A jadeite bangle is a hololith, carved out of a single jadeite boulder. Such jadeite bangles command very high prices because of the of the immense wastage during the carving and polishing process. Another reason that enhances the price of such jadeite bangles, is the fact that such bangles can be carved out only from a jadeite boulder almost entirely free of fissures and inclusions, because the presence of such impurities, can reduce the hardness and consequently the durability of the piece of jewelry created from it. Apart from this, the “Highly Important Jadeite Bangle” also has highly desirable characteristics such as a vivid emerald-green color and very good translucency, two indicators of jadeite of the highest quality. Jadeite bangles of such desirable characteristics are exceptionally rare, that they seldom appear even at international auctions. One such extremely rare jadeite bangle appeared at a Sotheby’s Magnificent Jewels and Jadeite Spring auction in Hong Kong in April 2014, known as a “Guifei” bangle (noble consort bangle) and sold for a record HK$ 43.8 million (US$ 5.6 million), a world auction record for any such Jade bangle. Incidentally, this auction also set the world auction record for any jadeite jewelry of HK$ 214 million (US$ 27.44 million), set by the Cartier’s Hutton-Mdivani Jadeite Bead Necklace.

While one plaque is carved with the Chinese mythical creature, the Dragon, the other matching plaque is carved with the complementary Chinese mythical creature, the Phoenix. The dragon and phoenix are associated with good fortune, wisdom and prosperity. Together they represent a balance of forces, yin and yang, that brings order and harmony to the world. The dragon a symbol of benevolence and power became the symbol of the emperor. The phoenix, a mythical bird and a female symbol came to be associated with the empress. The pairing of dragon and phoenix was regarded as a powerful sign of good fortune, which led to its incorporation into the decorative arts of ancient and traditional China. The symbols painted on household items like a vase, bowl or a jar or carved on ornamental jewels like jade, or incorporated into the design elements of a garden, park or home, connoted a wish for harmony, good fortune and high social status. Being symbolic of a happy and successful marriage, the dragon and phoenix were popular decorations for bridal gifts. They are also the name for “lucky” male-female twins. Most importantly, they embodied the stability of power in dynastic China and the longing for order and balance in Chinese society.
