Jade:
Chinese Stone of Heaven
Since at least 2950 BC, jade has been treasured in China as the royal
gemstone, yu. The character for jade resembles a capital I with a line
across the middle: the top represents the heavens, the bottom the earth,
and the center section, mankind. The word yu is used in Chinese to call
something precious, as in English we use gold. Jade was thought to
preserve the body after death and can be found in emperors' tombs from
thousands of years ago. One tomb contained an entire suit made out of
jade, to assure the physical immortality of its owner. For thousands of
years, jade was a symbol of love and virtue as well as a status symbol.
In Central America, the Olmecs, the Mayans, the Toltecs all also
treasured jade and used it for carvings and masks. The Aztecs instituted
a tax in jade, which unfortunately led to the recycling of earlier
artworks.
The history of jade in Europe is not quite as distinguished. Although
prehistoric axes and blades carved from jade have been found by
archeologists, most Europeans were unfamiliar with jade as a gemstone
for jewelry use until the sixteenth century when jade objects were
imported from China and, later, Central America. The Portuguese, who
brought home jade pieces from their settlement in Canton, China, called
jade piedre de ilharga, or stone of the loins, because they believed it
to be strong medicine for kidney ailments. Jade objects brought back to
Spain from the new world were called by the Spanish version of this
phrase piedra de hijada. This became the French ejade and then, finally,
jade.
The ancient jade carved in China was what we today call nephrite jade:
an amphibolites mineral. (Interestingly enough, the word nephrite comes
from the Greek word for kidney, nephros, a bit more scholarly version of
the same thing.) In the 19th Century , it was discovered that the
material from the new world was not the same mineral as the jade from
China. The mineral from Central America, a pyroxene, was called jadeite
to distinguish it from the original nephrite.
The Chinese knew about jadeite, travelers had brought back some jadeite
from Burma as early as the thirteenth century. But China was turning
inward at that time and this foreign Kingfisher Stone, as they called
it, referring to the brightly colored feathers of the bird, was not
considered to be real jade. It only became popular in the eighteenth and
nineteenth century when trade with Burma opened up again.
Today it is jadeite jade that is considered the real jade, commanding
prices much higher than nephrite because it comes in much more vivid
green colors and finer translucency than nephrite jade. Jadeite jade is
produced in Burma, which is now known as Myanmar. Every year, the
state-owned Myanmar Gems Enterprise holds the Myanmar Gems, Jade, and
Pearl Emporium where boulders are sold by tender to the top jade dealers
from around the world.
Jadeite dealers must be some of the world's biggest gamblers because of
the way they buy. Boulders are sold intact, with only a tiny window cut
in the side to expose a small section of the interior. The buyer has no
idea what lies inside: valuable green jadeite or perhaps only white or
brown-stained inexpensive material. He has only his instinct, and on
that basis he pays hundreds of thousands of dollars for what may turn
out to be the deal of the year or a huge loss.
The top jadeite jade is usually cut into smooth dome shapes called
cabochons. Jadeite bangles are also very popular in Asian countries.
Beads are also very beautiful and some important jadeite necklaces made
during the art deco period have fetched hundreds of thousands of dollars
in auctions in the past few years.
Because of its smooth even texture, jade has long been a preferred
material for carving. The most common shape is the flat donut-shaped
disc called a pi, which is commonly worn as a necklace.
The Emerald Buddha, the sacred image that is enshrined at Wat Phra Kaeo
in Bangkok, Thailand, is actually beautiful green jadeite.
Jadeite jade is most treasured for its vivid greens, but it also comes
in lavender, pink, yellow, and white. Nephrite is found in less intense
dark spinach greens, white, browns, and black.
While jadeite is mined today primarily in Myanmar, small quantities can
be found in Guatemala. Although Neolithic jadeite axes were found in
Europe, it is not known where this prehistoric jadeite was mined,
although it is possible that the material came from a deposit in the
Alps. Nephrite is mined in Canada, Australia, the United States, and
Taiwan.
Jade is most often sold by the piece rather than per carat. Although the
overall color is the most important value factor, attention is also paid
to translucency, texture, and also to pattern. Certain patterns,
including moss in snow, are highly valued.
