Photos are taken with the stone lightly wetted and under bright lighting to better showcase its natural play-of-color and polishing potential. This is a preform cabochon and has not yet received its final polish. Once professionally finished, the play-of-color may appear even more vibrant. As with all natural opals, color and brightness will vary depending on lighting conditions, viewing angle, and whether the stone is viewed wet or dry.
