Mineral Specimen #6896 Silver, Copper
Caledonia Mine, Ontonagon Co., Michigan
3.5 x 3.2 x 1.8 cm
1.4 x 1.3 x 0.7 in
The majority of this specimen is composed of native Silver. The Silver has a rough texture and exhibits some crystallization. There is also a small amount of native Copper present. The green color is a combination of Copper alterations and likely Epidote.
Condition: Very Good
Flaws: There is no appreciable damage to the specimen. However, it should be mentioned, it is highly likely the specimen has been dipped in a matte, clear, non-yellowing lacquer to prevent tarnishing. This was a common practice employed by the past owner and likely has also intensified the green colors.
