QUARTZ CRYSTALS CRYSTAL SKULLS

Quartz crystals come in a huge variety of colors depending on the mineral impurities present within the crystal lattice. In its most pure, natural state, quartz will be clear, but it can be purple (amethyst), brown/black (smoky quartz), pink (rose quartz), green (prase), red, and about every shade in between. Quartz is the second most common mineral on Earth and can form large, spectacular crystals that are highly desirable among both collectors and those just looking for something beautiful to display.
