In the 1500s, a Spanish conquistador found green tourmaline in Brazilwhich he mistook for emerald.His error held until the 1800s, when mineralogists finally identified tourmaline as its own mineral species. Variations of the name schorl may have been used to describe black tourmaline even before 1400. The name comes from a village in Saxony, Germany, (now called Zschorlau) near a mine with black tourmaline deposits. The Dutch East India Company brought Sri Lankan tourmaline to Europe for centuries before traders realized it was the same mineral as schorl. American tourmaline deposits caused the gemstones spike in popularity. In the early 1890s, tourmaline was reported in Californiawhere Native Americans had, for centuries, given certain colors of the gemstone as funeral gifts. At that point, China represented the biggest market for tourmaline.
The Chinese market was so critical to tourmaline, in fact, that when the Chinese government collapsed in 1912, it took tourmaline trade down with it. Brazilian tourmaline discoveries in the 1980s and 90s reignited interest in this gemstone, because material mined in Paraíba displayed such striking neon greens, radiant blues, and vivid violets. This region has produced the worlds finest, most valuable specimens of tourmalineincluding the worlds largest, weighing 191.87 carats. While plenty of tourmaline is mined around the world, its rare to find fine gem-quality tourmaline in bright colors. This range of material means that the price of tourmaline can vary almost as much as the color.No two tourmaline gemstones are exactly alike, which makes this a one-of-a-kind gift for any individualespecially someone celebrating an October birthday or an eighth wedding anniversary. With a wide variety of colors, qualities, and sources available, theres tourmaline to suit a range of styles and budgets. Like diamonds, tourmaline is evaluated by the criteria of: color, clarity, cut, and carat weight.
Color In general, darker toned tourmaline that appears black is priced lower than brightly colored material. Rubellite tourmaline, in shades of pink or red, is one of this gemstones most desirable colors.
Green and blue tourmaline are also popular, though the most striking shades of these colors come from Brazils exotic and rare Paraíba tourmaline. Clarity Inclusions are common in tourmaline, because liquid inclusions and crystals can get trapped during formation. Its not uncommon for red or pink tourmaline to display visible inclusions, but inclusions can lower the value of other colors, depending on their visual impact.
Some tourmaline material, especially rubellite, undergoes heat treatment to improve color. Other tourmaline is clarity-enhanced to remove inclusions, which can significantly lower the value.
Cut Because tourmaline forms in slender, columnar crystals, many finished gemstones have long, irregular shapes. Tourmalines tend to absorb light differently down the length of a crystal, versus than across it.This optical property is called pleochroism, which means they appear different colors from different directionsso the cut is critical. Carat Weight Tourmaline can come in a range of sizes, but Paraíba tourmaline is rare in sizes larger than one carat.
But with these stones, color is more highly valued than size, so a small, brightly colored gemstone is preferred over a large, dark one. With such a wide range of tourmaline options availablefrom the common, inexpensive schorl to the highly-valued Paraíbathe price of these gemstones can vary greatly.The item "Loose Parcel of Natural Paraiba Blue Neon Tourmaline 2.19 Carats" is in sale since Wednesday, May 6, 2020.
