MF47E7: From a locality that used to be very productive (although it is no longer so) this one stands out from all the others found there for various reasons: the form of the crystal (slightly oblong and with small octahedral modification on the corners), all the faces are undamaged, the brilliance of the faces, and, above all, its great position on the matrix of botryoidal Pyrite. So while many Galenas have been found in the Tri-State district this one is special.

Galena with Pyrite
 

TF76F6: A classic species, with the classic cuboctahedral form and from a classic locality. It started as a cube and then later on cuboctahedral forms grew on it, orientated to the cube. All of which makes the specimen especially attractive.

Specimen size: 5.5 × 4.5 × 3.5 cm = 2.17” × 1.77” × 1.38”

Orpiment

This was the main novelty from Tucson 2000. These were found in April 99 at the Twin Creeks mine, north of Winnemucca, Humboldt County, Nevada. Many specimens were found, but the majority of them were pale orange or yellow. The Orpiment was found in the 62 bench of the mine and the geologists seeing them decided to preserve them so they were removed manually with great care.
Orpiment is a stable mineral that does not alter over time, however like many other minerals it is sensitive to sun light so it is best to display specimens in darker areas of your display.

Octahedral Fluorite
 

TF48N9: Octahedral crystals of considerable size, very well defined with a deep and uniform color and good luster, which not so frequent in the samples of this locality.
The number mark on the sample indicates it was on the collection of John H. Marshall, well known collector of Pyromorphite but who also collected Fluorites.

MP27J0: Spherical growths of laminar crystals on a serpentine matrix. We especially note the rich green shades of the group. This Prehnite is from a classic locality and good specimens are very scarce today.

Specimen size: 11 × 8.2 × 3.7 cm = 4.33” × 3.23” × 1.46”

Prehnite with Datolite
 

TC47Y6: Very rounded, almost spherical, Prehnite crystals with a very clear green color on a surface of transparent and extraordinarily bright Datolite crystals with very well defined faces and edges and on a rocky matrix. A good American classic of which currently circulate very few samples.
This piece is from the Tichelman collection (num. 309) whose label we’ll send to the buyer.
Prospect Park Quarry, Prospect Park, Passaic County, New Jersey  USA (±1970)

TJ40AF7: Spheroids of almost white Pectolite with radial sections. On matrix with small pale green crystals of a not identified species (probably Datolite).
The sample is from the inventory of Charles Key and has a great quality for the species and the locality.
Millington Quarry, Bernards Township, Somerset County, New Jersey  USA

Specimen size: 9.2 × 5.1 × 5 cm = 3.62” × 2.01” × 1.97”

TV87AL3: Arborescent growth of flattened Copper, on matrix, very aerial, with poorly defined crystalline forms. High quality Coppers like this one are very rare in Franklin.
The specimen comes from the Rock Currier collection (No. 3070), whose label we will send to the buyer.

NA50Z7: Octahedral Franklinite crystals with very well defined faces and curved edges. The crystal, of good size, is free of damage which is rare for samples of this fragile species. It is on a Calcite matrix with red crystalline Zincite nodules.
Franklin, Franklin Mining District, Sussex County, New Jersey  USA

Specimen size: 8.1 × 6.8 × 4.2 cm = 3.19” × 2.68” × 1.65”

EXJ47AQ1: Lamellar Heindricksite crystals with very well developed crystal forms for the species, shiny and dark green, almost black. On matrix, with dodecahedral crystals of Andradite, the “polyadelphite” variety, which contains a wide range of elements.
The specimen, from the type locality for Hendricksite, comes from the Moutet collection, from Marseille, and is accompanied by an old label from Deyrolle, from Paris, which we will send to the buyer.
