Blue Chalcedony

Q: What is Blue Chalcedony made of?

Blue Chalcedony has the chemical formula SiO₂, crystallises in the trigonal (microcrystalline) system and measures 6.5 – 7 (Mohs) on the Mohs scale. Blue chalcedony is a cryptocrystalline variety of quartz whose soft blue colour is a Rayleigh-scattering effect from micro-inclusions rather than a chemical pigment: fine particles scatter shorter wavelengths of light much as the sky does. Classic Namibian material from the Karas region shows the most saturated colour; the Eskişehir deposits of Anatolia and the Mtorolite plateaus of Malawi supply much of the current market.

I. The Metaphysical Reading

How the stone has been held.

Blue chalcedony is one of the classical throat stones for measured speech, carried before difficult meetings and long-form teaching. Practitioners associate its waxy translucence with words that carry warmth even when the message is firm.
