About opal colours photographs: The colours of an opal shown in photographs vary in different lighting and
the angle of the shots. To best show the colours of the opals I sell, I take photos from different angles and
different lighting conditions to give you the truest possible images of my opals.
Please see above video of this opal. It was taken in a photo studio under LED lights.

Black Opal: Black Opal is found mainly at Lightning Ridge N.S.W. 600km northwest of Sydney.
First noticed in the late 1800’s, it wasn’t until 1905 that the first shafts were dug and a layer of black “potch”
(non-precious opal) was discovered. Within this layer of potch is found precious opal called Black Opal a name
they have because of their dark body colour that ranges from light grey to dark black. Their rarity makes them
the most valuable of all opals.

Body Tone: Opal body tone is classified using a chart created by the Opal Association here in Australia.
An opal’s body tone is determined when the stone is viewed face-up and range from the darkest “N1” to the lightest “N9”.
