This Opal is super cool. In some lights it's a dull, dark blue almost no play in the colour, but you tilt it, even just slightly, and the most amazing vibrant green flash passes through the whole Opal. Turn it to another angle and you'll see a deep purple flash, and then another, a bright blue flash. In some lights, you'll even see the black vein inclusions within the Opal. It's such a unique and interesting Opal that you will not be able to stop looking at! Handmade into a 9ct Yellow Gold bezel set ring.
