A fantastic and historic slabbed specimen of Gold (var "Electrum") from the famous Idarado mine (650 Level, Tomboy Vein). The Gold has a lustrous, bright, metallic appearance, and stands out beautifully against the snow-white Quartz and black Sphalerite matrix. It was collected by Andy Sutyak of Ouray, Colorado in 1927. The piece later went to Clancy Fleetwood (Brian Kosnar's great-grandfather), and in 1984 became part of the famous Colorado mineral collection of Richard Kosnar, whose hand-painted catalogue number (G1084Tb) is on the bottom of the specimen. Ex. Richard Kosnar Collection.
