Quartz Crystals exhibiting elestial growth. Elestial crystals have a distinctive skeletal or etched appearance, characterized by intricate growth patterns and layered formations. These skeletal growth patterns are caused by unstable conditions during their formation. Specimens showing this layered growth are often referred to alligator quartz. Specimen also shows hematite coating. Red Feather Lakes. Larimer Co., Colo.
Don't they look pretty? These caught my eye when I went in to turn the lights off in my treatment room last night, they really sparkled in the light from the lamp.
Gyrolite on Quartz. Gyrolite is a hydrated calcium silicate hydroxide. Malad Quarry. Mumbai District. Mumbai, Mahrashtra, India
Locality: Green Monster Claim, Prince of Wales Island, Alaska
Size: Specimen is 1.4 inches tall on right side from base to the tip of the quartz crystal.
This portion of the Highway 1 Kamloops to Alberta program involves replacing the two-lane bridge crossing at Quartz Creek, 40 km west of Golden, with a new four-lane bridge, access improvements to forest service roads and widening 4.4 km of two-lane highway to four lanes.

An amazing litle world made of billions of egg shaped quartz grains. This is the combined effect of erosion, river and sea transport. Is Aruttas beach, Sinis peninsula, Sardinia.
Synthetic Quartz. The mineral is silicon dioxide. These man-made crystals were grown under labratory conditions. (Collection of the Colorado School of Mines Geology Museum. Golden, Colo.)
Locality: Baia Sprie mine (Felsőbánya mine), Baia Sprie (Felsőbánya), Maramureș, Romania

The most abundant elements making up the crust of the Earth are oxygen and silicon. They are found in many minerals but are solely bonded together in Quartz. It is the second most abundant mineral in the crust after Feldspar. This is a shot of a crystal of Quartz. The arrangement of atoms in the mineral give it a unique crystal shape.

SC2-3109
Part of a massive geode in the American Museum of Natural History, New York City. It was nine feet tall and weighed as much as four rhinos... though I have no idea why rhinos is now a unit for measuring weight. I also think it kinda looks like the galactic core.
I collected this 15 mm doubly-terminated quartz crystal at the Miller Mountain Mine, Garland County, Arkansas in 2007.
Normal White Light, Backlit with White Light, Illuminated with UVa
Locality: Xianghualing Mine Linwu Co. Chenzhou, Hunan, China
Size: Specimen is 5.14 inches wide
SC2: JP25
I collected this 13 mm crystal at the Stoddard Mine in Westmoreland, New Hampshire just this past weekend (April 29, 2006), on a Boston Mineral Club field trip. The ground was literally littered with quartz crystals and fluorite. The yellow is due to iron oxide staining, easily removed but I like the color.
