This is a really large, hackly mass of gold encrusting a central core of light-mass limonitic matrix, from the classic Aussie goldfields. It has a lot of size and drama for a nugget from here, not the usual boring pancake style. The large amount of matrix enmeshed by the gold is a nice touch, and somewhat unusual. This matrix doe snot comprise much of the mass, though, which is certainly approx. 95% gold by weight. 284 grams...SO THIS IS NEARLY BULLION PRICE at today's gold values.
