Blue Opal
The Clear Voice of the Throat
About the stone
Blue opal is hydrated silica with a soft blue to blue-green color, usually classified as common opal because it lacks the rainbow flashes of precious opal. Although opal has been valued since antiquity, blue opal has no single documented discoverer; commercially important deposits near Acarí in southern Peru were identified in the early 1970s. Peru is a celebrated source, with blue opal also found in Oregon, Idaho, and Nevada in the United States, as well as Indonesia and Slovakia. In modern crystal lore, it symbolizes tranquility, emotional healing, and open communication.

- It is traditionally thought to be beneficial to the throat, mouth and sinuses, and people who talk a great deal sometimes keep it near as a reminder to care for the voice.
Care and handling
Opal contains water, so it is best protected from sudden temperature changes, strong heat and very dry air, which can cause crazing or cracking. Clean it with a soft damp cloth and mild soap, dry it gently, and avoid ultrasonic cleaners, steam and harsh chemicals. Keep it out of long periods of direct sunlight, and store it wrapped softly apart from harder stones, because at 5 to 6 on the Mohs scale it scratches more easily than quartz.
Individual experiences with Blue Opal vary, and its effects are a matter of personal belief. Hold it with an open mind, speak your own truth kindly, and let the stone be a quiet reminder rather than a promise.
