Jade is an umbrella term that encompasses a variety of gemstones, but the only pure forms of jade are jadeite and nephrite. The history of jade goes back several thousand years when jade was first used to make weapons and tools because of its toughness. The Mayans and Aztecs regarded jade highly and the name "jade" originates from the Spanish "piedra de ijada", meaning "stone for the pain in the side". It was named in this way after Spanish explorers saw natives of Central America holding pieces of jade to their sides, believing that it could cure ills. The Chinese refer to jade as "yu", which means "heavenly" or "imperial". Therefore, it is considered to be the imperial gem in Chinese culture. In China, jade was found in the tombs of Shang kings. Jade also plays a part in the history of New Zealand. It is found on the South Island and has been treasured for many years by the Maoris of New Zealand, who call it "pounamu", "greenstone" or "New Zealand jade". Pounamu has been made into Maori tools, such as chisels and fish hooks, and weapons, such as short clubs and ornaments. This New Zealand jade is usually nephrite.
The most reliable method of identifying jade from other substances is by testing its specific gravity. A simple test to distinguish jadeite from nephrite is a chime test. Nephrite emits a musical tone when it is struck, whereas jadeite does not. The main source of jadeite is Myanmar (Burma), which is also the only source of imperial jadeite. Jadeite is also found in Japan, Canada, Guatemala, Kazakhstan, Russia, Turkey, Cuba and the USA. It occurs in green, white, orange, yellow, lavender, grey and black. The most highly valued jade is a vivid emerald green and is semi-transparent. It is known as imperial jade and only occurs in Burma (Myanmar). Jade can be more than one colour in a single gem. Jade in which the colour is evenly distributed is highly valued. However, colour preferences vary depending on the region. For example, in the West, deep and vivid green jade is preferred, but in the Far East, pure white or yellow jade with a pink tone is prized, along with green imperial jade.
Jade lustre is vitreous (glassy). When polished it appears vitreous to oily. Jadeite is said to have a more vitreous (glassy) lustre than nephrite which has a more resinous (oily) lustre. Jade is extremely versatile and is can be carved into intricate shapes. It is carved into a variety of traditional Chinese figures, such as Buddhas, dogs, dragons, bats, butterflies, peaches and discs.
It is also made into all manner of practical items, such as buttons, cups, plates and salt and pepper pots. Jade is used to make beautiful ornaments and is also fashioned into beads, cabochons for rings, brooches and fancy pendants.
Entire bangles are also fashioned from jade. Most jade is cut in Taiwan, China and Hong Kong. Rough jade is often bought as slices, which show no indication of the quality of the material inside. The quality of the jade inside is not known until the rough stone is cut. Jade is often bleached with acid to remove brown pigments.
According to the system, grade A jadeite is not dyed nor impregnated but may have received a coating, which is considered stable. Grade B jadeite may have been impregnated and bleached but is not dyed. Grade C jadeite is dyed and impregnated, and grade D jadeite is not real jadeite.
