Colossal Single Quartz Crystal. 11¼ in. high by about 4½ in. wide at widest point. Cut smooth on bottom so that it stands perfectly vertical as a sensational display piece. Weights 12½ pounds. Exterior clarity of this specimen is such that its inner composition can be seen as in a prism, showing how it was formed many millions of years ago. Of particular interest are the inclusions, which include traces of pinkish-red copper and a fern sprig. The presence of ferns in quartz specimens is of extreme rarity, far more so than insects in amber. From Brazil.
Estimated Value $300 - 400.
