Australian Black Opal 0.421ct Loose Stone
Opal is a gemstone characterized by the flickering of iridescent light. There are several types of opal, but among them, the red flames dancing within the jet-black darkness of the black opal possess a beauty that is impossible to look away from. The body tone can be black, blue, gray, and others. The photography was performed using a penlight.
