Buy Opal Shells


Opalized shells have become highly sought after by collectors globally, including mineral enthusiasts who have recently taken an interest in these unique specimens. The trend has been highlighted on the Discovery Channel's "Opal Hunters," where new miners explore the Shell Patch opal field in Coober Pedy, renowned for its top-quality opalized shells and belemnites. The series showcases their innovative mining methods, from excavating old mines to using dynamite and UV-equipped excavators for nighttime searches to uncover overlooked opals.


Buyers particularly prize complete, unaltered opalized shells, preferring natural specimens that retain their original appearance. Coober Pedy, once submerged under the sea, holds vast deposits of these sea water shells, although many lack distinct coloration. In contrast, shells from Lightning Ridge, sourced from freshwater creeks, are less common and prized for their rarity in containing colored opals, especially valuable if they are black opal shells.


Broken shell pieces are often available at favorable prices and are popular for crafting unique pendants or using as inlay material. Larger specimens from Coober Pedy exhibit a diverse range of ancient sea creatures preserved in natural matrix from the Cretaceous period, including clam shells, mussels, gastropods, fish vertebrae, and belemnites. These shells sometimes feature gypsum formations that enhance their opal colors.


Collectors of opalized shells are discerning, always seeking specimens with vibrant fire colors. Cleaning these fossils, embedded in hard potch, requires careful handling to prevent damage, while those in softer potch can be cleaned more easily without risk. Professional mineral cleaners play a crucial role in preserving and presenting these fossilized treasures for collectors.
