WOW! This amazing, 2.25-cm cassiterite is a real killer by San Diego standards, where the mineral is exceedingly rare in the pegmatites. I have seen just a handful in collections over the years. It was recognized in early mining material by the Gochenours, who sold it to local collector Chuck Houser, and then eventually it ended up with Chris when he concentrated on a CG suite. It is a unique piece to my knowledge. The crystal is complet all around except for minor contacting on the right-upper edge. It is associated with minor tourmaline.
