The story of Boulder

The River

A boulder is any rock fragment over 256 mm. Here it is one broad dome of large nugget plates and deep fissures, on smooth polished shoulders.

In a placer, the gravel runs from fine sand to rocks too heavy to lift; on the geologists’ scale, a boulder starts at 256 mm. The USGS explains that gold, being very dense, settles where the water slows down: on the inside of bends, in the pools below rapids and just downstream of large boulders. Boulder is one full round dome of large nugget plates and deep fissures, like the rock the gold stops behind.

Description
  • A broad rounded dome is covered in large nugget plates and deep fissures. Smooth polished shoulders taper into a plain band.
  • Part of The River: textured all the way round the band. See the collection

The River

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.
