Here are some more information for Jade Jadeite:
Jade is by far, one of the oldest and sought after gemstones on the planet. It is found on nearly every continent and has played an integral role in the shaping of ancient cultures. Today, it is as precious and valuable as it was one thousand years ago.
The gemstone is formed in subduction zones around the globe. Subduction happens when two tectonic plates smash together and overlap. The plate that is forced down takes its minerals into the depths of the Earth, where the temperature and the pressure are right for creating jade. The mineral is then mined. The dangerous task of excavating the gemstone takes place the world over, China, India, New Zealand, Canada, Siberia, North and Central America at one time or another had mines solely for jade.
There are two types of jade: nephrite, from the Greek word nephros, which means "kidney," and jadeite, which is the green type of jade most people are familiar with. Nephrite jade, when pure, is white. Our English word for jade is derived from the Spanish, "piedra de ijada" or loin stone. This correlates to many ancient cultures belief that jade stones helped alleviate the ailments of the loins and kidneys. But it wasn't simply used for crystal therapy. Jade was crafted for weapons, such as spears and axes, but more so as jewelry and ornamentation.
The stone is classified into several categories. Polar Jade is from the Polar mines in northern Canada, Chrome Jade is specked with brilliant traces of green, Chatoyat has a tiger eye like effect in it, Bortyoidal or Bubble Jade, is shaped like clumps of grapes, and Vulcan Jade is covered with a golden brown skin, found exclusively in California.
The art of jade polishing has been practiced for thousands of years. The mineral is harder than steel and cannot be sculpted; rather, it is ground and then polished to create the beautiful beads and designs we have come to appreciate. The initial grounding of jade is done wet. The stone must be submerged when ground; it gives off a harmful dust that is comparable to asbestoses. A diamond or silicone carbide is used to do the grounding. When the grinding has reached the artists ideal "grit," it is polished using techniques and compounds that are guarded closely by the artist. This technique has been passed down through the generations and has helped create some of the most appeasing designs known to human eyes.
It might not be plausible and affordable for you to own jade jewelry. But there are alternatives. Faux jade is an acceptable substitute to the outrageously priced gemstone. If purchased from a wholesaler, jade beads and pendants can be used to create precious jewelry such as necklaces and bracelets. Craftwork is a soothing process and is a hobby that can be readily displayed. With faux jade there's no reason to hesitate on experimentation, creating whatever you can imagine.
Jade is still used today to create art that is ubiquitously loved and praised for its elegance and wonder. Most recently it was used to help design the 2008 Summer Olympic medals; the first non-metallic to ever be used. Jade is one of the few gemstones to be held with the same loft that it was thousands of years ago. Its beauty is renowned and desired across the globe.

How The Formation Of Fine Jade
How the formation of fine jade
Jade is customary, also known as Myanmar jade, jadeite produced in Burma, Japan, the Soviet Union, Mexico, California, Deng Jun births jadeite, but quality and output is far less than Myanmar.
Area north of Myitkyina in Myanmar, the largest emerald deposit reserves, a very early stage jade mining china gemstone wholesaler, supplies around the world. So people a long time before Burma produced only know jade, jadeite therefore as a synonym for Myanmar jade, and jadeite is the scientific name, and the Burmese jade is the expert jargon.
Jade is how it formed? There are many magical folk legend; geologist've been referring to it as a mystery, it has been considered as emerald and diamond, are deep in the crust several thousand degree heat and high pressure conditions, crystal formation, it is not true; the United States many Geophysicists have done a lot of simulation experiments in the laboratory, combined with jade deposits found around the world, the actual situation, they believe that jade is not formed under high temperature conditions, but in the ─ under the condition of high pressure low temperature Deteriorating causes.
The Government of Myanmar jade auction held every year, attracted many buyers.
Tohoku University, Professor Ichiro Sunagawa, "saying the stones" (1983) was published a book, more specifically pointed out that the jade was 10 000 at atmospheric pressure and low temperature (200-300oC) formed. We know china Jewelry wholesale to the deep Earth from the surface, The depth of the more higher the temperature, the greater the pressure. But Jade is under high pressure at low temperature crystallization, of course, impossible in the deeper part, then the pressure really come from?
This pressure is due to crustal movements caused by the formation of extrusion pressure, has now been confirmed that the distribution where there are emerald deposits in the region, are more intense crustal movement zone.
There is another factor: the formation of any place where jade found both sodium feldspar igneous intrusion (in ─ basic rock). The chemical composition of albite as NaAlSi3O8, it can be speculated china Jewelry wholesale ─ Jade is in the low temperature and high pressure conditions, sodium feldspar from the silicon to the role of the rock formed.

What kind of material is used to cut and shape Jadeite?
I've read that Jade is harder than steel and cannot be cut easily. The Jade is shaped and cut only by a material which is even HARDER, but I don't know what Material, Can someone tell me?
High carbon or tungsten steel will mark it but best to use electroplated diamond mounted bits or aluminium oxide grinding stones to shape and carve it. To polish use various grades of abrasive papers and stainless steel polishing compounds. But note best to use abrasive rather than percussive methods as the stone can fracture if struck.
The other ethical decision is that the best Jadeite comes from Burma or Myanmar a repressive dictatorship.
