Here is another rarity we recently came across: dumortierite! The chemical formula for this borosilicate probably gives mineralogy students nightmares, although it certainly is a pretty mineral. Our specimen showcases radiating, lavender crystal sprays up to 2 cm in diameter contrasting nicely against matrix. This is our finest specimen from a lot obtained from our friend, the late Mike Clark (and likely self-collected by him decades ago).
