Interesting patterns of the diffracted colours are rare and when combined with brilliance, have an enormous impact on the value. Small type patterns are less desiable than broad patterns such as rolling flash, straw pattern, Chinese writing, ribbon and harlequin are highly sought after.
So, this very rare "Chinese writing"opal amazed me a lot!!
How perfect it is...
