The colour play features a sparkling deep green and blue on a black background. It presents with a pinfire pattern when stationary or rotated. This stone is rated by me as N2 in body tone - using the Opal Association Base Body Tone Guide as reference - and brightness of around B3.Shaped in a round form, it has been finished with a low cabochon top and flat bottom. It weighs 0.52cts and measures 12mm x 5mm x 1mm. The attached photos form an integral part of the description. Apart from cropping they have not been enhanced in any way. The material I present for sale (rough or finished) has been either mined or prepared by me and therefore I try to keep prices as realistic as possible. NOTE: There are many good sites on the internet that offer valuable information about precious opal and its unique qualities. Thank you for your interest. Please contact me if you have any questions.
