A natural Ethiopian opal rough displaying vibrant flashes. The specimen offers an attractive combination of precious opal and matrix, with several areas exhibiting vivid play-of-colour from different viewing angles. Its natural, uncut state makes it suitable for collectors, lapidary enthusiasts or display, while preserving the geological character of the original material. Opal colours arise from their interaction with light and vary depending on viewing angle. Images aim to show the play-of-colour across different angles.
