An excellent thumbnail specimen of **terminated** grandidierite. It is nearly impossible to find examples with visible terminations.

In 2016 there was a rather spectacular find of this very rare blue-green borosilicate mineral in southern Madagascar. I has seen some available on my previous trip, but the quality was horrible-- they were basically formless shards, and few if any had crystal faces.

There was a little bit more available this time around, but once again, the majority were shards. Still, I looked through them and was able to obtain a small number of pieces that had visible crystal faces, or even a termination-- this one has both and is quite exceptional. This is probably one of the top two thumbnail sized examples of this material that I am offering.
