Chunks of peacock blues and feather greens and teals leap out from this fine, Australian black opal.

No matter the angle, this gemstone delivers color and exciting flashes.

A round, flat cabochon, it measures 16 mm in diameter. Three major fields or swatches of eye-popping hues dance across the surface.

Just for visualization of its scale, this is larger than a 13 carat diamond! Yet its deep, resonant, and underwater seascape shades render this wearable for almost any occasion, dressed up or down.

It is set in a coronet mounting of 18k yellow gold with a base of open pyramids.

An old mine-cut diamond tops the opal and at the tip, a shapely bale holds three petite rose-cut diamonds.

One of the prettiest and showiest black opals we have had the pleasure to offer. If you adore blues and greens, this is unmissable.

This stone is also desirably for its showy diameter. Displaying all its glory on the top rather than in often unseen depth. Remember too that opals are lightweight gemstones!
