Gorgeous flat rainbow aura quartz geode that measures about 7.5cm x 6cm.
Please look closely at the photos before you buy. aura quartz is a natural quartz crystal that has been permanently treated either by fusing titanium and niobium to it in a vaccuum or sometimes the colours come from a dye that has been fused to the surface of the quartz in a similar way.
Please be aware that these lovely geodes initially can leave a bit of grubby dust on the fingers.
