Key Fact
Description
This is a specimen of raw opal, also known as rough opal, showing a striking play of color. The opal matrix is embedded within a host rock, displaying flashes of vibrant green and hints of blue and red against a translucent white base. Its unpolished, natural state highlights the inherent beauty and potential of the gem. The rough texture and earthy tones of the host rock provide a stark contrast to the luminous fire within the opal.
History
Opals have been treasured for millennia, with ancient Romans believing they contained the tears of gods or the solidified laughter of joy. Historically mined from various locations worldwide, their unique play of color has captivated cultures and inspired art. This particular rough specimen, while its exact origin is unknown, represents the raw, untamed beauty of opal formation, a testament to the geological processes that create these fascinating gemstones.
Facts
The mesmerizing play of color in opals is caused by the diffraction of light through microscopic spheres of silica. The term 'potch' refers to the common opal that lacks this precious play of color or has very little of it, often remaining embedded in its host rock. The spectral colors seen here, particularly the green and blue, indicate a valuable flash, making this piece intriguing for lapidaries and collectors.
Value Fact
Rough opal prices vary dramatically based on color, pattern, clarity, and the amount of precious opal present. Specimens like this, with visible fire within the rough matrix, command interest from gemstone cutters and collectors. The market for unmounted opals is driven by their potential to be transformed into stunning jewelry, with exceptional pieces fetching significant prices depending on the quality of the final cut and polish.
