SCIENTIFIC INFORMATION: Tremolite is a calcium, magnesium and iron silicate. When the iron content is high, it is called actinolite. The chemistry is Ca2(mg,Fe)5Si8O22(OH)2. The streak is colorless, although the mineral itself can range in color from white to dark grey, yellowish, pink to lilac. We commonly tend to think of "jade" as green, but as you can see, it is actually available in many colors. The hardness is between 5 and 6.
ENVIRONMENT: Tremolite is a product of metamorphism and occurs with calcite and grossular in hornfels of contact metamorphic rocks and with talc in serpentinites of hydrothermal metamorphic rocks.
OCCURRENCE: There are many localities where fine tremolite specimens may be obtained. Crystals of up to 3" in length occur in marble at Haliburton and Wilberforce, Haliburton Co., Ontario and granular masses of pink tremolite (hexagonite) at De Kalb, St. Lawerence Co., New York. White and greenish crystals occur in calcite at Canaan, Litchfield Co., Connecticut.
GEMSTONE DATA: The Amphibole mineral nephrite, which consists of combined tremolite and actinolite, is dense, compact, tough. Semitransparent to translucent varieties of nephrite are called [jade.] Nephrite jade colors are white, all shades of green, gray, grayish (with tinge of blue, red, or green), brown, and lavender. Value increases with transparency, intensity and evenness of color, and freedom from flaws. Jade is fashioned into beads, earrings, and cabochons for rings and brooches, or carved into ornamental or religious objects. Nephrite jade comes from Alaska, British Columbia, Wyoming, China and Siberia.
NAME: Tremolite is from the occurrence in Val Tremolo in the Swiss Alps. The word 'jade' is derived from the Spanish [pietra d'ijada] which means 'colic stone'. In China, where jade has been venerated for thousands of years, over a hundred different names are in use for different color varieties.
LEGEND and LORE: Jade ornaments and implements of great antiquity have been discovered both in those parts of the world in which the mineral is found and in places far distant from these. It is the 'greenstone' so highly esteemed by the Maoris of New Zealand who carved it into pendants, sometimes representing their hero Tiki, and into chieftains' war clubs. It has been carved in Central America for well over a thousand years and the ancient Mayas prized it above gold. In ancient China a prospective bride would present her betrothed a jade butterfly to seal their engagement. Likewise the bridegroom would give his sweetheart a gift of jade before their wedding.
MAGICAL PROPERTIES: Jade is considered one of the most important symbols of purity and serenity. It is also revered as an ancient symbol of love. The Maoris regard Jade as a stone that brings luck, especially specimens that are dark olive-green in color. The ancient Chinese felt that Jade helps to inspire the mind to make quick and precise decisions. The ancient trader would often hold this gem in the palm of his right hand while he engaged in business transactions. Carved into a scarab, Jade is said to bring its owner a long and prosperous life. It is also said that wearing Jade while gardening will improve the health of the plants. Similarly, small pieces of Jade can be buried along the perimeter for this purpose. It is worn for protection during defensive magical workings.
HEALING: Jade has been called "colic stone", "spleen stone" and "stone of the loins". It is said that by tying jade to the arm, stones in the kidneys can be expelled. The ancient Greeks used this mineral for healing ailments of the eyes. Wearing Jade helps the body to heal itself while working on the underlying, nonphysical problems which cause the disease in the first place
