An euhedral crystal of 0.7 mm only, and a neat cluster behind.

A pristine twinned antlerite crystal of less than 0.2mm (material analysed by single-crystal XRD). I suspect the silky red balls at the base are ultrafine hematite concretions.

Chalcedony

Detail view of a 30vmm cavity in rhyolite with probable spherical siderite coated with micro spherical chalcedony and secondary calcite overgrowth, self collected. Typical "boxworks" developed by the weathering of massive sulfide ore deposits in the oxidation and leaching zone. Most of the ore elements have been leached and redeposited further down in the deposit leaving a mixture of iron oxides/hydroxides and silica minerals.
