Today, tons of jade are mined in British Columbia and shipped to China, where both demand and prices are higher than in western Canada. Most people immediately think of China as the source of jade and jade objects. China has always been an important producer of jade, a leading jade cutting center, jade consumer, and jade market. The only time dominance in these activities moved outside of China was between World War II and the early s.

At that time the Chinese government suppressed jade commerce, and Hong Kong temporarily became the center of jade commerce. Jade jewelry and jade artwork are extremely important in China.

They are mostly found in metamorphic rocks associated with subduction zones. This places most jadeite and nephrite deposits along the margins of current or geologically ancient convergent plate boundaries involving oceanic lithosphere. Jadeite is typically found in rocks that have a higher pressure origin than nephrite. This normally causes a geographic separation of jadeite and nephrite deposits.

From ancient times, much of the prospecting for jade has been done in the steeper parts of drainage basins, where pebble- to boulder-size pieces of rocks are found in stream valleys.

Boulders and pebbles of jade normally have a brown weathering rind that hides their inner beauty and potential value. Prospectors search these valleys looking for jade boulders. Small windows are often cut into the boulders in the field to assess the material's quality and to determine if it is worth the labor of transport.

Jade boulders can be very difficult to transport without damage. Human and animal labor was the only way to transport them historically. Today in some areas that is still the only way to move the boulders to market.

Where economics allow, a helicopter with a basket or sling on a cable will fly in to difficult areas. Workers on the ground will prepare the boulders for lifting, and the helicopter will fly them out.

Some jade is also mined from hard rock deposits. Boulders are sometimes mined from ancient conglomerates , but ophiolite exposures are the most important type of hard rock deposit.

Ophiolites are the metamorphosed rocks of ancient subduction zones, now exposed at the surface by faulting or uplift, followed by exhumation by weathering. Jade is mined from ophiolites by both surface and underground methods. Geographically, much of the world's jade is found around the rim of the Pacific Ocean, where subduction transports large slabs of oceanic lithosphere beneath continents and volcanic island arcs.

Perhaps the most attractive and valuable jade found in the United States is from the area around Jeffrey City and Crooks Gap in Wyoming.

The larger stones that are recovered from mines around the world usually have the opaque outer layer and that small window through which the interior is verified.

Jewelry makers will see the high-quality Jadeite through that window and then have to negotiate based on what they can see.
