Natural Crystal Opal Cabochon
This is a natural loose crystal opal cabochon, presented in a white square gem jar with a black foam insert. The opal features an irregular, freeform semi-oval shape with a smooth, polished domed surface. It exhibits a vibrant play-of-color characterized by strong flashes of orange, red, green, and yellow across a translucent light-gray to white body tone. The most prominent pattern appears to be a broad flash or floral play-of-color. The stone's transparency indicates it is likely a crystal opal of Australian origin, though laboratory testing would be needed to confirm 'Coober Pedy' or 'Lightning Ridge' provenance. The surface appears to be in good condition with a high-luster polish, free from visible surface-reaching cracks or crazing, which is a common stability issue in opals. The surrounding context of silver jewelry and mosaics suggests a contemporary vintage age, likely 20th century. The quality is indicated by the high saturation of the warmer color spectrum (red and orange), which typically commands a higher value in the opal market than green or blue dominance.
