Look how striking these bright green fluorites appear against the stark black of the schorl tourmaline here! The tourmalines are compound crystals composed of dozens of acicular sub-crystals stacked tightly together, with a myriad of sub-terminations evident on top. The Erongo locality is best known for its aquamarines with schorl, but has also produced a limited number of these pretty green fluorites, and here the association with the schorl is really aesthetic.
