- About Jade -

While there are two kinds of jade "Nephrite" and "Jadeite", "Jadeite" is more valuable.

In China, Jadeite is considered as the most valuable stone.
People believed that having two jadeites in life would bring good fortune.

There is a misunderstanding in the world that "Jade is produced in China", however the fact is that jadeite is produced only in a limited area of Myanmar, Japan, Russia and Guatemala.
The highest quality jadeite is only produced in Myanmar, most especially in Bagan (Pagan) area.

Jadeite is a pyroxene mineral with composition NaAlSi2O6. It is monoclinic.
Needle-formed small crystal fibers are put together closely.
That's why jadeite has high tenacity, therefore experienced skills to polish and sculpture jadeite are required of craftman.

Jadeite has unique resinous luster.
The beautiful green color is thought to derive from chrome, however, there is a still not clear part.

The highest quality Jadeite has high degree of translucency, glassy texture, without spotting or veins, and deep green color that looks even to human eyes.
Some jadeites have violet color called "Lavender jade", which is very popular however bright deep color one is very rare.
High quality red, bule, yellow color Jadeites are also very rare.
