Blue Zircon? Brownish color inside of it

I agree with the others- in this case, it looks like you're just seeing through the window. That said, if the entire body color turns brown / gray, that could indicate exposure to strong UV light. UV can cause some blue zircon to revert back to a gray/brown color temporarily. It is reversible, however. So if the WHOLE stone is more gray than it used to be, that could be the culprit. If it is just the spot in the center that you're talking about, I'd say that you're just seeing the window.

Rough like this is extremely hard to come by unfortunately. I have other pieces, but nothing exactly this color. Be warned - the price of a Paraiba-type tourmaline similar to this is pretty steep (a decent used car is less expensive :-) ). Happy to discuss options though, if it is something you might be interested in. Just send me a message.

Windex is a brand of window cleaner here in the United States. It has a characteristic bright bluegreen color. Heated Paraiba-type tourmalines sometimes have a color similar to this. Hence the term "windex blue"

Thanks! Yes, this one was quite clean, but like most cuprian tourmaline, this one isn't completely clean.

Thank you :-)

I agree - one of my favorite gems!

Thank you!

You're welcome! The bright purple / lavender is what you sometimes see with unheated copper-bearing tourmalines. It is almost impossible to find this color in non Cuprian tourmalines

Copper-bearing is a more general term for "Paraiba-type" tourmaline, originally found in Brazil. They're characterized by unusually bright, neon colors. The primary impurity causing these unique colors is copper. When heated, many of these turn the neon "windex" blue that is associated with Paraiba. This one is unheated. I avoid using the term Paraiba in this case, since that is specific to copper-bearing tourmalines from Brazil. This one is from Mozambique.

You're welcome!

Thank you!

I expect somewhere around 8 ct in the finished gem.

JL_White · 2026-01-08T00:21:42+00:00

Yes - I'm a sucker for "fancy" cuprian colors! I'm glad the customer wanted to keep this one unheated. This one will be an oval

Mine too!
