Tourmaline (35 year old specimen) from Cruzeiro Mine, Sao Jose da Safira, Minas Gerais, Brazil [./gemcrystals510/tourmbr510a.JPG] Tourmaline (35 year old specimen) from Cruzeiro Mine, Sao Jose da Safira, Minas Gerais, Brazil [./gemcrystals510/tourmbr510b.JPG] Tourmaline (35 year old specimen) from Cruzeiro Mine, Sao Jose da Safira, Minas Gerais, Brazil [./gemcrystals510/tourmbr510c.JPG] Tourmaline (35 year old specimen) from Cruzeiro Mine, Sao Jose da Safira, Minas Gerais, Brazil [./gemcrystals510/tourmbr510d.JPG]


No. TOURMBR510 - $ 1500.00

Tourmaline (35 year old specimen)

Locality: Cruzeiro Mine, Sao Jose da Safira, Minas Gerais, Brazil

Specimen Size: 5.3 x 1.7 x 1.6 cm (small cabinet)


ex.  Richard A. Kosnar


A wonderful gem quality Tourmaline crystal from the famous Cruzeiro Mine. This specimen was purchased by my father in Brazil in 1974, and remained in our collections for over 35 years. The piece is completely unrepaired and shows a beautiful bicolor appearance with a WATER-CLEAR, vibrant grass green to slightly blue-green hue at the termination and upper portion of the crystal, which grades into a lovely gemmy pink color, that is actually surrounded by a thin green “rind” creating the well known and desirable “Watermelon Tourmaline” effect. To find Tourmalines with such richly colored, TRANSPARENT sections in the crystals is quite rare, and this is not a thin “pencil” crystal, as it has a bit of girth to it. The modifying pyramidal faces surrounding the termination give the piece a lot of character, and it stands out from many others I have seen from this mine. Overall the piece is damage free, save the bottom of the crystal where it detached from the pocket wall. A great older Brazilian Tourmaline crystal, the likes of which are not commonly seen on today’s market.

Beryl (variety: “Aquamarine”)

Locality: Jaquetô, Bahia, Brazil

Specimen Size: 4.2 x 1.0 x 0.8 cm (miniature)


ex.  Richard A. Kosnar


A nearly 100% gem quality, light blue color, prismatic, slightly etched crystal of Aquamarine. The piece was mined about 30 years ago, and comes from the collection of Richard Kosnar, who had a strong presence in Brazil bringing back a large quantity of pegmatite minerals in the 1970s. The crystal has a few slight “tube”-like inclusions near the termination, and the geometric etching patterns along the prism faces make for a great touch.

No. AMETBOL510 - $ 700.00

Quartz (variety: “Ametrine”)

Locality: Anahi (Anay), Santa Cruz, Bolivia

Specimen Size: 8.5 x 5.2 x 2.9 cm (small cabinet)


Ametrine is a unique, naturally occurring purple and yellow bi-color variety of Quartz that is formed by "Brazil Law Twinning" where two separate individually colored crystals are intergrown to form an alternating "radiation" pattern of purple and yellow triangles when viewed down the c axis. Gem cutters are able to orient the two colors to create the famous bicolor gemstones. Here we have a natural, nearly 100% gem quality, hydrothermally etched, bi-color purple and yellow crystal of Ametrine. Note the rarely seen “c” {0001} pinacoid face at the top of the crystal, which is virtually unheard of when it comes to Quartz!

Beryl (variety: “Aquamarine”) from Sawtooth Mountains, Idaho [./gemcrystals510/aquaid5101a.JPG] Beryl (variety: “Aquamarine”) from Sawtooth Mountains, Idaho [./gemcrystals510/aquaid5101b.JPG] Beryl (variety: “Aquamarine”) from Sawtooth Mountains, Idaho [./gemcrystals510/aquaid5101c.JPG]


No. AQUAID5101 - $ 400.00

Beryl (variety: “Aquamarine”)

Locality: Sawtooth Mountains, Idaho

Specimen Size: 2.6 x 1.0 x 0.9 cm (thumbnail)


This Aquamarine specimen was mined by Richard Kosnar in the late 1970's and his diggings produced some of the finest color, unheated Aquamarine in the world. Most of these crystals are not gem quality, but this crystal is approximately 90% gem clarity, which is very good for the material. This crystal is a fine, sharp, GEM/gemmy, slightly hydrothermally etched, rich blue color prism of Aquamarine from one of the more obscure localities for the material. The crystal has an interesting zone near the termination that looks like a snow-capped peak. One simply does not see these beauties offered very often on the market anymore. It is definitely one of the best blue color crystals of this material that I've seen from Idaho. A great North American gem crystal classic!

