A choice Sri-Lankan specimen. Crystals of elongated Zircons that are reddish purple in color are up to 2.6 CM on a complex matrix. The specimen includes Sphene crystals to 3.5 CM. Despite some small broken crystals and contacting the piece still presents very well. The luster is a slightly "melted" look but still glassy and bright. Ex collection of Chris Amo, this is a very well formed example of the elongated habit of these Zircons.
An older very fine Fluorite that is a pure mass of oriented crystals all of which are modified cubo-octahedral or dodecahedrons. In fine condition, the display sides are choice and undamaged only the backside is contacted. The larger crystals are fully transparent and have very good luster. Dispalys well from several angles, this style and habit has not been available recently except from older stock (as this is). A modern Chinese classic.
An eye-catching complex cluster of very sharp crystal forms that show clearly the original shape of the Azurite crystals that were altered to Malachite and are now nearly all Chrysocolla. A few of the smaller crystals have broken section that show the core of unaltered Malachite. Other crystals are now hollow as well, reaching up to 3.2 CM long. Overall this is a delicate specimen that is very 3 dimensional and a choice cast form . One of the mineralogical discoveries that made big news about 2 years ago, these are now quite scarce on the market.
A main gem clear Tremolite prismatic crystal sticks straight up from a complex mix of Tremolite, Diopside and Calcite crystals. From the classic locality of Pierrepont in St Lawrence County, New York, this was found a few decades ago by the late Skylar Alverson, a legendary collector in the area. In excellent condition the main crystal is well terminated and has a pleasing blue-green color. The matrix is sawn on the back and bottom to allow it to be collected intact, the cut marks are not visible on display. A very fine example of the specie and is typical of a choice specimen from the famed Skarn gash veins of the region.
Elbaite- gem crystal
Pederniera Claim, Sao Jose da Safira, Doce Valley
4.2 x 1.1 x .8 CM (miniature)
Bright green to blueish glassy luster tourmaline crystal in excellent condition. Nearly all gem grade, this weighs 6.5 Grams, and has only a few minor internal veils. Excellent example of this style from the great Pederneira Mine, there are no chips or flaws on the entire prism or termination, althouh this is inclomplete on the bottom end where it came from the matrix. That is not visible when displayed.
Elbaite on and in tabular Quartz
Cruzeiro Mine, Sao Jose de Safira
3.3 x 2.6 x 1.2 CM (small miniature/ large thumbnail (toenail))
A dark green to bluish pair of Elbaite crystals are laying on the flat face face of this tabular Quartz crystal. Very unusual and presenting an unique esthetic. The Tourmalines look nearly black in some light but with strong backlight the color and translucence is more distinct. The larger Tourmaline is contacted on one end but well terminated on the other, the smaller is doubly terminated. Aside from minor edge chipping the specimen is in fine shape. The Quartz is especially clear, completely transparent, doubly terminated and very glassy. Best appreciated in person.
A bizzare, unique, rare but attractive Aquamarine. From the Erongo Mountains, (Hohenstien Massif) this is a complete, doubly terminated crystal. The flat termination is typical although in this case the corners have modified faces. The real interest is the other termination that is a series of hexagonal steps that are perfectly centered like a stairway or a turret. The 4 main steps or platforms are very flat and some edges have a little etching, the whole is therefore a reversed scepter. Some minor contacting/chipping is noted but overall the condition is excellent. A good display piece but especially a great addition for a suite of Namibian/ Erongo minerals, Beryls or exotic crystal forms.
Calcite -Gem clear with phantom
Leiping Mine, Leiping, GuiyangCo., Chenzhou Prefecture
4.1 x 3.6 x 2.5 CM (miniature)
Bright luster, exceptional clarity and sharp form, a choice miniature from the now famous Leiping mine. In perfect, undamaged condition, this mine is famous for these superb Calcites and the bright Hematite phantoms. Very few have been available in recent years. Similar in form and habit to the classic English Calcites from the Iron fields in Egremont, these are far less expensive yet just as attractive.
