This is a shaped and polished, ready to mount or display, natural Lightning Ridge opal from the mines of Australia.

It is round, polished on one side and is 12mm in diameter, 3mm thick and of 4.35 carats.

This stone is a grey opal layer on a black backing stone, with pin-fire flashes of red, blue and green across its entire surface.

A totally unique stone, which would make an unusual ring/pendant or simply kept as a mineral sample.
