Another singular thumbnail, this specimen consists of a single scalenohedral "dogtooth" of Rhodocrosite that is affixed to a black acrylic base with hot-melt glue- removing it should be done with care. This crystal is almost complete, as a small area near its base was cleaved off, making it rest at an angle. The only other damage done to it is at its termination, where it seems that all three of the tiny basal terminations at the tip may have suffered some damage, one to the extent that an entire face is cloven off so that it appears unnatural but clean. The specimen has a pearly to waxy luster that is caused by a subtle and unusual natural texture on the main faces of the crystal. This texture interferes with the transmission of light through the crystal, which is surprisingly transparent-- one can easily see internal fractures througout the lower 80% of its length, and the upper 20% appears to be flawless. Needless to say, it has a deep pink color. One of the visible internal fractures near its base has a brownish color, likely due to a foreign material trapped in it. There is a tiny amount of black matrix visible through the crystal, likely a manganese oxide. Even with the damage, this is one of the nicest Rhodo crystals for its size that I have come across.
