Mimetite With Calcite
San Pedro Corralitos Mine, Casas Grandes, Chihuahua, Mexico
Small Cabinet, 8.5 x 6.4 x 3.3 cm
Ex. Lawrence H. Conklin
Here you have a dramatic, large, 3-dimensional specimen from a very rare and old find. It looks good from ANY angle and to be honest, I cannot decide which "front" I like better. It is good horizontal, sitting flat; or standing up vertical. The balls of crystals are also very large for the material, reminding me well of the famous Pellman specimen from this pocket. The gossan matrix is completely smothered by sparkling balls of botryoidal mimetite. The color is almost a saturated yellow, nearly the best you can get for the locality and considered more desirable than orange-yellow hues. It is brilliantly sparkling in light, and colorful and complete all around 360 degrees. As a bonus, there are little sparkly calcites perched here and there atop the mimetite balls - a very rare association for the pocket and one I have seen only a very few times before. ALL such mimetites as this were collected in a single large find in end of 1968 and start of 1969 by Benny Fenn (right before the Tucson show of that year!), from a one-time pocket at a small prospect. It was literally a small prospect, not even a developing mine, and it never panned out or produced more specimens again. Despite attempts to find another mimetite pocket, no more ever came out. These remain unique in the world for their overall aspect; and large, colorful pieces like this are treasured by those who have them. No other locality has produced mimetite of such aspect to this day. Even at the time, this would have been considered exceptional for its size and all-around aesthetics. Again, from my perspective, the color grade on this is particularly high, making it a choice specimen even among those of us who have seen many over the years. As a bonus, this piece has the history all the way back to when it came out, going through three collections - in reverse order being: Larry Conklin, the late John Marshall, and Karl Vossbrink. Offered now for the first time in over a decade. Joe Budd photos.
