Beauty of Art and Images for you
The beauty of nature’s images
BEAUTY OF THE ROCKS
I was looking for you – my dear friends – images that bring together the beauty of natural rocks, the charm of colors, and the beauty of photography.
I hope you find a great pleasure
Locality: Winza, Mpapwa, Mpapwa (Mpwampwa) District, Dodoma region, Tanzania. Size: thumbnail, 2.8 x 2.0 x 2.0 cm. This is a killer thumbnail specimen. A bit of matrix is host for 2 crystals of lustrous and translucent, cherry red ruby with exquisite micro-details on the faces and sharp bevelled edges. The larger one, exhibiting superb crystal form, measures 1.5 cm across. These ruby crystals are totally unique in form, and combined with color and gemminess make for a dramatic matrix presentation that is unlike rubies from any other locality in the world.
Locality: Tongren Mine, Wanshan District, Tongren Prefecture, Guizhou Province, China. A beautiful specimen of Cinnabar featuring dozens of blood red, gemmy prismatic crystals on Dolomite on matrix. Very pretty piece with good color, and they arent as common as they once were. This habit, of sharp gemmy crystals, is actually more rare than the twinned form. 7.2 x 4.6 x 2.0cm.
Locality: Chihuahua, Mexico. This is a SUBSTANTIAL specimen of gem fire opal, a full centimeter thick and over 3 cm across, worth quite a bit as rough for jewelry, but a superb specimen for a collector in and of itself. The color is the best fiery orange, and the opal is gem-clear. ex Zinn Collection 6.3 x 5.9 x 3.3 cm
Locality: Kolwezi, Western area, Katanga Copper Crescent, Katanga (Shaba), Democratic Republic of Congo (Zaïre).Size: 10.3 x 9.6 x 2.5 cm. On the edge, you can see the bands running through the malachite. There is a nice balance here of the green banded malachite and deep turquoise-blue chrysocolla – both copper minerals, from the prolific copper mining district in Kolwezi Province. This piece has pretty bull’s-eyes surrounded by the blue, which is very desirable in these specimens.
Locality: Aguascalientes, Mexico. Size: 3.9 x 2.9 x 1.7 cm. This is a polished specimen of « fire agate » that is very rare. It plays with light the way opal does, from fiery reds to neon green. This is a sizeable 20-gram specimen that is only about 10% matrix.
Calcite (Var.: Cobaltoan Calcite)
Locality: Bou Azzer District, Tazenakht, Ouarzazate Province, Souss-Massa-Draâ Region, Morocco . Admittedly a bit “matrixy” and not as bright pink, but this one has the largest crystals of the whole batch – to 1.5 cm. They are a differrent habit with modified scalenohedra and a slight matte texture to the surfaces. 6 x 4.5 x 4.5 cm

Valzergues Mine, Aveyron, Midi-Pyrénées France – (39x20cm)

Is a brittle metal with a white, silver-pink hue, often occurring in its native form, with an iridescent oxide tarnish showing many colors from yellow to blue. The spiral, stair-stepped structure of bismuth crystals is the result of a higher growth rate around the outside edges than on the inside edges. The variations in the thickness of the oxide layer that forms on the surface of the crystal causes different wavelengths of light to interfere upon reflection, thus displaying a rainbow of colors [Wikipedia]
