Zoisite (var: “Tanzanite”) (FOUR colors!) with Prehnite

Locality: Merelani Hills, Lelatema Mts, Arusha Region, Tanzania

Specimen Size: 5.2 x 2.3 x 2.0 cm (small cabinet)


When it comes to gem crystals, Tanzanite is one of the most well-known, highly sought after and valuable on the market. These crystals arguably may be the most popular non-pegmatite gem crystals extant. While good gem Zoisite crystals are fairly rare worldwide, the dazzling blue to purple variety, Tanzanite is only found in one area in the world. The material is becoming increasingly difficult to find these days, as the supply seems to be dwindling, and the best gem quality crystals are immediately destroyed as they are cut and polished into gemstones at the mine site. Zoisite is a pleochroic mineral meaning that it shows distinctly different colors when viewed along the “a”, “b”, and “c” axis, most often some shade of green or yellow. What makes Tanzanite so special is that the crystals will show an intense blue color along the “a” axis, and a strong purple color along the “b” axis, but the finest crystals exhibit the immensely eye-catching RED hue when view down the “c” axis. This crystal not only shows the classic blue, purple and red hues, but also a beautiful yellow-green color on the sides of crystals when viewed along the “a” axis, making this a rarely seen FOUR-color Tanzanite crystal! The colors seen in Tanzanite, along with its rarity are what make the material so valuable. Tanzanite is one of the great combinations of rarity and beauty in the mineral world, which often translates into some of the most prized material for dealers and collectors. In addition to the great colors exhibited in this crystal, it has excellent gemminess for the size, along with great luster, sharpness and a classic tapered termination. As if that wasn’t enough, for a final touch, there is a beautiful gemmy, yellow-green group of Prehnite crystals sitting right in the middle of the crystal. There are a few tiny rough spots to the piece, but it’s terribly difficult to find a completely undamaged, fully terminated gem Tanzanite crystal on the market. For the size, quality, color combination and overall appeal of the piece, it’s priced very fairly compared to many I have seen recently on the market. Last but not least, the piece comes with a custom made acrylic base for easy display. If you’re in the market for a classic Tanzanite crystal with a lot of a character, look no further.

Fluorite with Galena and Sphalerite

Locality: Naica Mine, Naica, Mun. de Saucillo, Chihuahua, Mexico

Specimen Size: 8.2 x 7.8 x 5.8 cm (small cabinet)
Largest Fluorite: 3.3 cm


ex.  Anton and Rudi Watzl


Several gorgeous, pale "water-green" color, GEM quality to translucent, sharp, cuboctahedral crystals of  Fluorite sitting atop a mound of crystallized black “Spinel”-law twinned Sphalerite and bright, metallic, silvery Galena. Some accenting white Calcite and minor golden Pyrite make for a colorful and very eye-catching display specimen. As you can tell from the photos, the piece can be displayed from many angles, as many of the Fluorites are completely undamaged. Great shape all the way around, and certainly worthwhile for any Fluorite collector or a collector of Mexican minerals. This piece is not from a recent find at the mine, but actually about 30 years ago (late 1970s). For the quality, associations, and overall aesthetics, it is a sweet small cabinet from this incredible mine.

Beryl (var: “Aquamarine”) on Albite

Locality: Shigar Valley, Skardu District, Baltistan, Northern Areas, Pakistan

Specimen Size: 9.5 x 8.0 x 5.3 cm (cabinet)
Aquamarine Crystal: 5.5 cm


It’s amazing to think that prior to Pakistan, it was nearly impossible to find a gem quality Aquamarine crystal on matrix from any locality. Places like Brazil and Russia were/are the some of the best known sources for Aquamarines, but they were almost never found on matrix. For me, this is a one-of-a-kind Aqua, and without question, a unique specimen. An unusually tapered crystal of crystal-blue color, GEM quality Aquamarine stands proudly on a somewhat feathery mound of white, bladed Albite (var: “Cleavelandite”). The Aqua has a wonderful presence that is complemented by its attractive modified hexagonal form with a gentle blending of sharp crystal faces, and subtle etching patterns along the prism. Due to the WATER-CLEAR transparency of the crystal, it was somewhat difficult to photograph, but you can literally look through the pinacoid and see all the way straight through to the matrix. The first and second order pyramidal modifications on the termination are a great touch to this already impressive and highly desirable cabinet sized display specimen. For the size, quality and showiness, it is competitively priced against many others on the market. This one certainly stands out amongst so many other Pakistani Aquas out there, and due to the pleasing aesthetic balance of the piece, it would show beautifully in a display case.

