In general, the BMC meets at 7:00 p.m. on the first Tuesday of every month in Haller Hall in the Harvard University Museum of Natural History building in Cambridge, MA. Each meeting features refreshments, a speaker from the mineral world, and a mineral specimen raffle. Visitors to our monthly meetings are always welcome!

Of course, there’s more to it than that….
