Gem Related Discussion

How common are “neon” gemstones in stones like chrysoberyls or zircons? Is there any objective criteria to assessing whether a so-called neon stone is in fact neon? (Would GIA describe a gem as “neon”?). Or is it a case of “beauty is in the eye of the beholder” especially under favorable lighting?

Neon blue. Or bluish green are always vivid color and some samples translucent to opaque and variation of quantity of cooper and manganese and gold (some times ) big variation intense ,vivid or deep to light neon blue all colors are particularly different from all kind of blue but all looks like have a lamp turned on very weak to strong it is amazing stone ![image|375x500](upload://ubSKHtCJdI AjHRt87xcIvcH52wz.jpeg)

Yup, looks neon to me. It’s a pretty stone. What kind is it?

Maybe a Neon apatite

Very probably Paraiba. São José da Batalha Mine. I have one similar, gift from the mine owner.
My shop is actually closed, due to quarantaine, cannot provide a photo now.
I’m quite sure the multicolor specimen in the top photos is also Paraiba.

Neon is not a color, so GIA would probably not describe it as such. In fact, GIA does not mention the saturation (neon would be vivid saturation) or tone (how light or dark it is) in their reports. Tourmalines and apatites are the most common neon stones. Note a stone can be vivid, but not really neon, for example sapphires. It would be interesting to actually hear GIA’s opinion on the subject.
