A bright and showy opal with a Flagstone Harlequin pattern.

The numerous flagstones have bright and crisp fire colours that move in clean rolling flashes over each flagstone. The colours move from bright candy red to orange to yellow and bright green to shades of blue and then purple. A hint of pink purple shows through on some angles. Rotating the opal in the low light still shows the bright colours rolling over the flagstones.
