Ex. A. E. Seaman Musuem

A small salmon pink/red colored Datolite nodule that has been cut and polished. The color is translucent when back lit. The color is due to micro inclusions of native Copper. Small red dots can be seen in the photos. These are not easy to see in person except with some magnification. They are visible in the photos because the photos are a few times larger than real life. A thick white colored rind surrounds the inner core of color. This is common in Datolites from the Copper Harbor area. The polish is very good but there are two small areas which slightly show saw marks. The last picture is one which I took several years ago of the smokestack from the old smelter which was located at the site. This has been abandonded for over 100 years and is in remarkably good condition. The dwarfed black spruce at the top subseqeuntly died a couple of winters ago.

Condition: Excellent

Flaws: Nothing Appreciable
