Bob Reynolds collection with his collection number and small plastic display stand attached to the back.
ST810 - Chlorargyrite $ 400 (=~ £ 320) Broken Hill, NSW, Australia miniature - 4.5 x 2.7 x 2.3 cm Coral-like growth of solid waxy, greenish Chloragyrite atop a small amount of matrix.
ST853 - Cavansite on Stilbite $ 275 (=~ £ 220) Wagholi Quarry, Pune Dist., Maharashtra State, India miniature - 5 x 4.5 x 2.5 cm Rounded clusters of electric blue Cavansite on Stilbite. The Cavansite clusters reach 1.5cm in diameter. The Stilbite occur as both tiny drusy crystals and larger white individual crystals. Undamaged.
ST859 - Heulandite, Stilbite $ 150 (=~ £ 120) Jalgaon, Maharashtra State, India small cabinet - 6 x 5.5 x 4 cm Large pearly white bow-tie clusters of Heulandite attached to a section of Quartz stalactite.

ST884 - Heulandite $ 300 (=~ £ 240) Rat's Nest Claim, Custer Co., Idaho, USA small cabinet - 6 x 5 x 4 cm Pink Heulandite on white Mordenite from the recent (approx. 20 year old) Rat's Nest claim in Idaho. This is a particularly aesthetic example from this find, which has produced oustanding (best ever?) North American Heulandite. Individual crystals reach 3.5cm and are undamaged. Ex. Lanny Ream.
ST942 - Chalcopyrite and Siderite $ 5000 (=~ £ 3998) Kaiwu Mine, Hezhang Co., Bijie, Guizhou, China cabinet - 15 x 10 x 4.5 cm Brassy, metallic Chalcopyrite crystals on translucent Siderite crystals from a limited find at the Kaiwu Mine in China. These were a one time find back in 2012 or 2013 and make stunning specimens due to the contrast in color and form between the Chalcopyrite and Siderite. The Chalcopyrite is bright and metallic with a slightly reddish irridescent surface coloration. The Siderite are translucent brown and lenticular in habit. There are also small white Dolomite crystals in areas. Fifteen cm! This is a large, museum sized specimen, which was unusual for the find, that is amazingly free of any damage (most were smaller and had some damage). This association hasn't been found since.
ST948 - Tourmaline with Topaz Stak Nala, Skardu, Pakistan small cabinet - 6 x 5 x 3.5 cm Two interconnected crystals of Topaz bisected by a single Tourmaline crystal with a touch of Albite at the base. Both of the Topaz crystals are glassy and translucent to transparent. The Tourmaline is Elbaite due to the presence of a thin green zone at the termination and provides a stark contrast between the two golden Topaz crystals. All the crystals are pristine and come together to form an aesthetic display piece. Comes mounted on a Lucite stand.
ST952 - Arsenopyrite $ 1800 (=~ £ 1439) Panasqueira Mines, Covilha, Castelo Branco, Portugal small cabinet - 7.5 x 4.8 x 4 cm Bold and dramatic bow-tie cluster of Arsenopyrite crystals from the Panasqueira Mines in Portugal. An exceptional example of a fairly common mineral, the cluster is complete all around and undamaged with bright, silvery metallic luster. Comes with a Lucite display stand. Ex. George Holloway specimen.
ST935 - Apophyllite with Stilbite $ 2500 (=~ £ 1999) Rahuri, Ahmadnagar Dist., Maharashtra, India small cabinet - 7 x 6 x 5 cm Glassy apple-green crystals of Apophyllite in an absurdly aesthetic bow-tie cluster. This specimen is the epitome of natural art. The cluster of Apophyllite crystals are perched dramatically atop peach colored Stilbite crystals. In the world of Apophyllite specimens, one in thousand is a bow-tie formation. Of those few, 99 percent have damage of some kind. Do the math, this is a special and rare specimen. Comes with a custom Lucite display stand.
ST939 - Volkovskite Boulby Mine, Loftus, N. Yorkshire, England cabinet - 10.5 x 8.5 x 5 cm Complete crystal group of the rare mineral Volkovskite from the Boulby Mine in England. This is one of only two known terminated crystal groups collected from a single find made deep in a section of the mine that extends out under the Altlantic ocean. The Volkovskite was found during normal mining operations for potash when the mine machinery stalled when it encountered a mass of the much harder Volkovskite. Because Volkovskite damages mine machinery, the area where it was found is now avoided and it is unclear if anymore will be recovered. This recent find of Volkovskite has set the world standard for the species and this specimen is one of the best. The specimen has crystallized surfaces all around - most were just cleavages (the cleavage structure can be seen on the bottom of this specimen, last photo).
