Jade Jewelry
Jade refers to two types of very similar minerals, Nephrite
jade and Jadeite which are widely used to make jade jewelry and ornaments.
Nephrite jade is an interwoven network of calcium and a magnesium-iron
rich amphibole mineral series tremolite-ferroactinolite. The more iron
that is present will give it a deeper green appearance and it is slightly
softer than Jadeite. Jadeite is an aluminum and sodium rich pyroxene
that is about the same hardness as quartz. Although it is harder than
Nephrite, it is not as tough and will fracture with less force.
In China, jade is considered to be the imperial gem, and jade jewelry,
armor, ornaments and weapons were common. The most pure white jade was
given to emperors and then fashioned by artists into wearable pieces,
pictorials and pendants. In ancient china jade was considered more valuable
than gold and silver, especially lighter and more translucent jade.
In the long history of the art and culture of the enormous Chinese empire,
jade has always had a very special significance, roughly comparable
with that of gold and diamonds in the West. Jade was used not only for
the finest objects and cult figures, but also in grave furnishings for
high-ranking members of the imperial family.
Jade became a favorite material for the crafting of Chinese scholars
objects, such as rests for calligraphy brushes, jade jewelry as well
as the mouthpieces of some opium pipes due to the belief that breathing
through jade would bestow longevity upon smokers who used such a pipe.
The rarity of jade, coupled with its beautiful color has made it a highly
desirable material for jewelry and other ornaments. Because of its desirability
there have been many other stones that have been dyed and passed off
as jade to tourists or the undiscerning eye.
