1.42ct Round Royal Blue Directional Lightning Ridge Black Opal
This is an 8mm diameter almost perfectly round Lightning Ridge Black opal exhibiting an electric royal blue flash.
It is somewhat directional in it's display. This means that the colour flash can only be seen from certain angles however this can add to the interest of the opal.
Careful setting in the correct orientation will show this stone off to it's best advantage as shown in the photograph. If this opal were not directional it would be around 10 times the price it is on offer for here! An absolute bargain for a skilled opal jeweller to work with.
