A spectacular hemispherical cluster of radial quartz crystals colored green by hedenbergite inclusions, some capped by greenish-white calcite.
There is not a single broken crystal anywhere on the display face, which I credit to the thicker-than-usual crystals-- the examples I have seen in the past are typically composed of much narrower crystals, meaning that there is almost always damage.
This is admittedly not cheap, but it is exquisite. If you are a collector of Chinese minerals or are putting together a suite of Inner Mongolian specimens, This would be a good one to consider. I have seen thousands of quartz specimens from this mine, and hundreds of hedenbergite included pieces, and this one stands out in both categories.
