Jade in B.C.
Jade is a commercial term encompassing green, white, black or yellow-brown jadeite and nephrite. Jadeitite is a rock that consists essentially of jadeite (sodium-rich, high-pressure pyroxene), whereas nephrite consists of prismatic to acicular amphiboles of the tremolite-actinolite series forming bundles that are randomly oriented and interlocked. All of the known jade deposits in B.C. are of the nephrite variety.
Jade has been used since Neolithic times for jewelry and tool making. Today, the best material is used as gemstones. Large quantities are used for carving and ornamental stone or for table tops. Industrial grade material is used for tile making.
Geology and Origin
Nephrite occurs at over fifty sites in B.C. in bedrock, boulder fields and talus. The bedrock occurrences are typically lens shaped and occur at or near contacts of mafic-ultramafic rocks (mainly serpentinite) with metasedimentary or igneous felsic rocks.
Nephrite formed by metasomatic exchange between ultramafic and silica-bearing rocks within the Mississippian to Jurassic age oceanic Cache Creek and Slide Mountain terranes of B.C.
High pressure blueschist or eclogite grade metamorphic rocks, favourable for jadeitite exploration, are found in the Bridge River, Pinchi Lake, Dease Lake and Jennings River areas of B.C.
Known jade mineral occurrences are documented in the B.C. Geological Survey's MINFILE database which is available on the Ministry's website at www.em.gov.bc.ca/mining/geolsurv/minfile

Jade Slabs

Magnetite Jade Slabs
Magnetite Jade has magnetite crystals in the dark to black jade base. This makes magnetite jade a beautiful and unusual stone. Once a cabochon is cut from this material, the magnetite portion can be gold plated, which makes for an outstanding gem.
Jade has been revered for thousands of years in both the Orient and the New World. Although jade has a reputation of being hard to polish, it polishes well with diamond and takes a high polish with chrome oxide. We've found that 14,000 grit Superpolish polishes jade in a snap. We sell this fantastic diamond compound on the polishes page of our Cabbingmachines.com website.
Purple Nephrite Jade Slabs
Purple is a rare color for jade. This nephrite material is from Turkey. It cuts and polishes like agate. Polishes best with diamond or chrome oxide.
Black Nephrite Jade Slabs
Black Nephrite Jade is uniformly colored. When viewed in very bright light a slight greenish undertone can sometimes be detected. This material makes good black jade stones.

JADE FEVER
Co-authored with BC geologist Stan Leaming, this is an important personal record of how the jade industry began in the early 1960s and grew to be the largest in the world by the late 1980s. The book also covers other jade sites in North America, and takes the reader on a series of expeditions to remote jade sites around the world -- Labrador, western China, Siberia, Taiwan, south New Zealand and more.
