Buy Natural Bi-color Ametrine from Bolivia: Untreated Gemstones fr...

Amethyst and citrine are both forms of transparent quartz and are often found in the same location. Natural golden citrine is considered to be rarer than purple amethyst, and so it usually is more valuable. However, a very rare combination of both colors of quartz found in the same crystal is even rarer than golden citrine. Virtually all the world's supply of ametrine comes from a single mine in Southeastern Bolivia, known as the Anahi mine. Ametrine from Bolivia is considered by most to be the finest quality ametrine available today.

was just windowshopping and spotted a couple "Very Uncommons", a tsavorite & a demantoid garnet that were both in a size I was looking for, & that I could very easily pay for -- so figured I would grab the tsavo ASAP and got the demantoid to accompany so they wouldn't be lonely.

I was looking for ammolite for my husband. Other websites are not always clear about whether they have genuine ammolite or simulated ammolite. I have purchased from GemSelect before and trust that the stones are genuine. Finding the stones I want is easy, and I love all of the search filter options!
