Collection

The Assay Office nugget collection

The Assay Office nugget collection: rings in solid 14K gold or sterling silver shaped like the bars, ingots, octagons and stepped frames of the assay trade, the nugget relief set inside them; most are nugget signet rings. At the assay office, loose gold was melted, tested for fineness and cast into stamped bars.

The rings

At the assay office, gold was melted and cast into bars stamped with the weight and the fineness. These rings keep the hard edges of that trade: Bullion the straight smooth sides of a bar, Octagon the eight sides of the 1851 fifty-dollar slug, Deco frames that step down level by level to the nugget.
