“Rainbow Quartz”…. At least that’s what the seller is selling this as. It’s polished Quartz that they have exposed to extreme heat, and then below freezing temps to make the crystals crack…. All to just get rainbows showing in the pieces. Honestly it’s quite sad that humans have gone this far of purposely flawing crystals to get rainbows to show inside of their crystals…. I would love to hear what your thoughts are on this product. Please comment below and share your opinion.
