Il y a un mois, je suis allee au Cafe Parlez de FAA.
This is an eye-opening experience.
According to Jacky, the host of Cafe Parlez, the Chinese refers the term Jade to quite a large variety of gemstone especially when we talk about "古玉".
To him, Jade means Jadeite, a mineral with composition NaAlSi2O6 excluding Nephrite from the Jade family. When we turn the pages of the catalog of the auction company, we can read the name Jadeite. This is quite different from what we know but Jadeite is really a beauty.
I just love to those with a high degree of translucence and it is called 冰種.
