Pretty twinkly purple aura quartz geode that measures about 8cm x 5.6cm.
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.
