The new type of tourmaline, which soon became known as Paraiba tourmaline, came in incredibly vivid blues and greens. 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.
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 beautifule sherbet colors of torumaline 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.
