What kind of stone is it? a blue/green tourmaline?

[MelodySaw]

I was told it was a Frank Ruebel design, but I searched his web site and find the pendant's center stone is a light blue topaz. This stone is much dark with mainly blue color and little bit of green.
The vendor says it is a PARAIBA. if experts here all believe this could be a paraiba tourmaline then I will send it out to get a report.

This stone measures 10.0mm X 10.0mm X 7.50mm.







Thanks for your helps.

If it is a paraiba tourmaline, and the photos are accurate, it isn't particularly neon, and therefore, I wouldn't pay paraiba prices. It could be "paraiba" topaz too, a coated topaz made to have paraiba color. It could just be a regular tourmaline or cuprian too.

Thanks. I did not pay paraibe price. But If it was a topaz, then I paid a little bit too much.

Based on the colour and size, I'm guessing it is a "Paraiba" topaz, which is a colour coating applied to an irradiated blue topaz to give it the paraiba colouration.

The reason for the higher price is due to the designer name.

It is a little too clean to be a checkerboard cut neon paraiba. Paraiba is rarely cut like that. Especially for such clean material.

Chrono, You are truly AWESOME! Better than Google! I now believe it is a topaz, because it matches the description.

Could it be a blue zircon?

No doubling of the back facets.

That is unfortunate.
