1. Seawater pearls or freshwater pearls are collectively classified according to the culture environment, and then according to the geographical sea area or culture points of the culture, we usually hear the specific classification of pearls.

Seawater pearl classification: Akoya pearl, Ma Bei, Tahiti black pearl, Ao Bai, Nanyang gold pearl.

Classification of Freshwater Beads: seedless Freshwater Beads, seedless "Freshwater Akoya", Edison Pearl (mainly white, purple and gold)

2. Seen from the number of pearls cultivated: seawater pearls are all implanted in round nuclei for pearl cultivation. Generally, one pearl is cultivated for each mother shell; Freshwater pearls, seedless, are usually implanted with more than 20 cells at a time and sliced into mother shellfish for pearl cultivation. More than 20 fresh water pearls can be cultivated at a time. The cultivation of Edison pearls and seawater pearls is the same, one shell one pearl.

There is a great difference between the color and luster of a pearl.

Compared with fresh water Akoya pearls, the gloss of seawater pearls is more natural and comfortable, and the intuitive feeling of texture is much better than fresh water Akoya pearls. Seawater Akoya has a wide variety of colors (white, white powder, champagne gold, golden yellow and gray), while fresh water Akoya generally only has two colors: white and white powder.

Nanyang bead compared with Edison, in addition to nanyang bead colour and lustre is rich, nanyang bead jewelry texture will be much better than Edison pearls, nanyang beads, after all, is a natural gem stone color and luster is without thought processing, and Edison is a product of natural and artificial processing to late, although luster will be more bright but also lack the natural charm of natural stone.

4. Compared with the survival rate of seawater and freshwater pearls, the pearly formation rate of seawater pearls is about 35%, and that of freshwater pearls is more than 60%

5. Seawater pearls are cultured in the sea, while freshwater pearls can be cultured in lakes or by digging ponds by themselves.

6. For those who like purple pearls, we can intuitively compare the peacock purple in Tahiti black pearls and the demon purple in Edison pearls. Although they both look purple in appearance, the difference can be answered with intuitive feelings. The color and luster of Tahiti black pearls look more comfortable and natural. Although the color and luster of Edison pearls look more transparent and bright, they lack the natural comfort of Tahiti black pearls.
