”
Lustrous, white celestine crystals to 3.0 cm on limestone matrix. The crystals look hexagonal, but are in fact, parallel growth. They are FLUORESCENT and PHOSPHORESCENT! This undamaged piece was collected in the early 1980s by Henry Fisher from the Lime City Quarry and the locality is now closed. this very striking two-toned habit is unusual and was found only a few times around that period.
Origin: Lime City Quarry, Wood Co., Ohio, U.S.A.
Sample size: 11.5 x 9.5 x 6.0 cm”

Here’s her response. Hope it helps.

Mom,

The rock might be beryl, but it is difficult to know. Beryl is usually hexagonal (which these crystals are), but without holding it I can’t know it’s specific gravity or its hardness. Also, beryl typically forms in rocks called pegmatites, and I’m not terribly familiar with the geology of Ohio, so I don’t know if there are any pegmatites in that region. I would suggest the person’s brother takes the rock to a University geology department if he wants a real answer.

Sorry I couldn’t be more help!

Love,
Jenny

I asked a geologist friend and he said it might have failed because of impurities on the surface or in the crystals – frustrating.
