Clear Quartz: crystal cluster (Brazil) - pair

Pair of clusters of Clear Quartz. Nice clear clusters of single and double terminated crystals, with only small amounts of visible groundmass. Lots of sparkly terminations, and some nice seed crystals and druse. Useful for charging water filter jugs - one week on; one week off to recharge in sunlight, swapping them out; or for gridding or charging small spaces.
