An unusually thick and weighty specimen, much mor erobust than most, with thick secondary crystallization along most of the lower part of the spinel twin, wrapping around the piece. The clear lines of the central twin emerge from the upper half, and the central twin line has several sharp flanges to give it added visual impact and size appeal.
