Chalcedony – Blue Tumbled Stones

Blue Chalcedony has a trigonal crystal system and is in the mineral class of oxides in the quartz group. Its coloring is generally light blue to white, sometimes yellow and it can be partly banded. It is known as a pure, fibrous quartz that is formed at temperatures below 100 degrees celcius from solutions that are rich in silicic acid. It is usually a primary formation and rarely occurs from a secondary origin.

Blue Chalcedony gains its light blue coloring from what is called the ‘Tyndall effect’. As light is bent through its microscopically fine crystals, the red portion of light is absorbed and what our eyes see is the reflected blue portion of light. Chalcedony is part of many stones used in healing and they each carry its benefits as well as their own. Some familiar to many would be Blue Lace Agate, Bloodstone, Carnelian, Jaspers, Onyx and Petrified Wood.
