What Is Australian Crystal Opal?
Australian crystal opal is a type of precious solid opal that is completely clear or semi transparent. Unlike other varieties, it does not have a dark ironstone or potch backing. Because light travels directly through the silica structure, the internal colors appear to float brightly inside the clear gemstone.
Where Is Our Crystal Opal Mined?
Our collection primarily features crystal opal mined in Lightning Ridge, New South Wales. While this town is universally famous for black opal, it also produces exceptional quality crystal opal. We also occasionally offer beautiful pieces sourced from Coober Pedy in South Australia. The Gemological Institute of America confirms that Australia is the leading global source for these natural solid opals.
The Beauty of Black Crystal Opal
Because we focus heavily on Lightning Ridge, many of our stones are classified as black crystal opals. These gems have the same clear transparency as standard crystal opal but feature a slightly darker body tone. This darker base creates a stunning visual contrast, making the internal flashes of color stand out even more brilliantly.
How to Choose a Crystal Opal
When choosing your gemstone, pay attention to the level of transparency and the brightness of the internal colors. Stones that are perfectly clear with strong red and orange fire usually have a higher value. Since they are transparent, these opals look incredible in open jewelry settings that let light enter from the sides and the back. We encourage buyers to read our guide on how to set crystal opals to understand optimal backing methods.
Care and Viewing Advice
Solid opals have a hardness of five to six point five on the Mohs scale, meaning they need gentle care. Clean your stone using warm water and a soft cloth. Do not use harsh chemical cleaners. To see the brightest colors, view your opal under natural sunlight.
