Anyone heard and familiar with this BIG labs? Big Mike's Independent Gemological Laboratory, or something to that extent, Japur or Jakarta iirc.

So far I've seen about a dozen reports, nice looking, but BS! No treatments on obviously heated stones. Color Change Alexandrite Chrysoberyl on a stone that shifted at best from a yellow to a brownish greenish yellow deemed Alexandrite due to iron and chromium lines in spectroscope. Just for a few examples. But while they look great they seem to be full of false or misrepresented or mis-ID'ed materials/information.

Any info would be greatly appreciated, thanks you.
