breeding time of the mother oyster is also long, and one mother oyster can only produce one pearl, so the output of seawater pearls is very small, and the size, roundness The luster is generally better than that of freshwater pearls, so the price in the market is usually much higher than that of freshwater pearls.

The above conclusions are based on the comparison of the average quality of seawater pearls and freshwater pearls. In other words, there are also poor quality seawater pearls. With the improvement of artificial breeding technology, there are also good quality freshwater pearls, which should be compared. , or analyze specific situations.
