The story

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, weighs about 80 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

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.
