Everyone should have an ugly duckling in their collection and this piece fits the title. It has loads of the hornblende crystals which are all surrounded by small sparkling books of biotite mica. There is "discussion" among collectors that this is really the mineral
Fluo-magnesiokataphorate as some chemical tests supposedly have shown.
