Ah this wonderfully clear raw Goboboseb Amethyst crystal, reminds me of the color of the sunrises over the Namib desert.
I have paired it with a raw pinkish Garnet from Tanzania.
The cap is sterling silver.  The crystal is 1.5 inches long and 3/4 inches wide.
The chain is 24 inches in length and is a sterling silver rolo style.
