Shell, a kind of shell, is named after its purple color. The output is scarce, so it is precious.

The main components of purple shell are 95% calcium carbonate and a small amount of shell. Generally can be divided into three layers. The outermost layer is dark brown cuticle (shell skin), which is thin and transparent and has the function of preventing carbonic acid erosion, and is composed of chitin secreted by the edge of the mantle; The middle layer is prismatic layer (crust), which is thick and consists of prismatic calcite secreted by the mantle edge. The outer layer and the middle layer can enlarge the area of the shell without increasing the thickness. The inner layer is the nacre (bottom layer), which is composed of phyllodes secreted by the whole surface of the mantle. It has a beautiful luster and can be thickened with the growth of the body. In addition, the purple shell is a girl's screen name, a lively girl wrapped in purple.

A century ago, deep-sea purple shellfish was a symbol of luxury and splendor of European aristocrats. It has a crystal-like charming luster and changing colors, but it also has colorful colors different from crystal. Purple pearl oyster, which breeds pearls, has never been ignored and buried for thousands of years. In the late Qing dynasty, mussels and other shellfish were polished into buttons and decorated on high-end clothes in Hangjiahu area. They have always been the best friends cherished by designers. Especially in the past two years, jewelry-grade shellfish ornaments have been more and more loved by people who like handsome and natural in our city.
