This specimen is composed of well formed fingers of very lustrous, translucent, light apple-green, prehnite after anhydrite. The fingers reach 4.25 cm in length and one can see the empty casts on the bottom that once contained anhydrite. A very aesthetic, 3-dimensional piece with depth of field to its view, this is one of the larger specimens recovered in such good condition (all stalactites are complete except only the minor one at bottom). Such pieces were previously seen only from old collections and museum deaccessions
This is a magnificent, large, cluster of fingers of prehnite to 7 cm in length. Out of all of them, over a dozen, only one minor finger in the middle is broken off (and it is picked back to the contact so you only see it from the side view, anyhow. It is in pristine shape otherwise, complete all around and extremely 3-dimensional and space filling. The fingers of prehnite are all very lustrous and translucent with a superb, light apple-green color. One small 5 mm crystal of colorless calcite is perched between two fingers of prehnite, for a minor accent. The bottom of the specimen exhibits clear evidence of hollow casts, showing how the prehnite formed atop of and after what were once anhydrite crystals. A layer of calcite grew over part of the bottom, as well (photo on request). This is one of the largest pieces recovered in this quality, nearly pristine and without any repairs. It is thus a major New Jersey specimen, or US prehnite specimen, and for size and impact has a great presence as well.
Clearly a major plate , featuring varying shaped fingers of prehnite to 5 cm in length, this specimen is pristine and 3-dimensional with a superb sculpted appearance. The largest crystal, though, shows the straight lines of the anhydrite replacement more closely and preserves the original crystal habit with better fidelity. The prehnite has super luster, translucence, and a fine light apple-green color. Additionally, a few lustrous and translucent, colorless crystals of calcite, to 1.5 cm in length, are perched up on one edge of the specimen. Evidence can be seen of hollow casts after anhydrite on the bottom of the specimen, showing how the prehnites developed by casting or as an overgrowth upon those original anhydrites. The piece overall is extremely dramatic and showy , and the variety and 3-D nature of the different crystal habits is appealing in person - quite different than others here in its variety of forms, I think.
Lustrous and translucent, light apple-green fingers of prehnite, to 4.5 cm in length, smother a matrix plate here. The piece is dramatic and 3-dimensional. It features a particularly robust crystal in the middle, about 3.5 cm across and about 1.6 cm thick, that stands out in isolation for size and thickness. On the bottom of the specimen you can see clear evidence of how these formed over the now-hollow casts that were once anhydrite. The color here is good, though a small amount of thin matrix adheres in some places. Great sculptural form as well as super luster make this cabinet piece an important example, and it is complete all around
Prehnite fingers on both sides of this specimen converge to form an aesthetically pleasing and sculptural, 3-dimensional appearance. The fingers are very lustrous, translucent, and with a light apple-green color . They reach 4 cm in length. Hollow casts of what were once anhydrite are clearly in evidence underneath. Complete all around!
A crust with smaller fingers is surmounted by a majestic single spire of very lustrous, translucent, light apple-green prehnite, measuring 5 cm in length. Actually this piece is for some reason just a slight bit more yellow than its pocket brethren , in person. A few small lustrous and translucent, colorless crystals of calcite, to 1.2 cm in length, are scattered about the specimen for accent. The bottom face shows evidence of hollow casts of what were once anhydrite. This is one of the most balanced and attractive of its sized specimens here, and is very 3-dimensional and complete. Perhaps my personal favorite among teh more isolated "fingers" here
One of the most dramatic large pieces recovered, this plate has no repairs and is complete all around. It features three, large, upright, lustrous and translucent fingers of apple-green prehnite, to 7 cm in length . They are perched above other nubbier fingers and splay in all directions. A single, lustrous and translucent, colorless, calcite crystal measuring 1.9 cm in length is jauntily perched on the side of one prehnite finger. The bottom face clearly exhibits hollow casts to show that these were were once anhydrite crystals, now crested over by the prehnite which remained when the anhydrite dissolved away. In particular, please note the superb hollow cast that transverses the length of what is now a prehnite finger. Amazing!
Multiple fingers of super-lustrous, translucent, light green prehnite to 3 cm in length make up this attractive specimen. It is one of the most aesthetic in its size range, with lots of sparkle and depth. The bottom clearly exhibits hollow casts of what once were anhydrite. For the rest, it is complete all around and elegantly displays on a custom base
A single spire over 7 cm in length that is very lustrous, and translucent with a light apple-green color, is the highlight of this prehnite. The bottom face clearly exhibits a window into the hollow cast of what was once a large anhydrite crystal. Unusual style for the pocket.
DRAMATIC complete-allaround specimen with somehow a more powerful visual impact than the other pieces here with isolated crystals. This is an aesthetic prehnite specimen where a single, very lustrous, translucent, light apple-green finger rises majestically between two smaller fingers. Additionally, ther are two lustrous, translucent, colorless, calcite crystals, to 1.25 cm in length; the larger of the two being doubly-terminated. A view up the bottom clearly exhibits hollow casts that used to be anhydrite.
One of our absolute favorites of the lot and perhaps the best of the smaller small cab specimens for its elegant form. This is an aesthetic cluster of very lustrous and translucent, light apple-green prehnite fingers, to 4 cm in length. In fact, the specimen looks like a cityscape. The specimen is undamaged and complete all around. Interestingly, hollow casts of what were once anhydrite are clearly evident from the bottom view. Superb!
A spectacular large-miniature combo specimen,with fingers of very lustrous and translucent, light apple-green prehnite to 3 cm in length enhanced by a doubly-terminated, lustrous and translucent, colorless calcite crystal measuring 3 cm in length. I particularly like the way the largest prehnite finger is rotated away from the viewer while the calcite is rotated toward the viewer, making for depth of field. The bottom face clearly exhibits hollow casts of what once were anhydrite. Simply among the most aesthetic pieces here!
The fingers of very lustrous and translucent, light apple-green prehnite, range in size and shape from nubs to delicate, elongate appendages up to 4.25 cm in length.There is no damage or repair to any of the prehnite fingers, unlike classic old museum pieces of this style. The bottom face exhibits hollow casts of what were once anhydrite. In the photos, the piece shows less relief than it does in person because it is actually quite complex and 3-dimensional when you see it in person. A beautiful piece, very large and dramatic.
