In jewelry, there is a thousand-year-old spiritual thing, which is red coral. People take it out of the sea, make it into handicrafts and jewelry, and let it shine on land. Red coral is exquisite, rich and auspicious, and is naturally loved by people.

Real red coral is porous and has natural texture on the surface. If the surface is very smooth and uniform in color, it looks dull and lifeless, and the texture is particularly obvious, which may be caused by other creatures in the sea.
