Jade is a name that was applied to ornamental gems that were being brought to Europe from China and Central
America. It wasn't until 1863 that it was realized that Jade was being applied to two different minerals. The two
minerals are both exquisite for the purposes that jade is put to task and are hard to distinguish from each other. So
what to do? Leave it alone and call them both Jade!

Jadeite is almost never found in individual crystals and is composed of microscopic interlocking crystals that
produce a very tough material. Nephrite is actually not a mineral, but a variety of the mineral actinolite. The nephrite
variety is composed of fibrous crystals inter-twinned in a tough compact mass. Other actinolite varieties are quite
different from nephrite.

The toughness of jade is remarkable. It has a strength greater than steel and was put to work by many early
civilizations for axes, knives and weapons. It was later that jade became a symbolic gem used in ornaments and other
religious artifacts during the eons.

Today jade is still valued for its beauty. Its many colors are appreciated, but it's the emerald green color that jadeite
produces so well, that is highly sought after by artwork collectors. This emerald green jade called "Imperial Jade" is
colored by chromium. Other colors are influenced by iron (green and brown) and manganese is thought to produce
the violet colors. Nephrite is usually only green and creamy white, while jadeite can have the full range of jade's
colors.
