A translucent to transparent, twinned gypsum crystal. This specimen is complete all around, with no point of attachment to matrix. The terminations are somewhat hollow. Very minor rubbing, which is expected for such a soft mineral (Mohs hardness = 2) and that was collected (according to my notes) in the 1970's. Point Dume is a famous Hollywood set locality, having been featured in such as the Statue of Liberty scene in the original Planet of the Apes, or the deserted Pacific island (and home of Jeannie's bottle) in the pilot of the TV show I Dream of Jeannie. A must-have specimen for the collector of gypsum, California specimens, or famous locality specimens. Eerie internal blue fluorescence under both longwave and shortwave ultraviolet.
