Kyanite, whose name derives from the Greek word kuanos sometimes referred to as "kyanos", meaning deep blue, is a typically blue silicate mineral, commonly found in aluminium-rich metamorphic pegmatites and/or sedimentary rock.
Kyanite derives its color from the trace elements or minerals iron and titanium, similar to the ones that give the blue sapphire its color.
Kyanite, like most gemstones, is available in all qualities: VVS, VS, SI1 and I, though VVS quality Kyanites are hard to find. The common faint natural inclusions visible to the naked eye are minute needle-like inclusions, feathers and color zoning.However as the stone is dark the inclusions arent that obivious
At present here are no treatments known that could enhance kyanite.
Kyanite's elongated, columnar crystals are usually a good first indication of the mineral, as well as its color (when the specimen is blue).
