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 dont 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.
