Gemstone: Australian Boulder Opal

Boulder opals grow within the cracks and voids of its host stone, ironstone. This results in a thin layer of opal which, when cracked open, presents a surface of opal atop its host. The layered beauty of Boulder Opals holds a variety of vibrant colors and iridescence.

Care: All opals are fragile like glass: be extra careful to avoid abrasive surfaces, and avoid knocking your opal against hard surfaces. Extreme temperature shifts can cause cracks. To keep your opal clean, use warm water with mild soap and a soft toothbrush or cloth. Do not use a steam cleaner or ultrasonic cleaner.
