Here are aura crystals. Yes, they're a real quartz crystal, just ask the crystal bible! They are quartz crystals with a titanium finish which gives them an aurora borealis effect.
These are specifically "crystal points." I make all sorts of things with rose quartz and other crystals, but they are usually in polished or faceted bead style.
Aura crystals have their own energies, but they're not for everyone. Or so I'm told.
