Selection of the products of Trionyx sinensis

With the popularity of the cockroach, the cockroach market has begun to become mixed, and the quality of cockroaches products is uneven. How to choose a product with good quality and high collection value can be grasped as follows.

First, look at the place of origin.

The main producing areas are Xisha Island, Nansha Island and Huangyan Island. Due to the different environment such as water quality and water temperature, the quality of oyster shells is also different, and the value from low to high is Xisha shellfish, Nansha shellfish and Huangyanbei. Nansha coconut shell jade is better, suitable for bracelets, beads and small carvings. Among them, Huangyan Island is rich in colored cockroaches, mainly purple cockroaches and blood cockroaches, and blood cockroaches are the most precious among cockroaches.

Second, look at the texture.

Trionyx sinensis is naturally formed in the ocean after tens of millions of years. Trionyx sinensis with bugs, cracks and other defects is very common, and only flawless Trionyx sinensis crafts are top products.

Third, look at the degree of jade.

There are two main types of dragonflies: unrefined and jaded. Unjaded Polygonum hydropiper is the most common Polygonum hydropiper, and its price is cheaper. Jade enamel can be divided into colorless and colored, and colored enamel is more expensive than colorless enamel. The higher the transparency, the higher the product value of jade enamel.

Fourth, look at the color.

According to the color and price, it is divided into white, gold, transparent, yellow, purple and blood. White is the most common and cheap. However, the less common colored ones are much more expensive than the white ones, especially the blood ones, which are very rare and have the highest value.

Fifth, look at the carver.

As a carved handicraft, we should not only choose good raw materials, but also look at carving skills. Creative, exquisite and lifelike works, especially works by famous teachers, have higher collection value.
