Cavansite is a striking blue mineral prized for its vivid, almost electric color, which ranges from sky blue to deep cornflower. It typically forms as small clusters of rounded, druzy crystals, and most of the material on the market comes from the trap rock quarries of Pune, India, where it is found alongside zeolite minerals like stilbite. Its rarity relative to other blue minerals and its unmistakable color make it a favorite among mineral collectors looking to fill a distinctive niche in a collection.
This collection is made up of blue cavansite crystal clusters from India, many sitting on white stilbite matrix that sets off the blue coloring by contrast. Look for pieces where the cavansite forms tight balls or sprays across the host rock, as well as clusters where the stilbite crystal structure is clearly visible underneath. Condition of the matrix, density of the cavansite growth, and the sharpness of the blue color are all worth examining closely before choosing a piece.
