Chrysocolla is a hydrated copper silicate known for its vibrant blue-green hues, often forming in association with secondary copper minerals like malachite. Fine specimens of chrysocolla are a rarity in world-class mineral collections, not due to its overall scarcity (though it is not overwhelmingly prolific) but because chrysocolla does not typically exhibit an attractive and collectible form. Although loved for its propensity for cerulean to turquoise blue color, few specimens ever approach anything close to “attractive” by the parameters of discerning mineral collectors. In fact, “colorful but amorphous” is typically the best that one could say of most chrysocolla, leaving most finds to be relegated to lapidary work.
This striking specimen features chrysocolla and malachite in a remarkable display of color, texture, and form. Measuring an impressive 28 cm across, it has rich, cerulean blue chrysocolla that has formed in sculptural botryoidal aggregates that rise and fall like an alien landscape. Tiny aggregates top the piece, adding another element of texture. Green malachite can be seen peeking through along its edges, adding visual contrast. With its unusual silhouette, rich color saturation, and size, it is a striking example of the species.
