The Miguel Romero Collection of Mexican Minerals
Oct 12, 2019
This particularly outstanding collection of Mexican minerals was put together over the years by Dr. Miguel Romero, and includes several of the most wonderful Mexican mineral specimens ever dug out of the ground, some of which indeed are widely recognized as the best mineral specimens from anywhere (so-called “mineral ikons,” using the term recently proposed by Wayne Thompson).

Copper Queen Mine, Bisbee, Warren District, Arizona
Sep 4, 2019
The Copper Queen Mine was first discovered in 1877, and ever since, the history of this mine rivals the drama of an old western. Silver and copper deposits were reported in the early 1870s, and in 1877, rich outcrops were found for prospectors to dig into. To set the stage, the Copper Queen Mine is situated, in what was then, hostile Apache territory in Arizona, and the U.S. Calvary patrolled the area. One day, they were searching for water in a canyon in the Mule Mountains of Southeastern Arizona, when they noticed outcrops that were tinted red with iron.

Benitoite Gem Mine of San Benito, California
Apr 3, 2019
The Benitoite Gem Mine filled one of the largest voids in the mineral world in spectacular fashion. Hessel predicted the ditrigonal dipyramidal class of crystallization in 1830, and when minerals were found in San Benito County in 1907 with this crystal habit, his hypothesis was confirmed. Only a handful of ditrigonal dipyramid minerals have been recognized to this day. This new mineral, named Benitoite, formed in triangular-shaped crystals with an intense sapphire blue-color.
