No. 508 · The River
Fine grains all the way round a wide band. A placer nugget ring in solid 14K gold or sterling silver.
The River
A placer is sand or gravel that holds loose gold. Small, dense grains cover a 10 mm band all the way round, between two narrow polished edges.
On January 24, 1848, checking the tailrace of a sawmill on the South Fork of the American River, James Marshall saw bright flakes in the water. He bent them with a fingernail and struck them with a stone. They passed both tests: it was gold, placer gold, freed from the rock by the river. The USGS says up to 90 percent of the gold in a river placer lies in the lowest 3 feet of gravel and the top of the bedrock, mostly as flattened flakes. Placer carries that texture: dense grains all the way round, between two smooth edges like two riverbanks.

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.
