TOURMALINE Natural 1.25 CT 8.02 X 6.53 MM Oval Cut Loose Gemstone 13072839The name tourmaline is derived from the Sinhalese word "turmali." Tourmaline occurs in many single colors and color combinations. Some of the common colors of tourmaline are orange, red, yellow, shades of green, pink, blue, violet, multi-colored and brown. It is also available in black which is opaque and mainly used as pendent and ring stones. Tourmaline mainly comes from Sri Lanka (formerly Ceylon), Madagascar, Tanzania, United States, Brazil, Australia, Afghanistan, Burma, India and Russia Our gemstones are earth mined natural gems. Sri Lanka is one of the leading natural gem producers in the world. You can refer to any popular gemology book such as Gemstones of the World or Simon & Schuster's Guide to Gems and Precious Stones and you will see numerous reference to Sri Lanka as the locality for over 40 varieties of natural gemstones. I was born and raised in Sri Lanka and I have access to these gemstones right from the mining region. I do at least three tests for sapphires - Refractive Index using refractometer and reflective index and thermal sensitivity using Presidium Duo Tester, and at least two tests (or all three tests if in doubt) for other gemstones to verify the authenticity before listing them. I don’t list any stone that I have doubt about the authenticity. And I do not color enhance my pictures so you see pretty much what it looks like in real. As per my buyers’ feedback, some gemstones are actually look better in person. Thank you.
