It is hard to find a good cluster of Danburite. Usually we see them as single crystals, and occasionally as large clusters, usually damaged. This cluster is quite aesthetic as the crystals shoot off in many directions. Near the base of the crystals are reflective Chalcopyrites. Danburite is found in a Tin Mine in Mexico. The miners that bring them out are apparently quite rough with them, as seen by very common damage. This piece is in good shape overall. the largest 15 crystals are fully intact, there is a stub or two, but you have to look for them.
