MELLITE, Csordakut Mine, Tatabanya,  Hungary

A pair of connected brown xls, well formed and with decent luster, the largest 22mm across. That's just under an inch, and that is a good sized mellite xl. One corner of the main xl is missing, and there is one other contact, otherwise nicely formed. Nice blue FL under SW. An unusual mineral, found in coal mines, perhaps a half dozen localities known. TN, $75
