Larger specimen of pinkish red Hureaulite in masses and crystals to 3mm with cavities filled with sugary lime green Tavorite and clusters of well-defined, excellent crystals in groups to 2mm. These are fabulous crystals of Tavorite, some of the best around. At the Tip Top mine, Tavorite is uncommon and crystals are very rare. I'm not sure if there is a better locality. Scattered around the cavaties to a lessor degree are tiny less than 1mm opaque yellow-orange Ushkovite crystals, deep red Bermanite and purple Leucophosphate crystals.
