GARNETS
Today, we are presenting Garnets from three localities:

Two purple-red Almandine garnets in green Chlorite schist are from a now closed Alabama, USA locality. These are flashy specimens which are much better than the photos depict.

A nice Calaveras County, California Andradite collected in the 1980s by the prolific California field collector John Seibel.

Finally, there are over a dozen Grossular garnets of uncommon colors from Sierra de Cruces (Lake Jaco) in Coahuila, Mexico, and 4 specimens of the rare bright-red garnets from the far south part of this same area.

Sierra de Cruces, Coahuila, Mexico has been inaccurately known since the 1950s as Lake Jaco, and has produced many colors of Grossular garnets. In December 1992, Graham Sutton and Bob Griffis discovered a small outcrop of bright Red garnets in a stark white matrix from an isolated hill (Cerro de Moka) at the south end of the Sierra de Cruces mountain range. The garnet-bearing outcrop was at the top of the hill and was completely removed over 2 field trips. The largest garnet crystal found was approximately 7 cm and resides in the Pohl collection at the Freiburg Museum.
