What kind of gemstone is this? Where would the best place be to find one and approximate price range?

My guess is tourmaline?
Sorry I can't help on vendor rec and price though.

Thanks! I thought it might be tourmaline but wasn’t sure.

Looks like an Afghan tourmaline. They’re often a pretty pastel color, and in blue-green.

Google “Afghan tourmaline” and see what’s out there. They can be $200 to over $1k/carat depending on size, color, cut.

Not to hijack thread but is the indicolite tourmaline with this open c axis/dichroic effect desirable or more expensive?

I’m not sure that’s open color, because the edges are darker. It could have been cut so that the dark “closed” axis doesn’t align with the table. You also have to be careful because tourmaline needs to be viewed in various light sources. That stone could close up and become very dark in sunlight for example. I had such a tourmaline, that color, but it only looked “open” indoors. I returned it, as it was overpriced in my mind for the color.

Typically open, bright, saturated colors are more expensive, but that doesn’t mean some dealers won’t upcharge for any blue-green stone. The prices of regular blue green tourmaline has gone through the roof since paraibas (copper bearing neon blue green stones) have been found, so be careful

I do own an indicolite with a closed axis, but it always looks open in any lighting. It’s beautiful. The material needs to be evaluated in various light sources, but a tourmaline with both open axes, should not close up ever, although it can be slightly grayer or color shift in some lighting.

In my opinion, I would pay a higher price per carat for the stone at the top of this thread. It looks more saturated, even though it’s a different hue and tone.

Agreed... it appears to be some sort of mint or blue-green tourmaline. Good luck in your hunt!
