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.

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.

Hard to photograph the intensity of the green blue and orange colored face reflect
Very rare smoky quartz group with tapered shaped xls. Jack bought a small lot of these in a tiny one room shack in southern Bahia in 1978. There were small colorless beryls on some the quartzes. All were shaped in this tapered fashion.
A very rare occurence of a zeolite on smoky quartz. The piece on the other side is a very aesthetic group of extremely black, brilliant smoky quartz crystals, with curved faces.

Very unique and rare specimen of parallel growth Quartz crystals with a short scepter shaft. Deep hopper faces (indented crystal face development) From Brandberg Namibia, one of the premier specimen localities for fine Quartz. Click on image to enlarge and see other angles of view.
Crocodile Quartz with Smoky and Citrine colors. Smoky color is caused by long time exposure to gamma rays from the Sun. Some aluminum is contained in the Quartz as an impurity. The gamma rays cause the Aluminum to absorb frequencies of light to cause different color. (see color centers) We got this beauty at the 2019 Tucson show.
Shipping cost slightly more than $8, dep
