This specimen is a beautiful boracite from extremely deep finds in this huge mine, found in the mid 1990s. They are now remembered for their beauty and this is no exception. Perched aesthetically on matrix of orange hilgardite is a cluster of lustrous and translucent, pastel green crystals up to 3 mm in length. Note the complex, mesmerizing, triangular look to the crystals... very different from boracite from other locales like Germany or Bolivia. I have seen many fine larger pieces (though, few recently) but this is perhaps the most elegant thumbnail example I have run across. Complete all around.
