This specimen is almost entirely eucryptite by weight, although one side is covered by a layer of feldspar and a scattering of mica crystals. Under short-wave ultraviolet, the eucryptite glows a deep and bright red, which does not image well with my camera. The eucrytite is outlined by a thin layer of willemite, which glows an intense green, which ALSO does not show up on this camera. There is no "blue" florescence - the camera has captured the blue reflection of the UV lamp. This is a great specimen for a short-wave UV cabinet.
