Gaudefroyite is a very rare manganese borate compound. Lustrous, black, hexagonal gaudefroyite prisms to 8 mm are richly strewn on this fine example of the gaudefroyite/andradite/baryte combination specimens. The gemmy, bright to dark cherry-red andradite garnets are a nice compliment, as are the snow-white barytes. The best gaudefroyites in the world come from the Kalahari Manganese Field and this is a highly representative and fine example of the combination species. Ex. Wes Parker Collection.
