Beryl var. Emerald
stock #20.1-301-(LW1367)
Muzo Mine, Muzo, Municipio de Muzo
Boyacá, Colombia
1.2 x 1.1 x .8 CM (thumbnail)
price: $180


A single Emerald from the famed Muzo Mine, this is a gemmy hexagonal crystal with good green color. The crystal has some breakage mostly on the back and lower areas, some scuffs as well as a few inclusions. That said, it is a terminated crystal and a genuine transparent Emerald. Perfection in Emeralds is crazy rare and insanely expensive. This is a cute though not perfect thumbnail at 9.4 carats and is priced below the usual rate for this grade of rough.
Dolomite - blue crystals
stock #18.1-031
Muzo Mine, Muzo, Municipio de Muzo
Boyacá, Colombia
5.4 x 4.7 x 4.3 CM (cabinet)
price: $270


A cluster of sharp blue Dolomite crystals from the famed Emerald Mine at Muzo, Colombia. These crystals are over 1.5 cm across and have good luster, form and a color much like a nice Celestite. We obtained this piece in a lot we purchased from the miners in Colombia. They were initially certain they had made a big find of Euclase and were expecting to be very rich. After they learned the sad news that this was "only" Dolomite they were later happy to know that we valued the blue color far more than the normal white and bought everything! Blue Dolomite crystals are in general rare.
Gold - very rare wire form
stock #20.FC-091
Pinto River, Novita Municipality
Choco, Colombia
2.3 x .9 x .3 CM (thumbnail)
price: $2250


The rarest form f native Gold is this type of wire habit, these are only known from a handful of localities (I can only think of 4 or 5) and specimens are few and highly prized. This piece looks like a much more common Silver wire except for the bright golden patina. From an small but famed find at Choco in Colombia, this specimen comes from an older French collection. Presenting classic form, this slender wire with a hooking top or termination shows a little ropy texture on one side, the color is quite bright. One specimen from this find was the subject of recent research by Dr John Rakovan trying to determine the method by which these form. Careful study shows the exterior is very pure Gold but deeper inside there is a percentage of Silver. It is likely the Silver mixed with the Gold in rare instances may stimulate this type of form.
Gold - very rare wire form
stock #20-FC-092
Pinto River, Novita Municipality
Choco, Colombia
3 x 1. 2 x .9 CM (thumbnail)
price: $2950


A very fine and elegant Gold specimen. The rarest form for native Gold is the wire habit, these are only known from a handful of localities worldwide (I can only think of 4 or 5). Specimens are very few and highly prized. From some angles this piece looks like a dancer, this piece has two wires or rope-like growths from a flat nugget like base. From an small but famed find at Choco in Colombia decades ago, this specimen is from an old French collection. Classic form with twisting wires tapered to pointed ends. One specimen from this find was the subject of recent research by Dr John Rakovan trying to determine the method by which these rare wires form. So far, study shows the exterior is very pure Gold but deeper inside there is a percentage of Silver. It is likely the Silver mixed with the Gold in rare instances may stimulate this type of form.
SOLD Quartz -yellow tips w. Halloysite inclusions
stock #SOLD 19.1-866
Cabiche, Municipio de Quípama
Boyacá, Colombia
5 x 3.7 x 2.3 CM (small cabinet/ large miniature)
price: $0
Spring 2020

A choice and quite perfect example of the Yellow Tipped Quartz from the now famous find at Cabiche, Colombia. The Quartz crystals are gem clear with very bright yellow tips and a few wispy white inclusions near the terminations. The esthetics of the arrangement is very impressive in person and in exceptional condition as seen. This small find has been big news in the mineral world, this piece is far above average quality and about as fine a miniature as can be found.
SOLD Quartz with Epidote inclusions
stock #SOLD 20.1-104
Cisneros, Mun. de Buenaventura
Valle del Cauca, Colombia
5.4 x 5 x 3.6 CM (cabinet)
price: $0
Spring 2020

A stout Quartz crystal nested on and included by long crystals of dark green Epidote. The Quartz is a light milky green color but still transparent, the crystals of Epidote are clearly seen inside the Quartz. For ten years we have found occasional Quartz with Epidote from this region, but always badly damaged, still the potential looked exciting. This piece is from a new small find we were able to obtain in Colombia recently, these are by far the best specimens so far, this is a choice example. We hope for more in the future but that could be a long while!
Quartz - yellow tip - new find
stock #19.1-813
Cabiche, Municipio de Quípama
Boyacá, Colombia
4.4 x 4.2 x 2.9 CM (miniature)
price: $450


This amazing find of clear Quartz with bright yellow tips was big news in the mineral world recently. The find seems to be finished and these quickly became prized specimens. This piece is a choice example, with a strong display impact far bigger than the small size. In perfect condition the yellow tipped crystals are mixed with several clear, colorless prisms making a nice contrast. This does not have the muddy, brownish color that many have it is very bright and lively. The inclusions are still unconfirmed but the latest idea is Halloysite. No mater the included mineral the esthetic effect is impressive. Top bright luster and super clarity, a fine addition to any quartz suite or just for a spot of color on the shelf.
Fluorite - etched cube with
stock #18.1-540
Peñas Blancas, San Pablo de Borbur
Boyacá, Colombia
3.4 x 2.3 x 1.6 CM (small miniature/ large thumbnail (toenail))
price: $420
Dec 2018

A perfectly etched cubic Fluorite with the unique emerald green corners of Penas Blancas. This rare zoning has now been attributed to the same Chromium that colored the world class Emeralds found just a few hundred meters lower on this mountain. This is transparent and mostly colorless like an ice cube with complex crystallized. etched surfaces on all sides. There is no damage or chipping A very fine example that is choice, complete and shows the selective color in the corners perfectly.
