what is yowah nut
‘Yowah Nuts’ are a sub species of Boulder Opal, they are typically small boulders about the size
of a walnut and are found in a unique formation consisting of a regular band containing nuts packed
in a conglomerate. The opal is found either as a central kernel, or as thin veins, surrounding an
ironstone centre or traversing the nut, without reaching the outer edge.
in a conglomerate. The opal is found either as a central kernel, or as thin veins, surrounding an
ironstone centre or traversing the nut, without reaching the outer edge.
* Although predominantly found in the vicinity of Yowah in an area of only 1.5 square
kilometres, nuts with gem opal kernels have been found at the Koroit Opal fields.
Formations of a similar type are found in lesser concentrations on the northern opal
fields where the miners generally refer to them as matrix opal.
It is safe to say that out of every hundred nuts cracked
only a few are considered gems.
* Every yowah nut is unique and those that contain precious opal make magnificent
specimens and gems, while the ‘duds’ are fascinating for mineral collectors.
Often the nuts are sliced as a conglomerate, revealing a number of different sized
nuts and various patterns of opalisation within a matrix - the results are marvellous
works of art!
* Boulder Opal Matrix is a generic term which can be used to describe the banded growth or leafed inclusion of precious opal with and/or in the ironstone host rock. The wondrous mixture of ironstone and flecks or veins of colourful opal creates endless patterns and designs, referred to as ‘picture stones’ or ‘fun stones’, these are eminently collectable.
