Blocky, light green glassy crystals of Datolite, partly coated with microcrystals of Apophyllite and Arsenopyrite. I bought this from a well-known Dealer at the 2006 Tucson Mineral Show and was asking him what were the black microcrystals on the specimen. Although not labeled, he thought it was Arsenopyrite, but turned around and asked a gentleman standing outside the booth, who turned out to be Bill Smith, himself. Bill confirmed that is was Arsenopyrite and I got hold of his original inventory card, which traced back to where he obtained the specimen. This is a great specimen and the photos barely do it justice.

The name Aurichalcite probably comes from the Greek word oreichalchos meaning "mountain copper". This specimen is richly covered with radial clusters of Robin's egg-blue, acicular Aurichalcite crystals
One of the Tungstates of iron and manganese, the two elements form a continuous Wolframite series in which the end-members are known as Ferberite and Hubnerite, both are important ores for the extraction of tungsten.
The Lady on the Mountain is a rock formation on Magdalena Peak overlooking Magdalena. Spanish soldiers saw the face of a woman on the west face of the peak. A priest with them was reminded of a similar peak in Spain called "La Sierra de Maria Magdalena", so he called the New Mexico one "La Sierra de Magdalena". The natural pass to the south of the peak became known as Magdalena Gap, and when a town grew up it received the same name
A large, impressive doubly-terminated, lustrous Calcite crystal over 18 cm in length sitting on a matrix of euhedral Calcites with iredescent, glimmering Chalcopyrites in metallic hues of purple and blue. One of the terminations has some minor damage, but not visible from the front and not really overcoming the beautiful presence of this specimen from Missouri.
A rare intact and large pocket containing shimmering globes of pale blue Smithsonite from the famous Kelly Mine. These globes measure up to 1.8 cm across. A couple are dinged, but the specimen is in overall very good condition. Specimens of this size and quality are just not that available anymore.
Wow! A super 5 cm hexagonal tabular light blue Aquamarine crystal in the middle of a Muscovite crystal covered matrix. The large crystal is gemmy with complex jagged modifications on the display face. Other minor Aquamarine crystals are nearby. Excellent quality and a great deal for the price.

The name pyrite is from the Greek word "Pyr" meaning "fire". This is likely due to the sparks that result when pyrite is struck against steel. This capacity made it popular for use in early firearms such as the wheellock (From Wikipedia, the free encyclopedia.

Amazonite (sometimes called "Amazon stone") is a green variety of microcline feldspar.
The name is taken from that of the Amazon River, from which certain green stones were formerly obtained, but it is doubtful whether green feldspar occurs in the Amazon area.
Amazonite is a mineral of limited occurrence. Formerly it was obtained almost exclusively from the area of Miyask in the Ilmen mountains, 50 miles southwest of Chehabinsk, Russia, where it occurs in granitic rocks. More recently, high-quality crystals have been obtained from Pike's Peak, Colorado, where it is found associated with smoky quartz, orthoclase, and albite in a coarse granite or pegmatite. Crystal Peak, Teller County, Colorado is a well-known locality for crystals of amazonite. Ethiopia is now a recognized source of quality specimens

Nice size twinned Amazonite bluish-green crystal from Ethiopia.

A complete and terminated light golden Citrine crystal with a fine glassy luster included with tiny acicular crystals of Jamesonite. There is a natural contact on the back of the crystal where it grew against matrix. Very bright and showy specimen.
The Southeast Region of Brazil is composed by the states of Espírito Santo, Minas Gerais, Rio de Janeiro and São Paulo. It is the richest region of the country, responsible for approximately 60% of the Brazilian GDP

Gorgeous specimen of bladed Muscovites standing upright on a shimmering bed of translucent, plates of Cleavelandite crystals.
This is an excellent pegmatite specimen from the F.J. Barlow Collection.
Though not a zeolite, Prehnite is found associated with them and with datolite, calcite, etc. in veins and cavities of basaltic rocks, sometimes in granites, syenites, or gneisses. It is an indicator mineral of the prehnite-pumpellyite metamorphic facies. It was first discovered in South Africa by Colonel Hendrik Von Prehn, an early Dutch governor of the Cape of Good Hope colony. Prehnite was the first mineral to be named after a person (From Wikipedia, the free encyclopedia).
Nice combination of light green Prehnite crystals with white to light pink Chabazite crystals on matrix from the classic New jersey location..
