Description

This very interesting specimen from Lower Austria features a well-formed ruby crystal, a variety of corundum, embedded in dark, graphite-rich matrix. The contrast between the reddish crystal and the dark host rock gives the piece a very distinctive appearance. Small veins of golden pyrite add additional visual interest and contrast. A remarkable mineralogical rarity from this locality.
