Jade

~The jewel highly valued from ancient times at the Orient~

A beautiful stone is called "gyoku" in China and it's valued. Especially, Jade is highly valued. Even if I point at jade then saying "gyoku", it isn't exaggerated.

The jade is tough because of the organization of a small crystal which interlocked complicatedly inside, and it's difficult to break, and processing is difficult also, on the other hand, it's also the very good sculpture material.

Jade was being used as the material of the sculpture for more than 3000 years in China. Their technology for carving may probably be called the world best.

The chain which seamlessly engraved. The design which is so delicate. The expressive power of which I can't think as a stone. There are Chinese jade carvings can't be easily seen in Japan.
