7.5 x 5.5 x 2.7 cm. A classic, curved, "ram’s-horn" gypsum crystal from the Southwest Mine at Bisbee. The termination is covered with a multitude of tiny gypsum crystals. Complete-all-around and nearly pristine. Very uncommon from this noted locale and very similar to classic Mexican material.
11.5 x 8.5 x 5.8 cm. Beautiful, glassy, golden-amber gypsum blades comprise this striking, sculptural, solid cabinet crust of gypsum from the Las Salinas deposit of Peru. A single, 1.3 cm, classic, fishtail-twinned crystal prominently juts out from one corner. Ex. Robert Fender Collection.
15.9 x 13.0 x 12.8 cm. An impressive, large cabinet, stellate gypsum crystal cluster from a very uncommon Maryland locale - St. Mary's County. The gypsum crystals are preferentially clay-included. The lustrous, large blades, to 6.8 cm, have transparent edges with clay-included interiors. The blades are attached to a large, intergrown ball of smaller gypsum crystals. This dramatic piece bears a strong resemblance to the famous golden gypsum bladed balls from the Red River Floodway of Manitoba, Canada, except for the color. This is a very rare, complete-all-around floater that is essentially pristine. An interesting Maryland rarity from the Robert Fender Collection and dates from the 1960s or 1970s, possibly much earlier. We have never seen a Maryland gypsum of any type before, come to think of it.
6.3 x 4.8 x 3.4 cm. A very nice and showy doubly terminated gypsum crystal from Bulgaria, rare for the locale. Most of this striking, waxy lustre, water-clear, parallel-growth crystal is colorless, but one termination is faintly yellow. Complete-all-around and pristine. I have never seen another gypsum from Bulgaria like this. Ex. National Museum of Natural History - Sofia.
A gorgeous specimen with really rich coverage of Paratacamite , to 1 mm or so, on matrix of sparkling quartz infused with blue chrysocolla. Selenite, which you can look right though, caps off the protected vug! 5 x 3.6 x 1.2 cm
10.1 x 6.6 x 6.3 cm. Lustrous, forest-green paratacamite crystals to 3 mm richly line a well-placed vug in the cabinet quartz matrix and are in stark contrast to the water-clear gypsum blades adjacent to the right. This specimen is from the one-time, 1998, Gladys Pocket in the Lily Mine of Peru.
A pretty “flower” of pastel pink manganocalcite (the manganese content tints it pink) accented by silky crystals of translucent selenite. 4.0 x 3.2 x 2.9 cm
Perched on a bed of tiny gypsum crystals, which in turn is on a matrix of massive gypsum, are three transparent spears of Selenite to almost 4 cm. This cluster is extremely aesthetic. These were once available in the early 90s in some quantity but i have seen few in recent years and am told that the quarry has not produced them in almost a decade. OK, so it is "only selenite" to some folks but , species interest level aside, its just aesthetic as all getout and some of the prettiest, sparkliest mineral specimens on the planet 6.1 x 5.5 x 4 cm
An EXCELLENT, showy, lustrous and translucent, doubly terminated gypsum crystal from an uncommon locality in Alberta, Canda. The sidecar crystals add character to this fine piece. A super-trivial bruise on one termination is barely noticeable. Ex Marty Lewadny Collection of Winnipeg, Canada. 9.5 x 4.3 x 4.2 cm
An showy piece of a sharp, water-clear, pristine, lustrous, light amber selenite crystals to 2.2 cm attached to matrix. This Spanish locality, Roden, is now defunct and these are seldom available. The base has been sawed to enhance display. CHOICE material from the Lewadny Collection. 5.8 x 4.2 x 2.3 cm
This is BY FAR, the FINEST, LARGEST and BEST, Mission Mine, Arizona micro-dendritic copper in a transparent gypsum cleavage slab that we have offered at auction. This large, bladed CABINET specimen compares very favorably with anything that has been in the Gallery. Old and very choice material we do not see except in old recycled collections, as well. Ex Evan Jones Collection. 13.2 x 7.7 x 1.0 cm
An EXCELLENT and showy cluster of VERY LARGE and THICK, lustrous, transparent, light amber selenite blades from an uncommon Canadian locality. Trivial termination bruising on a couple of the crystals in no way detracts from the beauty of this fine Lewadny Collection piece. 9.5 x 5.9 x 5.7 cm
An BEAUTIFUL curved vug filled with sharp, water-clear, pristine, lustrous, light amber selenite crystals to 2.8 cm attached to massive gypsum matrix. This Spanish locality, Roden, is now defunct and these are seldom available. CHOICE material from the Lewadny Collection. 7.0 x 4.2 x 3.6 cm
Delicate and very attractive pseudomorph in which the Gypsum is perfectly replaced by the Goethite. Each sharp blade shimmers with a green or red iridescence that gives this excellent thumb a beauty all its own. 2.4 x 1.9 x 1.2 cm
A superb example of a normally prosaic variety of this species! This is easily one of the best and largest specimens I have seen from this deposit. The largest, doubly terminated, crystal is 16 cm across. Although the crystal centers are sand filled, the crystal edges are translucent. There seems to be either a repair or stabilization at the junction of one of the larger crystals to the cluster. It is hard to see and does not really detract from teh piece at all in terms of display quality. Besides the dimensions, this specimen exhibits extremely aesthetic crystal arrangement. 16 x 13 x 9.5 cm
