The Assay Office
The Welcome Stranger went to the bank in three pieces, split on a Dunolly anvil.
At Dunolly, in February 1869, no scale at the bank could take the Welcome Stranger nugget. The blacksmith Archibald Walls split it on his anvil into three pieces, which then went across the counter of the London Chartered Bank of Australia; in the end the finders were paid about £9,381. Triptych lines up three square windows of nugget relief on a wide band, separated by polished bars: three parts of the same block, side by side.

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 Assay Office nugget collection: rings in solid 14K gold or sterling silver shaped like the bars, ingots, octagons and stepped frames of the assay trade, the nugget relief set inside them; most are nugget signet rings. At the assay office, loose gold was melted, tested for fineness and cast into stamped bars.
