Olmiite — The Crystal Circle

Once regarded as Poldervaartite, this mineral was later known to be Olmiite due to a higher concentration of Manganese than originally observed. This piece shows unique, bright barrel-like crystals on a matrix covered with druzy calcite. It is mounted on a 1 1/4" acrylic base (not pictured). There is a small ding on the mid right section of the piece, which is easily seen in the pics. Overall, a good sample of this interesting mineral.
