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 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.
