A stunning early 20th century unmarked gold cabochon fire opal and white sapphire pendant. I love this piece, the central opal is so fiery, it is open to the back which allows the light to shine through creating a kaleidoscope effect. The photos do not do this piece justice. There is slight wear/dents to the gold on the back of the pendant, see pictures.
It measures 17.1mm high (including bail) by 2.5cm wide.
