Fire Opal
The Ember-Hearted Spark of Passion
Also known as: Mexican Fire Opal, Hummingbird Stone
About the stone
Fire opal is a transparent to translucent variety of opal known for its warm yellow, orange, or red body color, which gives it its fiery name; some specimens also display rainbow-like play-of-color. Indigenous peoples of Mexico, including the Aztecs, discovered and valued it before European arrival, while modern commercial mining expanded in Querétaro around 1835; the indigenous ancients were using it as early as the 850-900 CE. Mexico remains its classic source, particularly Querétaro and Jalisco, with additional deposits in Brazil, Ethiopia, Australia, and the United States. Mexican material is also called Mexican fire opal or Mexican opal, while historical accounts describe poetic names such as “hummingbird stone” and “stone of the bird of paradise.” Lore connects it with an inner flame, protection, creativity, and passion

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 Fire Opal vary, and its effects are personal rather than guaranteed. Wear or hold it with intention, let its warmth remind you of your own spark, and use it as one small flame among many.
