This is a crystal of very high quality and exceptionally high vibration.

It has optical clarity and amazing luster, with deep amethyst color at the bottom and stacked smoky and amethyst phantoms with an unusual and very rare shape, phantoms usually have triangular shape which is usually the shape of the termination of the crystal, but these phantoms are more round, which makes me believe that at those times the phantoms were formed this crystal had a more flat termination but in its final growth stage ended with  the usual triangular termination. 
It also has amazing internal rainbows.

This Crystal comes from the famous Streep Mine, located in the Goboboseb Mountains, Brandberg Area, Dâures Constituency, Erongo Region, in Namibia.
