The clear area glows yellow?
My first thought, on texture, was Cairo Novelty. I have some lightly glowing Cairos but the two in my small set which glow didn't have blue.
My second thought was Heaton, because that's usually my second thought if Cairo is one of the possibilities. And I was pretty sure I had some Heatons -- I KNOW I do -- I GOTTA. But I'm not seeing them where I expected. So can't check that.
So then the next thought was just to wave my blacklight over all my identified swirls. I have some bright glowing coming from my Jacksons -- and one of the glowers has blue and a clear base, but it also has off-white, not white, and it's the off-white which is lighting up.
My Champions got depleted when half of my Champs got turned into Alleys overnight. (They were dug at the Champ site, but the Champ site was right next to the Alley site, and they turned out to be Alleys.) No significant glowers left in my known Champs. (Maybe one with some orange glow.)
No significant glowers in my known Ravenswoods.
Keep in mind I'm working with small samples.
Plenty of glow in my Alleys, but none in my samples which look closest to yours. Not that any look very close, but I do have some Alley with white and blue in clear. Just not sure the texture is that close to yours on the white.
