This truly is an amazing AAAA Welo Opal with incredible flashes of all the colours expected in a high quality Opal and I have tried to capture this in the photographs.  I have not used any filters or enhancing light on the photos (just removed the background colour).
 
The Oval Opal measures 14 x 10 mm and is set in a four claw design in Platinum.  It is set on an 18 inch Spiga Platinum Chain and will be presented in a high quality black soft touch pendant box.
 
 
All measurements are approximate.
