What is Cavansite?
Cavansite is included in the GEMHOOD mineral and gemstone encyclopedia as an educational guide to its visual characteristics, durability and care. Cavansite is prized by mineral collectors for intense blue crystal sprays, particularly spherical clusters on pale matrix. Its delicate crystals are easily damaged and are more suitable for protected displays than rings or everyday jewellery. Typical observed colours include vivid blue to blue-green. Mohs hardness is approximately 3–4; this measures resistance to scratching, not toughness, cleavage or chemical stability. Recorded mineral localities include India, United States; these are examples of occurrence, not proof of where a particular stone originated. Look for intact radiating crystals and clear disclosure of repairs, gluing or other stabilisation. Avoid water soaking, ultrasonic equipment and scrubbing; use a soft dry brush only on robust areas.
