Adamite is a rare mineral at the Sterling Mine. This specimen isn’t very pretty, but it has good coverage for the locality. Note: The label says “cuproadamite”, but according to Dunn’s Franklin and Sterling Hill monograph (p.653), it is adamite or “cuproan adamite”. The specimen is Ex “Jones” via the Franklin Mineral Museum and comes with that label.

The first pair of photos (FOV 6.6 x 4.5 mm) shows some of the larger (to 2.2 mm) spherules of adamite. These are all broken. According the Sterling Mine adamite comes in many colors, among them light and dark brown, green, yellow-green, bright pink and deep yellow. This stuff is mostly green. The pale blue stuff is aurichalcite (per the label – I’m no expert on Cu minerals).

The second pair of photos (FOV 6.8 x 4.4 mm) shows more of the aurichalcite on a crust of adamite.

The third pair of photos (FOV 6.4 x 3.9 mm) shows some unbroken spherules of adamite, but they are only ca 0.5 mm in diameter.
Single item shipping weight (no case) is 3.2 oz (94 g). For shipments outside the USA, up to a total weight < 8 oz (225g), this can be combined with items from this or other auctions for the same postage.

Within the USA, postage increases by about $0.20 per ounce. Above 13 oz, I will use Priority Mail ($9.25 including packing).
