I'm glad we can do Gemology sitting down. It would probably only take about a week in Vegas before some goon was breaking my legs. :lol:

Actually, there are a lot of GIA people here. You can find them at the AGS headquarters over on West Sahara Ave.
I just staked out the strip for myself before they got here!

The better Brazilian material (not all), if you've seen it has a luminosity that African material does not share. The term first used was electric and later neon. The African material does resemble the non - neon Brazilian Paraiba.

I use the term day-glo sometimes to distinguish it from highly refractive fully saturated well cut gems that are understandably described as electric and neon.

Also, some of the windex blue neon and non-neon Brazilian Paraiba is not heat treated. I say this with certainty as I have both certed.

My personal pet peeve is the way the term Padaparadscha is thrown around. I've never seen a stone that tested Pad that wasn't from Ceylon.

I asked if anyone had a non Ceylon stone test Pad somewhere on the board but I forgot where. I'd sure like to know and see the proof.



I have a stone that tested as pad from GIT (same standards as AGTA) and is from Burma. Color is the most perfect padparadsha.

I have never seen a true pad from Africa but several from Burma and Vietnam. Of course they get sold as Ceylon most usually.

How is the stone tested to be a Pad or not? I just thought it was a matter of being a sapphire, from SL, and of the right amounts of red and orange (which is supposedly subjective).
