Cavansite is a beautiful gemstone! It's named after its chemical composition: Calcium Vanadium Silicon. It was discovered in 1967.  Cavansite is only a hardness 3-4 so is relatively soft and, if used in jewelry, should only be used in low-impact pieces such as earrings or pendants. Cavansite is transparent to sub-transparent with a vitreous luster.  Its colour may be blue-green, dark blue, or a brilliant sky blue. Cavansite is only found in a few locations in: Brazil, India, New Zealand, and in the state of Oregon.
