Ojuela Mine, Mapimi, Durango, Mexico
Thumbnail, 2.3 x 1.0 x 0.6 cm
Ex. Irv Brown

A superb single crystal of legrandite with an unusually broad, well developed termination compared to the often-haggard-looking style of most legrandite tips. This is a competitive thumbnail, for the shape, termination, and shocking electric yellow color. Others have all three qualities but more than that, it has the best almost-metallic luster that you see on only one in 100. Ex Irv brown thumbnail collection.
