No. 507 · The River
Rounded plates over a wide, low band. A riverbed nugget ring in solid 14K gold or sterling silver.
The River
The heaviest gold sinks to the bottom, among the stones of the riverbed.
The heaviest gold does not stay on the banks; it sinks to the bottom, among the stones of the bed. In the 1850s, miners in the Sierra Nevada dammed and diverted rivers to work the dry bed. A dry bed can still give up gold: in 1995, near Kalgoorlie in Western Australia, a prospector whose name was never published found a nugget of about 56 pounds in a dry creek bed. That nugget, the Normandy, is now on show at the Perth Mint. Riverbed carries large, rounded plates, like stones smoothed by the current.

Your order details identify the selected metal. Weights are estimated from the 3D file we cast from. How the estimate works · The rounded comfort-fit interior is part of the 3D design we cast from.

The River nugget collection: rings in solid 14K gold or sterling silver, most of them bands, textured all the way round like gold-bearing gravel lining a riverbed. Placer gold is gold the river has already freed from the rock and dropped in its gravel.
More from The RiverOur 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.
