Crystallized diopsides (such as diopside in Qinghai jade), hornblende (such as the hornblende in some "black Usha" in Myanmar), etc., also have developed (011) cleavage, and may also have "Cui nature"; microscopic crystal jade pendant generally can not see the "green", so "cade" can not be used as a characteristic mark of natural jade pendant.

These fillings are not considered B goods and are easy to identify. Some jade pendant sellers often use two bracelets to gently hit the crisp "steel" sound to show that it is a natural jade pendant, and the impact of filling the prominent jade pendant B goods is slightly boring.
