Hetian jade has the highest hardness, delicate and moist quality, dark color and pure consistency. On the whole, it shows a strong spirit, which means that the foundation will last forever, so it has always been the main material of the national seal.
All the imperial seals handed down from feudal dynasties were made of sapphire. Among the 25 jade seals of the Qing Dynasty, 13 were all made of sapphire, so jade experts all called Hetian sapphire "the jade of emperors".
