Bright rainbow collections of gemstone varieties were called "turmali" parcels. Tourmaline, occurring in more colors and combinations of colors than any other gemstone variety, lives up to its name. There is a tourmaline that looks like almost any other gemstone! Many stones in the Russian Crown jewels from the 17th Century once thought to be rubies are actually tourmalines. Perhaps this is why this gemstone is said to encourage artistic intuition: it has many faces and expresses every mood. The Empress Dowager Tz'u Hsi, the last Empress of China, loved pink tourmaline and bought almost a ton of it from the new Himalaya Mine, located a long way from the Middle Country in California. The Himalaya Mine is still producing tourmaline today but the Dowager went to rest eternally on a carved tourmaline pillow. Tourmaline is also of interest to scientists because it changes its electrical charge when heated. It becomes a polarized crystalline magnet and can attract light objects. This property was noticed long ago before science could explain it: in the Netherlands, tourmalines were called "aschentrekkers" because they attracted ashes and could be used to clean pipes! Tourmaline occurs in every color of the rainbow and combinations of two or three colors. Bicolor and tricolor tourmalines, with bands of colors are very popular. Sometimes the colors are at different ends of the crystal and sometimes there is one color in the heart of the crystal and another around the outside. One color combination, pink center with a green rind, is called "watermelon tourmaline" (seedless, of course!) Sometimes designers set slices of the crystal instead of faceted stones to show off this phenomenon. Almost every color of tourmaline can be found in Brazil, especially in Minas Gerais and Bahia. Pink and green colors are particularly popular. In 1989, miners discovered tourmaline unlike any that had ever been seen before. The new type of tourmaline, which soon became known as Paraiba tourmaline, came in incredibly vivid blues and greens. The demand and excitement for this new material, which soon fetched more than $10,000 per carat, earned more respect for the other colors of tourmaline. Pink and green tourmaline are now widely available and are especially popular in designer jewelry. Blue tourmalines are also very much in demand but the supply is more limited. Tourmalines are most often cut in long rectangular shapes because of their long and narrow crystal shape. Tourmaline crystals are beautiful, pencil thin and ridged, and they are also sometimes set in jewelry. Some designers also set rainbows of tourmaline in each color of the spectrum. Tourmaline is strongly pleochroic: the darkest color is always seen looking down the axis of the crystal. In addition to Brazil, tourmaline is also mined in Tanzania, Kenya, Madagascar, Mozambique, Namibia, Afghanistan, Pakistan, Sri Lanka, and California and Maine in the United States. Maine produces beautiful sherbet colors of tourmaline and spectacular minty greens. California is known for perfect pinks, as well as beautiful bicolors. One particularly beautiful variety is chrome tourmaline, a rare type of tourmaline from Tanzania which occurs in a very rich green color caused by chromium, the same element which causes the green in emerald. Tourmaline is a hard and durable gemstone which can withstand years of wear. You might want to avoid steam cleaning or heat. Paraiba Tourmaline: Redefining Blue Neon. Fluorescent. Electric. Peacock. A new gemstone discovered in Brazil in 1989 left gem dealers searching for new adjectives to describe brilliant blue and green tourmalines that are more vivid than any ever seen before. Tourmaline is the world's most colorful gemstone but, until the Paraiba deposit was found, no tourmaline had ever shown the sizzling turquoises, electric blues, rich twilight blues, and neon greens of the new discovery in Paraiba, Brazil. In fact, this color hasn't been seen with any consistency in any gemstone variety. The spectacular colors are due to the presence of a small amount of copper. But a recent study by the German Foundation for Gemstone Research also discovered a surprisingly high gold content. The average gold content of the earth's crust is 0.007 parts per million. Paraiba tourmalines contain a remarkable 8.6 parts per million. If they weren't so beautiful, they might be in danger of being crushed to salvage the gold! The tourmalines are mined near a village called Sao Jose de Batalha in the state of Paraiba, Brazil. The area produced tourmaline for almost ten years but the crystals were too fractured and broken to be cut into gemstones. Then the miners discovered a new vein of gem-quality stones with the extraordinarily bright shades of blue and green. The blues come in sizes up to eight carats and the greens up to twenty carats. The tourmalines are found in a small hill near the village which is being mined laboriously by hand. The hand-excavated shafts and interconnected tunnels are up to 60 meters deep and tourmaline is found only in small pencil-thin veins. Because of the difficulty in mining, the supply will always be limited and the tourmalines will always be rare and expensive. Dealers all over the world - especially in Japan, the world's largest importer of these gemstones - are competing for the new Paraiba tourmaline, which means that it can command retail prices over $20,000 per carat for the finest specimens. Although this is more than other colors of tourmaline, it is very little when you consider how rare these gemstones are. Diamonds are quite common in comparison. Jewelry designers are experimenting with combining the new blue and green Paraiba tourmaline shades together in one piece of jewelry. The turquoise or green colors are also often combined with pink tourmaline for striking two-tone combinations. black jewelry metaphysical tourmaline,tourmaline tank rings,tourmaline pictures,tourmaline himalaya mine,tourmaline tank ring,nigerian paraiba tourmaline,semi-precious beads tourmaline,pink tourmaline briolette beads,seafoam green tourmaline ring,purple red tourmaline,structure tourmaline,copper tourmaline,seafoam tourmaline jewelry,pink tourmaline briolette,watermellon tourmaline,watermelon tourmaline ring,pink tourmaline briolette,tourmaline jewlery,tourmaline bibliography,tourmaline,pink tourmaline,tourmaline beads,green tourmaline pendant,watermelon tourmaline pendants,watermelon tourmaline jewelry,tourmaline sphere,maine tourmaline jewelry,tourmaline specimens,loose pink tourmaline,green tourmaline,watermelon tourmaline,paraiba tourmaline,tourmaline jewelry,pink tourmaline rings,maine tourmaline,black tourmaline,tourmaline ring,tourmaline rings,pink tourmaline ring,tourmaline gemstones,indicolite tourmaline,pink tourmaline earrings,tourmaline bead,tourmaline crystals,birthstone history tourmaline,tourmaline earrings,dark greenish brown tourmaline,tourmaline pendant,ready made tourmaline beads,tourmaline gem stone,blue tourmaline,watermelon tourmaline information,pink tourmaline pendants,neon tourmaline,loose blue green tourmaline,tourmaline noire,yellow tourmaline,pink tourmaline jewelry,green tourmaline jewelry,tourmaline wire wrap pendants,tourmaline pendants,rough tourmaline,tourmaline idaho,tourmaline stones,nigerian paraiba colored tourmaline,pink tourmaline round,blue tourmaline rings,nigerian blue green tourmaline,wholesale nigerian tourmaline,heart shape pink tourmaline diamond rings,pink tourmaline heart enhancer and slides,tourmaline rough,red tourmaline specimen,tourmaline crystal specimens for sale,green tourmaline stone,tumbled black tourmaline,how do you mine tourmaline,tourmaline facet rough,gems tourmaline,tourmaline powder,paraiba tourmaline facts,heart nigerian pink tourmaline,quartz with tourmaline,chrome tourmaline,tourmaline necklace,buy green tourmaline ring,tourmaline designer jewelry,mining of tourmaline,mining tourmaline,tourmaline la jolla,tourmaline ring silver,blue tourmaline loose,hexagon pink tourmaline,pink tourmaline stone,tri color tourmaline,tourmaline mines north carolina,tourmaline brazil
