A polished fire quartz sphere from Brazil, clear quartz shot through with vivid red and orange. "Fire quartz" is a trade name; what you are holding is hematoid quartz, clear quartz coloured by inclusions of iron oxide (hematite) that formed as iron-rich fluids moved through the crystal. It is the red counterpart to golden healer, the yellow-gold version of the same iron-included quartz. Here is the honest part: most commercial fire quartz, including this piece, is heat treated to deepen and brighten the red. The iron is real and natural; the heat simply intensifies the colour, which is standard for this material and rarely disclosed.
