Single crystalline floater block with parallel formation,
unique, red amethyst tips on the parallel scepters
Block at one time was a large quartz that fractured in a pocket and subsequent regrowth deposited numerous parallel scepters
Item: 3213 Locality: Four Peaks Mine, Maricopa Cnty, Arizona USA
Unusual elongated compound crystal with dramatic inclusions. Mined over 40 years ago. Doubly terminated.
It has some minor dings, as all this material was hauled in burlap bags. We are going through 3 tons of old mine production and this is one of the best so far.
Dramatic plate of parallel growth smoky quartz. Excellent example of crocodile quartz, or "jacare" in portuguese. It is healed on the back side and edges, as a "spall" or fractured surface area of a larger crystal in the pocket.
Item: 3830 Locality: Lavra do Ipe, Governador Valadares, Minas Gerais, Brazil
Very fine slightly smoky quartz crystal that twists at a constant angle on c axis. Termination is transformed into multiple parallel crystals. This is from Jack Lowell's quartz collection and was mined at a feldspar quarry in Gov. Valadares., probably around 1960. Has a few very, very minor dings at tip. photos of multiple termination available on request.
Item: 5105 Locality: Jaco Mine, Minas Gerais, Brazil
Quartz from this mine (owned by the Vasconcelos family in Valadares) is characterized by being floater healed sheets of colorless and sometimes smoky quartz that are terminated on all sides with brilliant complex face patterns. This rare specimen resembles a sailfish.
Item: 7968 Locality: Morro Velho Gold Mine, Minas Gerais, Brazil
Very rare curved Quartz crystals seemingly piercing each other. Beautiful freak of nature. From one of the deepest mines in Brazil, the Morro Veljho gold mine. Shipping cost will vary by location. Weight 6 lbs.
Decor specimen, this weighs about 7 lbs. and consists of giant green fluorite crystals covered with drusy Quartz.
Can be put over a small light so it would glow green in the dark. (Inquire about having us fix it into a beautiful artwork for your living room.) Cost of a light and base would be $35 extra.
Item: 7965 Locality: Morro Velho Mine, Minas Gerais, Brazil
From the Morro Velho Gold Mine in Brazil, a beautiful group of quartz with Dolomite, some Siderite, and minor sulphides. Very dramatic specimen. Better than most museum specimens for Quartz, very fine. .
Item: 7992 Locality: Morro Velho Gold mine, Minas Gerais, Brazil
Really complex piece with flawless gemmy Quartz crystals in scattered group on matrix of Dolomite, minor Siderite and minor Pyrrhotite crystals. Very aesthetic, from the deepest gold mine in South America.
Beautiful group of transparent quartz with intergrowth of microcline at base. Excellent pegmatite specimen from the king country of pegmatite minerals. Weight is about 5 lbs. so nominal shipping surcharge will apply
Very rare specimen of a Quartz crystal cloaked in crystallized Pyrite with only a portion of the the Quartz revealed. Formerly in the Victor Yount collection, traded to Jack Lowell , and then later sold to Dave Daniel. A very fine specimen.
Perfect doubly terminated Quartz with smaller one, with an interior like a micro circus. Turn it around and sideways and the trapped solid Hydrocarbon inclusions float in liquid and gas bubbles float upwards inside the bubbles. This is a carnival inside a crystal.
An extremely rare Amethyst specimen, purchased in Brazil by Jack Lowell in 1973, on his first trip to Brazil, from the famous jewelry designer Haroldo Burle Marx. It began growth as a colorless enlongated prism, and at a later time formed a deep reddish purple tip with several smaller Amethyst crystals of the same color. It came from a pegmatite, which is a rare geologic origin for
Intricate growth of brilliant quartz crystals and one Amethyst crystal with small calcite crystals and two unknown minerals, one a copper mineral, the other a dark finely crystallized mineral. For an additional
$35 we will have it analyzed. This piece is very aesthetic with several display angles.
Very rare transparent quartz crystals with irridescent orange rhombonedral faces with green accents. difficult to photograph, but most crystals show the effect when rotated in light source. We will include a copy of the 1950 scientific paper on this discovery by Sir CV Raman.
Of all the Rainbow Quartz we have received, this piece has the best "lights" of all. Many crystals at once show green, orange, or blue neon faces. Very rare specimen. The optical phenomena (Irridescent faces in Quartz) was first described by CV Raman in 1950. We can give you a copy of the article in the Indian Academy of Sciences.
Stalactite of AAA Rainbow Quartz, with entire faces of electric blue, green, and orange, depending on light source. Very strong and visible effect of Adularescence that is difficult to photograph, most Rainbow Quartz is like this. It is much better in person. This is a top quality specimen and will amaze you and everyone else with it's electric colors.
