“What could be heavier and more impenetrable than a rock, the densest of all forms? And yet some rocks undergo a change in their molecular structure, turn into crystals, and so become transparent to the light. Some carbons, under inconceivable heat and pressure, turn into diamonds, and some heavy minerals into other precious stones.” --Eckhart Tolle, A New Earth

Topaz with lepidolite And I quote: Most topaz come from pegmatites. This large crystal capped with lepidolite is naturally blue. This is rare in nature, however, and most blue topaz is man-made by irradiating and heating colorless or yellow-brown topaz. The chemical composition of topaz is Al2 SiO4(F,OH)2.
