What is an Andamooka Matrix Opal you may ask?

From the GIA website:

Matrix Opal from Andamooka South Australia is a precious opal-included porous rock that is commonly colour enhanced) carbon impregnated) to initiate the highly prized black Opal from Lightning Ridge. Often referred to as ‘sugar treated’ as a basic sugar acid-carbonising technique is used to darken the cream coloured matrix pr pre-polished Opals so that the play of colour is more prominent.


So basically an Andamooka matrix Opal is a solid Opal with a light(er) colour which has been enhanced to give the stunning colour we see in this example.

A stunning blue/brown/purple body tone with flashes of intense reds, blues, oranges, greens and golds shimmer over the entire large 2cm x 1.4cm Opal.

Bezel set to a solid gallery to simple wide 9mm shoulders which taper effortlessly to a thick flat shank.

Not too high on the finger at a rise of 6mm, with an impressive finger spread of over 2cm x 1.5cm, this vibrant and stunningly attractive ring is one of our favourites and we are sure it’ll be yours too!
