The classic, and quite famous, San Francisco Mine combinations of Wulfenite and Mimetite only came out in the 1970s and in the early 1990s, with this particular piece having been collected in 1994. These excellent Wulfenites are of a character that you don't normally envision when thinking of the San Francisco Mine. It is unusually robust and has a butterscotch color, more than the usual yellow or orange. These choice crystals are translucent to gemmy, with an incredible, glassy luster. The form is complex, with beveled edges AND tiered, architectural faces. The largest crystal is about 2.2 cm, and they are associated with perhaps hundreds of yellow to greyish-yellow, mm-size Mimetite balls. Thick and robust for the locality, the Wulfies are in excellent condition. Showy and superb, this is an exceptional Wulfenite, no matter what the locality. NOTE this cannot be mailed.
