Identity Helphelp with an ID on this fluorescent rock
Found on the lake Michigan shoreline in Milwaukee county WI while out looking for fluorescent rocks the other night. It really caught my attention with how brilliant orange it fluoresces using a long wave filtered 365 flashlight. Same color but not as vibrant or bright under SW.
It looks like a piece of dolostone or some carbonate rock which there is plenty of here but it did not react to dilute HCL.
The hardness is over 7 but under 8, you may be able to see scratch marks from the #8 pick in the 3rd photo, #7 left the streak of the pick and no scratch.
I think Sodalite is a possibility based on strong long wave response and weaker SW repsonse. If you could measure the Specific Gravity that would narrow it down.

It could be quartz rock (yes, orange UV response).It could be chalcedony, there is a lot of it where I found this but none fluoresces like this most of it is more a dull yellowish color. Ill try doing a sg test later today. 
Hi Fuss;
If it is chalcedony then it is quartz.
Also a specific gravity test will probably not work as the void spaces seen on the surface are also likely in the interior of the rock, probably not connected and so, will give you an anomalously lower specific gravity reading. You would have to break off a small piece with no voids to get a chance at an accurate reading.
Another possibility is a silicified carbonate which is why you don't get an HCl reaction. The voids in the sample have a few distinct geometries (semi-circular, lenticular and spherical) which, in carbonate rocks, are leached fossils hence the roughly geometric voids. If you wet the rock and observe under magnification you might also see relic fossil structures.
