The story

The Assay Office

From the 1850s, San Francisco jewelers set polished gold-veined quartz in gold.

In San Francisco, from the 1850s, jewelers cut and polished slabs of white quartz veined with native gold and set them in gold: brooches, watch chains, jewel boxes. The polished stone was in the middle and the metal around it. Inverse does the opposite of our signets: a raised, flat square of polished gold in the center of the face, inside a border of nugget relief, rough gold framing the smooth.

Description
  • A raised flat polished square sits in the centre of the face, inside a border of nugget relief. Plain polished shoulders lead into the band.
  • Part of The Assay Office: set inside a bar, an ingot or a stepped frame. See the collection
Details
  • Made to order in your size, US 4 to 15, half sizes included
  • Cast by my uncle’s workshop after you order, in about 2 to 3 weeks
  • Certificate with the metal and the cast weight: how to tell if a nugget ring is real

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.

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.
