ROCK TRIVIA: TOURMALINE ( stone of October )
Tourmaline has a variety of colors.from blues and greens, to reds, yellows and pinks.Gem and specimen tourmaline is mined chiefly in Brazil and Africa.
Almost every color of tourmaline is found in Brazil, including a new colored variety of tourmaline was found in the state of Paraíba It is blue and green. A recent discovery in Mozambique has colors a bit less bright than the Brazilian material, but it tends to be clearer and larger than that found in Brazil.
Some fine gem quality material has been produced in the United States, During the early 1900s, Maine and California were the world's largest producers of gem tourmalines. Typically the colors are raspberry reds and bright pinks and mid-range greens as well as some bicolor in California.
Chrome tourmaline, found in Tanzania. is a rich green color due to the presence of chromium which also produces the green of emeralds.
Top quality indicolite (blue )and verdelite (green) are found in Afghanistan.These tourmalines have beautiful clarity and very intense color.
Pictured is an incredible specimen of Watermelon Tourmaline. This type of Tourmaline may be green at one end and pink at the other or green on the outside and pink inside.
