Four very LARGE, intergrown cubic crystals of a transparent to translucent, deep rich cobalt blue Fluorite. The large cubes have 4 mm wide gemmy vivid blue phantoms along the edges with the center top crystal being 4.0 x 3.8 x 3.2 cm. The internal center of the Fluorite is a cloudy white to off-white color with glimpses of the white brownish matrix engulfed within the Fluorite. This can especially be seen looking down into the top of the center crystal. There is contacting along the back and side of the piece with some corner and edge bruising observed. The crystal on the right is incomplete, as is the base corner of the adjacent crystal. While these are visible in the display view, I'm willing to overlook these imperfections due to the overall crystal size, luster, and magnificent color of the piece from this locale. It fluorescences a dark purple. The blue hue varies depending on lighting but shows it’s most brilliant color under cool LED lights. An uncommon large crystal of fluorite with a fantastic blue color saturation.
