These photos are appalling. It should be a violation of game rules for competing contestants to fraternize like this 🤣😆🙈

Text:
Both quartz and graphite can form in the same kinds of rocks, either entangled together or with graphite as an inclusion within quartz. This gradient most often in hydrothermal fluid. As the fluids cool, carbon precipitates out first as graphite with silica crystallizing into clear quartz crystals around it.

Remember minerals: You can't both advance for breaking the rules, but you can both go home.
