Jade has been culturally significant to the Chinese for thousands of years. It was a symbol for the worship of heaven and earth. It was seen to embody beauty, righteousness and knowledge. Known as the ‘stone of heaven’, it was considered pure and enduring enough to inspire the highest spiritual aspirations in the wearer. When Emperor Qin Shi Huang brought together the six warring states and unified China in 221B.C., he chose the famous He Shi Bi jade for his Imperial Seal, inscribed with the words: ‘Having received the Mandate from Heaven, may (the Emperor) lead a long and prosperous life.’
For 2,000 years, the stone known as jade was actually nephrite, which was indigenous to China. Jadeite was only introduced to the empire during the Qing dynasty, when traders began exporting it from Burma in 1784. By the 19th century, Burmese jadeite had become the most highly prized gemstone of the Manchu aristocracy. It was the favourite of Empress Dowager Cixi, who loved its bright, vivid colours — it had finally reached pre-eminence as the Imperial Stone, the most precious object in China.
Today, jadeite is still highly coveted by the Chinese as well as collectors around the world. It can be found in a variety of colours, such as lavender, yellow, russet-brown and black, but it is the green stone containing chromium that is the most cherished. The value of jadeite is based upon three important criteria: colour, translucency and texture. Source: christies.com
