The story of Ingot

The Assay Office

An ingot is metal as it comes from the mold. A long rectangular tablet sits across the finger, its nugget relief set in a stepped polished frame.

An ingot is made to be handled, stored or melted again, never to stay as it is. Some of the best-known ingots of the California rush are those of Kellogg & Humbert, assayers in San Francisco, raised from the wreck of the SS Central America; the largest of them, the Eureka bar, is stamped 933.94 troy ounces, about 64 pounds. Ingot sets a long bar across the finger, framed like an ingot in its mold, with the nugget relief where the raw metal would be.

Description
  • A long rectangular tablet sits across the top of the ring, with nugget relief set into a stepped polished frame. Its sides are flat and polished, above a plain band.
  • Part of The Assay Office: set inside a bar, an ingot or a stepped frame. See the collection

The Assay Office

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.

Our workshop makes engagement rings. It casts each nugget ring in your size after you order, from the 3D file I draw, and the certificate gives the metal and the estimated weight.

Our story

14K or silver

Solid 14K gold keeps the warm yellow of our pictures. Sterling silver is the same ring again. Each has one fixed price per design.
