This octahedral Diamond crystal has a few unusual traits. One half of it retains the traditional octahedral form, but the other half has that of the trisoctahedron, wherein each octahedral face is divided into three smaller faces and is slightly domed. I have not seen such an occurrence in a Diamond crystal before this one. The crystal is in excellent condition, showing little, if any damage, and has a good though slightly rounded form, with moderately well-defined edges and striated but clean faces that possess the standard adamantine luster. The crystal has a very pale brown color that jewelers might call "champagne", and is quite clear, though the striations on its surface provide considerable interference. Like all of our Diamond specimens, this one has no accompanying Kimberlite host rock.
