# SID-29, $30.00 Sold!
Dims: 2.18x1.62x0.83in (5.53x4.13x2.10cm) .... Wt: 1.70oz (48.0g) .... Loc: Kalgoorlie, Australia
This siderite specimen is slightly unusual, in that the bulk of the specimen is siderite, but there is an area of colorless crystals that are similar but I suspect are not siderite. Dolomite, perhaps? A loupe reveals several tiny pyrite crystals are embedded here and there.
# SID-30, $155.00 Sold!
Dims: 3.17x2.08x0.64in (8.06x5.29x1.62cm) .... Wt: 4.2oz (120g) .... Loc: Turt Mine, Turt, Maramures, Romania
A quartz cluster is covered by a thick druze of excellent siderite crystals. In the closeup photo, the dark spot in the center of the tallest cluster is the top of a long prismatic quartz crystal. There is very little damage to the specimen, except along the edges where it was separated from the host rock. Many small quartz crystals are visible on the bottom of the specimen, as well as several additional minerals.
# SID-26, $36.00 Sold!
Dims: 2.93x2.40x1.70" (7.43x6.11x4.33cm) .... Wt: 9.10oz (258g) .... Loc: Campbell Shaft (2400ft), Bisbee, Arizona, USA
This hand specimen is covered with a layer of siderite crystals, plus numerous botryoidal clusters. They are opaque and a red-brown color, with individual crystals too small to examine. They have an irridescent surface that adds sparkle to the specimen in hues of red.
# SID-27, $30.00 Sold!
Dims: 3.00x2.97x0.55" (7.63x7.54x1.39cm) .... Wt: 4.66oz (132g) .... Loc: Campbell Shaft (2400ft), Bisbee, Arizona, USA
This is a flat hand specimen of siderite. Both top and bottom are covered with a druze of siderite crystals, some areas of which are red, some gray. The gray crystals appear translucent, and these provide a great deal of sparkle and a pleasing optical effect on the surface. A loupe reveals that the top surface consists of thousands of small botryoidal formations, each of which displays consistent crystal faces with an iridescent reflection.
