First the basalt, erupted as South America pulled away from Africa, trapping gas bubbles as it set. Then the green celadonite, forming as the rock weathered and lining the empty cavity. Then silica-carrying water working in through the rock, laying down quartz on that lining, picking up iron as it went. Then a very long wait while natural radiation in the surrounding basalt turned that iron purple.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eFour separate events, running across more than a hundred million years, and the result is a single surface you can take in at a glance.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eKeep it out of direct sunlight.
