Seawater pearls are usually regarded as a symbol of high quality because of their large, round, full and few defects, so they are of high value. From the perspective of value preservation, the value of seawater beads is generally higher than that of freshwater beads.

Seawater pearls are rich in color, including white, gold, black and silver. Most seawater pearls are 3 ~ 5 mm in diameter, but pearls with a diameter of more than 8 mm are very rare and of high value.

China's seawater pearls are mainly produced in Beibu Gulf and southeast coastal areas, and Hepu Pearl in Guangxi is the most famous in history. The international evaluation of seawater pearls is very high, and it is considered that their quality exceeds that of pearls in other regions.

The common shape of seawater pearls is a perfect circle, which is also the most ideal pearl shape.
