This beautiful round little Opal is a solid Australian black Opal from Lightning Ridge. On some angles, it's a dull lighter blue, on another angle it's an electric teal colour, and on another angle it has flashes of blue and green. It is so cool under every light, even when it's the plain dull blue, it's still such a nice blue! Handmade into a 9ct Rose Gold bezel set necklace. The chain is also solid 9ct Rose Gold (so no yucky colour change after a few wears!) and is the necklace is approx. 44cm total length.
