This is a shaped and polished opal, ready to mount or display. It is a natural Coober Pedy opal from the mines of Australia.
It is a tear-drop shape, slightly domed at the edges and polished on the front. It measures 2.3cm x 1cm at its widest point, and weighs 2.9 carat.
The background of this stone is cream-coloured, and it displays pin-fire flashes of mainly pink, red and green across its entire surface.
A beautiful opal specimen, which would make a stunning pendant or could simply be kept as a mineral sample.
