* Buergerite >

Buergerite is a rare member of the Tourmaline group. It was first discovered in 1966, and its locality was subsequently forgotten until the noted Mexican mineral collector Dr. Miguel Romero hired two exploration geologists to search and find the deposit. Subsequent finds have yielded very little material, and good specimens of this rare form of Tourmaline remain difficult to obtain. Buergerite is named in honor of Martin J. Buerger (1903-1986), a prominent mineralogist and professor of mineralogy at Massachusetts Institute of Technology.
