The story

The Assay Office

Bullion is gold in bars. This one keeps a bar’s flat polished sides and puts the nugget relief on top, where an assayer stamped the weight and fineness.

In 1850s San Francisco, placer gold went to the assayer, who melted it and cast it into bars. Each bar was stamped with the assayer’s name, a number, the weight, the fineness in thousandths and the value: bars from the firm of Kellogg & Humbert, raised from the wreck of the SS Central America, still carry those figures. Almost all the big nuggets of the time ended up melted; the Welcome Nugget from Ballarat went into sovereigns in November 1859. Bullion keeps the shape of the bar, straight smooth sides, and leaves the nugget relief on top.

Description
  • A square block head with nugget relief on top and flat polished sides, which meet it along an uneven edge. Wide plain shoulders run into a sturdy band.
  • Part of The Assay Office: set inside a bar, an ingot or a stepped frame. See the collection
Details

Occasion

Your order details identify the selected metal. The weight is estimated from the 3D file we cast from. A cast ring comes out 2 to 3% lighter than its file, and the range shown already includes this. Your price is fixed when you pay and is never adjusted to the weight; your certificate records the actual weight. The interior is measured on the 3D design; finished samples still need workshop verification.

About the collection, the workshop and the gold

No. 531 Octagon nugget ring in 14K yellow gold, on a ledge of dark slate

The Assay Office

At the assay office, loose gold was melted, tested for fineness and cast into stamped bars. These rings take the shapes of that trade: bars, ingots, octagons and stepped frames, with the nugget relief set inside them.

My uncle’s workshop

My uncle runs a jewelry workshop and makes engagement rings for brides. I develop the designs; each one is a 3D file, measured for its weight in every metal and size. His workshop casts the ring in your size after you order, and the certificate gives the metal and the cast weight.

Our story

14K, vermeil or silver

14K keeps the warm yellow of our pictures, and its price follows the gold price. Vermeil is the same ring in sterling silver covered with 18K gold, and sterling silver is the same ring again. Sterling silver and vermeil have a fixed price per design.
