What is the difference between Nanyang Jade and Hetian Jade?

Composition, Nanyang jade is an altered gabbro mainly composed of calcium and aluminum silicate, and the content of septic stone in Hetian jade is more than 95%; structure, Nanyang jade is mostly dense cryptic structure, and Hetian jade is mainly variable crystal structure; crystal, Nanyang jade crystals are mainly fine-grained crystals, and Hetian jade crystals are often long columns, fibrous, and leaf-shaped.

1. Ingredients

Nanyang Jade

The composition of Nanyang jade is different from that of Hetian jade. Nanyang jade has only one mineral element, and it is an "altered gabbro" containing multiple mineral elements, mainly calcium and aluminum silicate. Hetian jade belongs to the category of septic jade, and the content of septic stone in it is above 95%.

2. Structure

Hetian Jade

Nanyang jade and Hetian jade have different structures. Nanyang jade is mostly dense and cryptic structure, and sometimes it is block, strip, and patch-like structure. Hetian jade mainly has variable crystal structure, including block structure and sheet structure, of which block structure is the most common.

3. Crystal

Nanyang Jade

The crystals of Nanyang jade and Hetian jade are different. The crystals of Nanyang jade are mainly fine-grained crystals, and the particles are relatively fine, and the texture appears hard and dense. Hetian jade belongs to the monoclinic crystal system, and the crystals are often in the shape of long columns, fibres, and blades.
