Description

This super aesthetic and rare specimen is from the 2014 discovery in the erongo mountains.

The unique dark blue color, barrel shaped form and association with schorl and pink topaz are definitive features of the find. The topaz are double terminated and well isolated the largest of which is positioned right on the termination of the smaller aquamarine. Some topaz are partially included in the beryl evident from the contacted underside.

The aquamarine has a good luster and zero transparency due to the saturation of color.

Study is still being undertaken to understand why the color is so dark.
