Australian Black Opal 1.080ct Loose
Opal is a gemstone characterized by the shimmering play of iridescent light. There are several types of opal, but among them, the red flames flickering in the jet-black darkness of black opal are captivatingly beautiful. The body colors include black, blue, and gray. The photos were taken using a penlight.
This is a black opal from Lightning Ridge, Australia. A vivid play of color, primarily green, spreads across the deep body color, and depending on the viewing angle, you can also enjoy flashes of blue, yellow, and orange. The enchanting appearance unique to natural opal is its charm.
