Mogok, Burma (Myanmar.)

Zinnwald, Bohemia, now Cinvald, Czech Republic.
Measures 1-3/8x1-3/8x1 inches. An exceptional. old-time group of “gun-sight” crystals with no matrix. The locality is now called Cinvald, Czech Republic. I have never seen a finer example. This specimen came to me first around 1960. I sold it at that time to Alex Mann from whom I reacquired it on March 10, 2003.
