【Sale starts at 10 PM on July 20th】Australian Black Opal 0.894ct Loose Stone

Opal is a gemstone characterized by the iridescent play-of-color. There are several types of opals, but among them, the red flame that flickers in the jet-black darkness of a black opal is mesmerizingly beautiful. The body color can be black, blue, or gray. The photo was taken using a penlight.
