The Jeffrey Quarry of Arkansas is justifiably famous for its superb solution Quartz crystals. Gemmy and lustrous almost beyond belief, they are highly sought-after world wide. This specimen is a particularly rich cluster of solution Quartz with a several crystals being doubly-terminated, and all are glassy and gemmy. I think the moniker has to do with the fact the crystals tend to be intergrown with many others in jackstraw groups which are not attached to matrix: the unlikely-looking floater status of these delicate groups thus reflects the fact they were in solution rather than deposited onto country rock. Today, mining of these specimens is done only by (risky) diving using scuba equipment, last I heard. This toenail is mesmerizing and complete all around. Classic US material, hard to find. Better in person.
