Description

Excellent cyanotrichite specimen lining a cavity, composed of abundant fibrous tufts and radiating sprays displaying an exceptionally vivid azure to electric-blue color.

The cyanotrichite occurs as extremely fine, elongated fibers, commonly forming cottony spherical aggregates and radiating needle-like sprays, giving the specimen a distinctive silky and airy appearance. Some longer isolated needles clearly protrude from the aggregates, enhancing the sense of movement and depth.

The cavity is bordered by a beige to light ochre matrix, likely carbonate-rich, which frames the crystallized area and creates a strong visual contrast with the saturated blue of the cyanotrichite. The dense and evenly distributed growth results in a highly balanced and aesthetic composition.