Topaz from Xanda mine, Virgem da Lapa, Jequitinhonha Valley, Minas Gerais, Brazil [./worldwidemix611/topbraz611a.JPG] Topaz from Xanda mine, Virgem da Lapa, Jequitinhonha Valley, Minas Gerais, Brazil [./worldwidemix611/topbraz611b.JPG] Topaz from Xanda mine, Virgem da Lapa, Jequitinhonha Valley, Minas Gerais, Brazil [./worldwidemix611/topbraz611c.JPG] Topaz from Xanda mine, Virgem da Lapa, Jequitinhonha Valley, Minas Gerais, Brazil [./worldwidemix611/topbraz611d.JPG]

Topaz

Locality: Xanda mine, Virgem da Lapa, Jequitinhonha Valley, Minas Gerais, Brazil

Specimen Size: 12.2 x 10.8 x 6.1 cm (cabinet)


The Xanda mine is one of the most prolific localities for blue Topaz in the world, and has produced some of the most impressive and memorable specimens with that distinctive preferential etching and larger sized crystals. This specimen is a rather large Topaz from any locality, not just Brazil, and is in amazingly good condition for the size. The crystal has rather smooth, sharp, well-formed faces with virtually no etching. In my experience, it is difficult to find full cabinet sized crystals that are so complete and essentially “textbook” in form. Overall, this gemmy/translucent, good blue color, sharp, lustrous crystal is a wonderful Topaz from this most classic of Topaz localities. There are only a handful of localities in the world that produce good blue Topaz crystals, and Brazil stands at the top of the list in terms of size, color and quality in my mind. A very fine natural blue Topaz specimen that is not priced at over 5 figures. Better color in person!

Dioptase (unusual material) from La Farola Mine, Cerro Pintado, Las Pintadas district, Tierra Amarilla, Copiapó Province, Atacama Region, Chile [./worldwidemix611/diopchile611a.JPG] Dioptase (unusual material) from La Farola Mine, Cerro Pintado, Las Pintadas district, Tierra Amarilla, Copiapó Province, Atacama Region, Chile [./worldwidemix611/diopchile611b.JPG] Dioptase (unusual material) from La Farola Mine, Cerro Pintado, Las Pintadas district, Tierra Amarilla, Copiapó Province, Atacama Region, Chile [./worldwidemix611/diopchile611c.JPG] Dioptase (unusual material) from La Farola Mine, Cerro Pintado, Las Pintadas district, Tierra Amarilla, Copiapó Province, Atacama Region, Chile [./worldwidemix611/diopchile611d.JPG]


No. DIOPCHILE611 - $ 3500.00 (=~ € 3137.40)

Dioptase (unusual material)

Locality: La Farola Mine, Cerro Pintado, Las Pintadas district, Tierra Amarilla, Copiapó Province, Atacama Region, Chile

Specimen Size: 11.6 x 8.8 x 4.3 cm (cabinet)


Certainly a deviation from what one would expect from a Dioptase specimen. Most people are familiar with rich emerald green trigonal crystals from localities such as Tsumeb, but this piece hosts a gorgeous velvety “carpet” of vibrant blue-green color acicular crystals forming radiating “balls” on contrasting host rock matrix. The color is virtually impossible to reproduce in the photos, as is often the case for Dioptase, and the piece looks even better in person. The various copper-producing regions in the north-central Chile have produced many interesting and unique specimens, with these Dioptases being among the best I have seen for this specific habit. Perhaps the most famous acicular Dioptase specimens in the world are those from the classic Mammoth-Saint Anthony Mine in Tiger, Arizona, and although I have only seen a few pieces from La Farola, they do compare favorably to the pieces from Tiger. If you’re a collector of copper minerals, Dioptase in general, or just colorful pieces from lesser known localities, be sure to pick this one up.
