'Parti'/tri colored paraiba? (green, blue, pink)

[toomuchB]

This seems to be a rather niche material, so I felt like sharing and hopefully learning something. I cannot afford this material at the quality and size I would want, at least not from the singular seller I found linked below. It goes without saying, any buyer should expect a trustworthy lab report for the origin premium and Paraiba designation. Anyway...

Example from their IG, where there are more of varying quality if you care to look:

I also saw a slice of this material here, from a more familiar vendor.

Has anyone here seen something similar from other vendors or IRL?
Do you consider these true paraibas, considering the tri-color aspect?
Do you think a top lab would designate these as paraiba, considering the tri-color aspect?
I would be happy to read articles, academic or not, on this material. I couldn't find any.

I would only purchase a paraiba based on its neon blue and/or green color, not just because they contain copper in their chemical composition.

That isnt paraiba as far as I'm concerned.

Appreciate your POVs. My gut instinct was the same as yours.

I contacted the dealer and they did half-get a Paraiba designation from GIA on the 0.35ct stone I shared above. The report stated that the 'violetish blue and green portion' may be called Paraiba in the trade, and the 'purplish pink', rubellite.

Then again I think labs are often too lax with these designations (like with super pale cuprian 'paraibas')

I would post the report here but the seller seems quite protective as they deleted the image shortly after I confirmed I was not interesting in purchasing. I conveyed the main info here anyway.

Right now I find the material super beautiful and interesting, whatever the label, but overpriced. I have seen Afghani tri colors online like this one, which may have potential (regardless, not buying anytime soon).

That is a beautiful stone and yes, I completely agree with the bolder statement above.

As far as I know, there is no copper in Afghan tourmaline, but they’re often more beautiful than what labs deem as “paraiba.”

The color range of Paraiba given by GIA: purple，blue，bluish-green，green，yellowish green, but a necessary condition is that the tourmaline contains copper. Peach and pink are not in the color range of Paraiba even with copper
