Green Flash Two Tone Dark Opal from Lightning Ridge.
Dark opals sit between black and white tone and sit on the body tone scale of N5 to N6. It is opaque like a black opal but it has a slightly lighter body shade. Dark opals can be found in every opal mining area in Australia and would be considered one of the most common type of precious opal but not the least expensive.
The play of colour, brightness and pattern of a dark opal is what gives it its value.
Measurements:
13.9mm long x 11.2mm wide
4.2 Carats
Grading:
N4 & N5 Dark Tone - this Opal displays both N5 & N6 body tone
B3 - Bright Nice Play in both artificial light, sun and shade
