A very rare MATRIX specimen of Quartz from Herkimer, perched atop calcite crystals! The quartz measures 5 cm across and floats up there, complete ALL around. And undamaged. Incredible! It is also not repaired, as most matrix specimens are. And most of those are just quartz on ugly gray rock! I grew up in the midwest and collected here as a kid, and I can assure you that one does NOT routinely see a Herkimer-type specimen like this!
