2.5 x 1 x 0.5 cm. This is a fine pseudomorph. The Sturmanite, which replaces what appears to be extruded Gypsum, has a very nice color and superb luster. Ex. Willy Israel Collection.
7.5 x 0.9 x 0.7 cm. An old Naica specimen with a Hugh Ford label - a clear, slender, doubly-terminated crystal with unidentified inclusions. Ex. Carlton Davis Collection.
6.6 x 3.8 x 2.1 cm. Eye-visible, large-for-species, GEMMY, crystals of sklodowskite perched on contrasting matrix of gypsum. Crystals are 2-4 mm in size with a bright neon yellow color. Ex. Martin Zinn Collection.
7.8 x 5.4 x 3.9 cm. On this 3-dimensional knob of matrix is a bed of glittering crystals of azurite. There are traces of a green copper mineral, and on one side of the specimen, a complete, terminated and transparent crystal of selenite sticks out from the matrix. Ex. Dave Stoudt Collection.
9.9 x 4.2 x 1.1 cm. A fine specimen of bright, micro-dendritic copper in a sawed, transparent gypsum slice from the Mission Mine of Arizona. Ex. Stoudt Collection.
4.9 x 3.1 x 2.9 cm. This is a razor-sharp pseudomorph of gypsum after flattened rhombs of glauberite, an old-timer specimen from Camp Verde in Arizona.
17.8 x 9.1 x 6.8 cm. This is an old German selenite, out of the collection of Marty Zinn. The glass-clear anchor crystal is complete and doubly-terminated. Along its sides smaller crystals spray out beautifully in every direction.
7.6 x 7.2 x 5.9 cm. This beautiful and unusual specimen has a core of glassy and colorless gypsum crystals up to 1 cm in length. A druse of royal blue azurite, to .5 cm in length is on the smaller gypsum crystals and included within the larger ones. Ex. Harold Urish Collection.
17.5 x 12.5 x 10.2 cm. This is a huge, really stunning selenite crystal from a U.S. locality. This is a super-transparent crystal with a silky luster and frosted faces on the side. Though it is 3.5 cm thick, you can easily read right through it.
6.5 x 6.0 x 3.8 cm. A ball of twinned crystals of selenite, with two golden, gemmy crystals protruding out from the rest - from the clay beds of the Red River Floodway near Winnipeg, in Canada.
10.9 x 7.8 x 6.9 cm. Sparkly pyrite covers strange narrow, peak-like crystals of elongated pyrrhotite (classic for the locality, but rare in this replacement form by pyrite), with little snowballs of gypsum scattered here and there for accent. Ex. Dave Stoudt Collection.
A gorgeous CABINET specimen of lustrous and transparent golden amber selenite crsytals to 3.0 x 1.8 cm on halite matrix from the Pisco Mine, Ica Department, Peru. Absolutely minimal damage to this beautiful specimen. One of the better large specimens we have seen, in particular because it preserves the halite association (many of them get dissolved away in situ). VERY SPARKLY and colorful, MORE SO IN PERSON. 16.5 x 9.0 x 6.5 cm
A showy specimen of lustrous, water-clear well-terminated selenite crystals to 2.5 cm attractively perched on the top of mostly massive pyrite from the famous Darwin Mine of California. One well-formed and striated pyrite cube stands out. The long selenite crystal has hole through the crystal at the termination! This is older material, seldom available, as the last portion of the Darwin Mine closed in 1976. See the Mineralogical Record article in the January-February 1984 issue. 6.8 x 5.8 x 3.5 cm
9.8 x 6 x 4.1 cm. This is a large well-formed fishtail gypsum twin. The luster is excellent and the edges are as consistent and sharp as you ever find them in Gypsum. The twin is actually much gemmier than can possibly show up in the photo because of the twinning and well-defined internal planes.
6.5 x 4.1 x 2.5 cm. A fine and unusual Spanish specimen of three lustrous, red quartz crystals embedded on Triassic gypsum from Teruel, Aragon, Spain. The two large crystals are doubly terminated, with the largest being 1.6 cm. The piece dates to the 1970s. Ex. Richard Hauck Collection.
