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:

Example from their site with details:
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.
