An extremely uncommon U.S. gem material and one that we have only been able to offer once or twice. Witherite is a barium mineral that doesn't often form with sufficient clarity to facet. One locale that does produce gem rough are the well known mineral deposits around Cave-In-Rock, Illinois. This fine example, is very well cut and translucent for the material, and is certainly a larger stone for the species as well. An experienced hand has given it a very fine polish for a mineral with a hardness of 3 on the Moh's scale. As is expected with this material, it has a chalky bluish-white fluorescence under UV light. Quite uncommon, even within 'rare stone' circles.
