These pyrites with incredible luster and a sharp crystal habit, turned up in early 2014 at the Chivor emerald Mine in Colombia. Although not the biggest, many people consider them among the finest pyrites ever found for their size, for the complex habit and shocking bright luster. They are perched on sharp dolomite crystals, which is also unusual. Many had substantial damage, but these were carefully trimmed out form larger pieces that survived. This piece features crystals to 2 cm, and many dozns of smaller ones sparkling in the dolomite matrix.
