A large matrix hosts several vugs and seams of rich blue Cyanotrichite crystals. The Cyanos are mixed with sparkling Quartz crystals, so the specimen has a bright luster as well. Best appreciated with magnification, the specimen is a nice example of the specie.

Rich, bright vivid blue Cyanotrichite covers the display surface of the specimen. An older piece, ex John Marshall collection, and before that from the remarkable collection of Gunnar Bjarby and also David Garske. Five old labels are included. While the druse of Cyanotrichite is composed of very tiny crystals and spherical clusters, the dense coverage is impressive by naked eye. The back side of this piece also has a fair sized area of Cyanotrichite and old labels, collection numbers etc. A rich piece for a lesser known but still classic US locale.
