TP27AH4: Very aerial aggregate of Pyromorphite crystals with very well defined faces and edges, some of them doubly terminated and others with very well defined hollow growths. They are bright and have an excellent color. An American classic, not only of great quality but also different than usual for this extraordinary mine.

VD59Y3: Group of crystals on matrix, with a very well marked barrel-shape and vivid orange color with the intense luster typical of this type of sample from the Bunker Hill Mine. As a rarity, we note a coating of a second generation of yellow crystals with a prismatic shape and very well marked curvatures of faces and edges. While this type of crystals is described as arsenical, nor by the bibliography or by analysis we have done previously, we know that this is so.
The piece is from the Harjo Neutkens collection, whose label we’ll send to the buyer.

TB96C8: A large monster! A huge crystal standing on the top of a matrix that is made up of other huge Pyromorphite crystals. The form is excellent and the color is very agreeable as it is turning towards golden brown. Everything complete, a floater and, as the photo shows, excellent!

TC63AH1: Group of Pyromorphite crystals with very well defined curvatures that give them a barrel habit. They have an excellent orange color and luster. Although it has been reported that this kind of globular orange crystals from Bunker Hill are arsenic-rich Pyromorphite specimens, we analyzed some samples and the results are that they really are pure Pyromorphite, with no arsenic.

EJ17AM1: Druse on matrix with two generations of Pyromorphite with different characteristics, an earlier one with spheroidal growths of small crystals, with good luster and orange color, and the second with larger crystals of pyramidal habit and with geometric growths around the terminations, lustrous and greenish-yellow. A high-quality American classic.

TR26Q1: Sharp twinned crystals with very well defined crystal form, transparent and of excellent luster. We especially note the locality, now abandoned, that produced good but scarce specimens of this species.

MBA56AP2: Multiple twin of sharp shiny Cerussite crystals, flattened, between transparent and translucent. The specimen, from a mine well known for its pyromorphites but in which quality cerussites are rare, comes from the collection of Thomas P. Moore and we will send it to the buyer with its original Perky box.
