This find was made a couple of years back in China, and is absolutely unique: glittery, golden pyrite microcrystals preferentially deposited on the edges of flattened, pastel-pink, manganoan calcite rhombs. The calcite rhombs reach 4.4 cm on this specimen. Some of the specimens had very sparse coverage of pyrite, just a salting, but here, it is richly carpeting the crystal edges.
