How many kinds of pearls are there?

Pearls can be divided into natural pearls and cultured pearls.

1, natural pearl

Pearls formed by wild shellfish in natural environment. Natural pearls can be formed in seawater, lakes, rivers and other environments suitable for growth. These pearls are very rare and expensive. Generally speaking, the higher the quality of pearls, the rounder the pearl center, and the higher the value of pearls.

2. Artificial cultivation of pearls

Artificial pearl nuclei or foreign bodies are inserted into cultured pearl mussels, and then cultured to gradually form pearls. Nowadays, most of the pearl markets are cultured pearls. According to the characteristics of pearl core and foreign body, cultured pearls can be further divided into nucleated pearls, seedless pearls, regenerated pearls and shelled pearls.

Selection method of pearls

1, look at the luster

When choosing pearls, check the luster of pearls. When pearls are placed on white soft cloth, they can see the luster similar to seven-color rainbow when facing the light, among which pearls with rich layers and strong reflective luster are of better quality.

Step 2 look at the shape
