One singularity in appraising the desirability of a specimen is form. When a crystal form shares a common axis it twins. Rarely, will a crystal twin in multiple directions. This piece is doubly twinned with equant faces. It is highly reactive to long wave. A must have for the collector of single crystals or twins.
