Chalcedony is quartz with the volume turned down — a cryptocrystalline form of SiO₂ whose crystals are far too small to see, which is exactly what gives it that soft, waxy, lit-from-within glow. The blue variety is the one most people mean by the plain word “chalcedony,” a milky powder-blue that reads like fog over water. Humans have carved it since deep antiquity — the Greeks made cameos from it — and the name itself most likely comes from the ancient town of Chalcedon on the Bosphorus.
