A polished fire quartz sphere from Brazil, milky quartz threaded with bright red-orange. The name is a trade term; geologically this is iron-included quartz, the same family as golden healer and red hematoid quartz. Its colour comes from hematite, an iron oxide, trapped inside the quartz as it grew. Most commercial fire quartz on the market, this piece included, has been heat treated to bring the red out more vividly. The inclusions themselves are natural iron; heating deepens their colour, a common step for this material that sellers seldom mention.
