Opal
Certificate
This
mass weighs, as is, 8,835 kilograms and is compact, irregular
shape and blocky, with diameters of its dies up to 280
millimetres in length. The exterior surface is coated with
clay, part of which is broken through by broken opal surfaces
which have a brilliant precious opal fire-play, expressed in
brilliant green and orange irisations which was the favoured
colour combination for the precious opals at the turn of this
century. The opal shows the pattern of the floral harlequin
order and is of remarkable continuity as seen from its
exposure over the surface by the occluded sections.
