Ontario’s Cobalt District, one of the world’s premier silver mining camps, produced tens of millions of ounces of silver over a one hundred plus year history of mining and exploration. This is an excellent example of classic twinned “herringbone” silver crystals which have been expertly etched from their enclosing calcite matrix. The size and perfection of of the ‘herringbone’ crystal aggregates is notable for Cobalt, and they repose aesthetically on a a piece of typical diabase matrix, sawn on the base for display. The silver crystals have a thin coating of ‘fuzzy’ of safflorite and other Ni-Co arsenides, typical for the area. A Canadian mineral classic! Annette Slade photo.
