Quartz included by Epidote
stock #20.1-880
Cisneros, Mun. de Buenaventura
Valle del Cauca, Colombia
4.1 x 3.3 x 2.1 (miniature)
price: $150
new year 2021

A light greenish Quartz that is slightly milky is surrounded by and included with slender Epidote crystals. From a remote locality in the Gold mining areas of the Cauca Valley of Colombia, these greenish Quartz and Epidote have trickled out for several years, never many pieces and usually badly damaged. This is from a small lot we obtained in Colombia in 2018 and is far better than usual. The front or display side offers a large window into the Quartz where the Epidote are like a forest or garden scene. The backside has a clean geometric contact and the condition is overall very good, strong magnification does show some very tiny bruises that are not visible by naked eye, for one of these remarkable crystals this as close to perfect as we have seen. A very different and attractive small Quartz.

Dolomite cast with Calcite
stock #16.1-308
Otjikoto Region, Namibia
4.3 x 3.4 x 2.2 CM (miniature)
price: $120
new year 2021

One of the many odd but amazing things found over the years in Tsumeb were hollow Dolomite casts. These are replacements or encrustations of earlier minerals which have since disappeared. Sometimes the casts have then been overgrown with other minerals as well. The forms are quite diverse and entire collections have been made of the many shapes, colors and associations. This miniature cast is a pale green color and is overgrown with gem clear, colorless Calcite rhombs. The walls are typically thin and the whole specimen is a delicate hollow structure. Looks great from any angle, an attractive example of a mineral oddity.

stock #14.1-380
Minas Gerais, Brazil
4.6 x 3.5 x 1.4 CM (miniature)
price: $300
new year 2021

A pair of fine, sharp and lustrous crystals of Epidote from Capelinha in Brazil. Most of the Epidote we see from Brazil is a more fibrous habit, this prismatic specimen is the best formed I have ever seen. Textbook perfect crystals with well-defined terminations and on the backside a few clusters of small Quartz crystals. Overall in excellent condition as seen, the faces are either well-striated or perfectly flat, mirror-like and brilliantly lustrous. The sharpness and quality of this could easily be confused with a fine Alaskan Epidote.

SOLD Fluorite on Quartz
stock #SOLD AX-14-346
Orange River, Namakwa
Northern Cape Province, South Africa
3 x 2.8 x 2 CM (thumbnail)
price: $0
new year 2021

A super esthetic thumbnail from the Orange River area on the border of Namibia and South Africa. Orange River Quartz is well-known for the orange to red coloring of the crystals caused by Hematite inclusions. This piece has a light red zoning on transparent Quartz crystals that are the hosts for small zoned cubes of Fluorite. The Fluorites are very sharp, deep purple in the core with transparent zoning outside including a light yellow edge area. In fine condition overall, there is some very tiny chipping (under 0.2 mm) found with magnification, not visible to my unaided eye. This area has unusual mineralization which is unlike any other area I know of, this piece from a small unique find in 2017. This is a choice thumbnail from anyplace with nice color contrast.

SOLD Epidote on Pericline (Albite)
stock #SOLD 20.1-879
Acushnet Quarry (Warren Bros.) Acushnet, Bristol County
Massachusetts, United States
5.2 x 3.73.2 CM (small cabinet/ large miniature)
price: $0
new year 2021

An unusual USA find from Alpine Clefts that were found in the Acushnet Quarry on Massachusetts. These clefts were the source of some fine Adularia, Apatite and Epidote, a rare context on this continent. The Pericline is formed in distinct pink and white zoned crystals that are the matrix for a jumble of jackstraw prisms of Epidote. The luster and color of the Epidote is unusually good for this find and the crystals are transparent, up to 1.4 CM though most are smaller. In excellent condition, an attractive alpine style specimen not often available and quite rare from this continent.

SOLD Topaz - Imperial with rare hematite zone
stock #SOLD 17.1-176
Antonio Pereira Mine, Ouro Preto
Minas Gerais, Brazil
6.3 x 1 x .7 CM (cabinet)
price: $0
new year 2021

A long, slender perfectly terminated crystal of Imperial Topaz from the famed Ouro Preto locale. This has the rare zoned inclusion of Hematite inside the lower portions of the crystal. In person the top section is bright, gemmy transparent and very glassy. The lower section is also gemmy in some spots and on the edges, but the dark inclusions are opaque in the center. In exceptional, undamaged condition, this color zoning is rare and this piece is an excellent example. Imperial Topaz is unique to this area, the form and color is classic. While inclusions are not that uncommon from here, these "bi-color" crystals are remarkable, rare and impressive.

Fluorite - zoned with hoppered faces
stock #15.1-028
Cave-in-Rock, Hardin County
Illinois, United States
5.7 x 4.8 x 4 CM (cabinet)
price: $440
new year 2021

A classic purple, blue, yellow Fluorite with well-defined sharp cubes in a cluster. Some of the square faces of the cubes have distinct geometric voids or hoppers with complex cubic forms. This Fluorite looks dark without some backlighting (see the second photo) but the effect of that backlight brings out excellent color zoning, The cubes are complete, glassy and in very good condition, some faces are perfectly flat as well. From the Cave in Rock area of Southern Illinois, this is a very pretty yet affordable dark Fluorite with great colors hiding inside.

Fluorite on Schorl
stock #AX-14-159
Erongo Mountain, Karibib
Erongo Region, Namibia
6.8 x 5.3 x 4.6 CM (cabinet)
price: $790
new year 2021

Colorful zoned Fluorite crystals are perched on a jumble of lustrous Schorl crystals from Erongo. Close exam of the Fluorites shows they are also included by dark tourmalines some of which have areas of transparency. The Fluorites have some spots of deep purple set in a light blue background. These crystals are somewhat etched and show some spinel twinning as well. The Schorl crystals are in two habits some with the fibrous habit faces and others with prismatic forms. All are quite lustrous and with two different termination types. Overall very esthetic and striking specimen from a find in 2018. The pegmatites of Erongo have given up some remarkable pockets over the years many of which were unique having unusual habits and forms not seen in any other. We have not seen any more recent finds of this style.
