Chalcedony is a cryptocrystalline form of silica, composed of very fine intergrowths of the minerals quartz and moganite. Chalcedony has a waxy luster, and may be semitransparent or translucent. It can assume a wide range of colors, but those most commonly seen are white to gray, grayish-blue or a shade of brown ranging from pale to nearly black.
Okenite is a silicate mineral that is usually associated with zeolites. It most commonly is found as small white “cotton ball” formations within basalt geodes. These formations are clusters of straight, radiating, fibrous crystals that are both bendable and fragile. Because of this common shape, Okenite is often called a “warm and fuzzy” stone because it brings feelings of the “warm fuzzies”, feelings of comfort and belonging. It was first discribed in 1828 for an occurrence at Disko Island, Greenland and named for German naturalist Lorenz Oken.
