Creedite is named for the place of its initial discovery

The spectacular display of colors these specimens display can be formed by two different geological processes: the oxidation of pyrite causing ultra-thin layers of iron oxide to form on the surface

Fluorite crystals are well shaped

The “Benz” part of the name comes from the tip of some calcite crystals which have a clearly defined three-pointed star of pyrite

resulting from the oxidation of its copper and sulfide components

Chalcedony Tanzanite Creedite is named for theA silicone based mineral closely related to quartz and agate, Chalcedony has a unique crystalline structure that gives it an enormously variable appearance. This mineral forms in a similar fashion to agates and geodes but due to heat and pressure at the time of formation results in a distinct look and almost silky texture. Chalcedony can be found in a range of colors but most often occurs in semitransparent or white. It has a long archaeological
