The process for identifying a manmade crystal varies greatly from stone to stone.. Crystals are made to be perfectly imperfect. If the crystal in question has zero noticeable flaws or irregularities and is completely uniform in color and pigmentation, it is most likely fake. Glass has bubbles, crystals do not (especially in reference to quartz). Fruit names = fake (lemon quartz, strawberry quartz, etc.). “Aura” indicates a heating and metallic bonding process that changes the molecular structure of the crystal, effectively diminishing or compromising its metaphysical and healing properties. Just like knock-off designer bags sold on Canal Street, price is a huge indication of a crystal’s authenticity. If it seems too good to be true, it probably is.
