This specimen is notable for several reasons. On the one hand a very nice franklinite octahedron, an unusual iron and zinc oxide, with good size, and curved and brilliant faces (17 x 17 mm). On the back side it has some fractures that allow us see the metallic luster. On a matrix of calcite. On the other hand, we have a doubly terminated prismatic crystal of willemite, also with good size (17 x 10 mm). Willemite species usually presents fluorescence, and in this case, under shortwave UV light (also in the longwave UV), it has an intense yellowish green color. Calcite from Franklin is also notable for the intense red-orange fluorescence. In one specimen we have two species with good crystals and size.

A huge size and top quality "Jackstraw" cerussite specimen. The "jackstraw" habit consists of numerous randomly oriented elongated crystals. The best known locality for this "jackstraw" type are those specimens from the Flux mine, in Arizona.
It is formed by a rich group of elongated cerussite crystals with an intense white color, divergent growth and good brilliance. In a limonite matrix. Both sides are mineralized. A classic specimen from this American locality. It was adquired by Gerard Vogel (Netherlands) in 1961, in California.

Elegant crystal of amazonite, a variety of microcline, good size, from a classic American locality. This crystal shows many faces delimited by triclinic pinacoids, along with growth in the upper faces. Good color and transparency when the light hits on the edges.

It is a brilliant smithsonite specimen from a mine not well represented and very uncommon in the collections, including the American collections. These zinc carbonate crystals show a polysynthetic growths of rhombohedrons, color between white to colorless, with a strong pearlescent luster and forming botryoidal aggregates. They are accompanied by blue-green rosasite, in spherical aggregates.
This specimen is interesting for different reasons. The accompanying old label belongs to the Antigua Casa (former house) Soler Pujol of Barcelona, ​​known for its collections relating to the natural history sciences. We add to its history that this specimen was in the collection of Mr. Lluís Daunis, also from Barcelona. An old specimen from a interesting American locality.
