When it comes to genuine jade, there are two types: 𝐉𝐚𝐝𝐞𝐢𝐭𝐞 and 𝐍𝐞𝐩𝐡𝐫𝐢𝐭𝐞.
Jadeite is much rarer and is commercially available only from Myanmar (Burma). It has higher hardness and is more durable. Moreover, Myanmar is the source of nearly all of the world's finest jadeite.

Nephrite, on the other hand, is less lustrous and almost always opaque. The finest source of Jadeite Jade in the world comes from Kachin state, Myanmar (Burma). It's also the only commercial source for Jadeite in the world. Other small deposits are found in Kazakhstan, Russia, Japan, Guatemala, and USA. Natural Jadeite comes in various qualities and colors.
Due to the high demand for premium Jadeite, industry experts often treat lower quality Jadeite to artificially enhance its transparency and color.
However, these treatments are not permanent and can affect the stone's overall durability.
The enhanced appearance can deteriorate over time, with color-dyed Jadeite typically losing its color when exposed to sunlight for extended periods. Depending on the extent of the treatment, the value of Jadeite can drop dramatically, unlike untreated Jadeite, which appreciates over time.

There are classified into five categories on the Natural Jadeite Jade, from A to D.
