I should have mentioned Autunite is listed for this locality, Calcite and Opal are not. I should have it's radioactivity checked.

This is almost certainly Opal-AN, as Reiner and Don suggested.

Is your quartz crystal from the East Morris Dam quarry pit? A number of large smokey quartz crystals have come from there and there significant uranium minerals in that area. Most of it is carnotite, but I see no reason that others that fluoresce would not be there also.

Little or nothing has been written about this quarry other than a few lists in guidebooks or club bulletins without supporting data. Even the bedrock quadrangle map done by Gates in 1951 does not show the Nonewaug (aka Woodbury) Granite extending into the hill where the quarry is (which is shown by the topo lines) even though it clearly does (he shows it nearby though). The accompanying text gives only a general description of the petrology and mineralogy of this formation, with no mention of uranium minerals. As far as I know, carnotite in Connecticut is restricted to the sandstones of the Hartford basin, well documented at the Old Newgate Mine in East Granby.
