Much bluer than most Okorusu mine Fluorite, this small cabinet-sized display specimen is very eye-catching, especially with good directional lighting. Primarily an aggregate of intergrown and twinned cubic crystals, it is their prominent and very attractive colour zoning which grabs ones attention. Surrounding a thin core of matrix the Fluorite cubes form a ridge-like aggregate with a rich underlying teal blue-green colour but with an electric blue line floating within the outer edge of the crystals marking the cubic form. Reaching up to 2.1 cm on edge the Fluorite crystals are a good size and show a transition from slightly frosted surfaces (crystal faces) on one side upwards (depending on how the specimen is displayed) to more glassy translucent to transparent crystals. There is slight chipping to a few corners and edges of the Fluorite crystals but this does not overly detract from its amazing colour and internal zonation, which is worldclass. With strong back lighting the zonation really comes alive, with pale lime-green cores, and electric blue internal cubic outline and a pale lime green outer edge, but combined and a certain angles, the crystals look teal blue-green overall and sometimes with a purple hue to their edges. A few areas of greyish-white Baryte (no crystals) are seen on the surface of the Fluorite. A really high class Okorusu mine Fluorite.