No. TOURMPAK510 - $ 500.00

Tourmaline

Locality: Gochalay, near Shengus, Northern Areas, Pakistan

Specimen Size: 3.6 x 1.2 x 0.8 cm (miniature)


Tourmalines are certainly among the most popular species for collectors, and no matter how many one encounters, a good one will always draw attention. This beautiful crystal has a striking color combination with a gemmy colorless ("Achroite") “cap” which gives way to a stunning teal/blue color that mixes into an inky purple color (almost black) at the base. For a smaller Tourmaline crystal, this one is unique, eye-catching and just plain pretty. To the best of my knowledge, the find of these crystals was very limited and I have not seen any of them available from the Pakistani dealers for quite a while. An unusually colored and attractive gem crystal.

No. RUBYAFGH510 - SOLD

Corundum (variety: “Ruby”)

Locality: Jagdalak (Jagdalek) Ruby Mine, Kunar Province, Afghanistan

Specimen Size: 5.2 x 4.1 x 2.8 cm (thumbnail)
Ruby Crystal: 9 mm across


The Rubies from Jagdalak are among some of the most well known, classic and superbly crystallized matrix Ruby specimens around. This specimen features a remarkably sharp, very well formed, lustrous, "pigeon-blood" color crystal with great form on a mixed marble/Mica/Pyrite matrix. The crystal is not at all opaque as the majority of these specimens tend to be, and as you can see from the photos, the color just glows when the crystal is backlit. A beautiful display specimen that could probably be trimmed down to a knockout thumbnail.

Specimen Size: 4.1 x 3.0 x 2.8 cm (miniature)
Spinel Crystal: 1.0 cm across


ex.  Richard A. Kosnar


It has been next to impossible to obtain fine quality Spinel specimens from Burma these days it seems. Matrix specimens of Spinel are uncommon, and to find gem quality crystals on matrix is extremely difficult. This piece hosts a classic Burmese "Ruby Spinel" crystal with very sharp, defined, lustrous, octahedral faces and a gemmy rich red color. The crystal sits atop a matrix of massive white Calcite as is typical for this locality. The piece is very showy and extremely aesthetic for the material, and certainly not easily replaced in this market. This piece was mined around 2000, and is one of the finest Spinels from the collection of my father, Richard A. Kosnar. The best of these specimens are simply the finest in the world for what they are. This is an example of a non-pegmatite gem mineral for which many collectors probably do not have a good specimen in their collections.

Spinel (“Ruby Spinel”) (“Star of David” Twin)

Locality: Mogok, Sagaing District, Mandalay Division, Burma

Specimen Size: 5.5 x 5.0 x 2.0 mm (thumbnail)


Spinels are typically found as single isolated octahedral crystals, but they have an actual crystal twinning habit (“Spinel-Law”) named after them. This “floater” twinned crystal is a classic Burmese "Ruby Spinel" with relatively sharp, lustrous faces, but the most interesting aspect of the piece is the fact that it is a rarely seen “Star of David” twin with a vibrant pink-red interior color. An great quality twinned crystal for the species. This piece was mined around 2003. The best of these specimens are simply the finest in the world for what they are. This is an example of a non-pegmatite gem mineral for which many collectors probably do not have a good specimen in their collections.

This GEM quality light blue, very sharp, rather lustrous, doubly-terminated, striated, "floater", hexagonal Sapphire TWINNED crystal is a marvelous example of how fine the quality of these crystals can get. The crystal is pristine on all sides and absolutely water-clear in about 85% of the specimen. For the quality, this would make a spectacular addition to any thumbnail suite, or a small gem crystal collection.

A fantastic old time, cabinet size Afghani Tourmaline "log" with vivid pink and green color zones. The crystal is exceptionally gemmy with very glassy faces and pristine pyramidal termination on the top plus a re-healed termination on the bottom. My father purchased this specimen in the early 1980's when Afghanistan was just starting to produce these crystals, and it has truly stood the test of time. It is far superior in quality to the vast majority of contemporary Tourmalines from Afghanistan that I have seen in recent years which seem to have more of a pastel hue and sometimes a grey overtone. An impressive and richly colored Tourmaline specimen from what is one of the premier countries in the world for the material. The piece comes with a custom-made acrylic base for easy display!
