From Daye, Hubei (China) - this is truly unusual piece - it's a double terminated Calcite (how often do you see that?!). Height measurement is with it 'lying down.' The photos capture the texture and point definitions. Real collector's item, and great hand held power piece too!
Semi-Glittery, looks like Celestite - carries that energy as well - "Heavenly Gifts!"
Quite unusual cluster - almost a floater, given the semi-termination on the underside - and the top is a bit 'greener' than it looks in the photo (image 2 seems to capture the hue better). It seems to be a sort of Cactus Druze overlay over Quartz and/or Calcite, but I have since learned that it's a Prehnite.
