 Have a look at some Elmwood specimens I've got for sale right now by clicking on this link


World class specimen, 33.5 X 25 cm, with a 15 cm calcite twin and numerous smaller calcites, perfect, no dings or chips. The calcites actually attach two pieces of limestone matrix, showing the geological history of the formation. The specimen comes from a breccia pocket wherein the original limestone collapsed, likely during an earthquake. Later, calcite crystals were deposited out of solutions that filled the collapsed but still open-spaced pockets. These calcite crystals are the most perfect champagne color, not too light, not too dark and absolutely flawless. These extremely gemmy crystals are rare.

Sit back 4-5 feet from your monitor. Cross your eyes (look at your finger 1 foot in front of your eyes if you can't cross your eyes on purpose) until the X's overlap perfectly. Get it so there are three images. The middle one will be in stunning "3-D."

  A stunning, gemmy Elmwood, Tennesee calcite, 16.5 cm long with perfect terminations. This is the most rare of the Elmwood calcite, with extreme clarity and deep orange/golden color. Look at the light coming out of it onto my hand! Also notice you can see my fingers clearly through the crystal. The main crystal is doubley terminated. On the left a second termination formed as a twin on the other side of the crystal. This is almost a floater, with only a tiny area on the bottom where it was attached to matrix.

The base is crumpled aluminum foil sprayed with flat black paint. Makes an interesting base for minerals.

An 8 cm gem Elmwood calcite, looks like frozen apple jelly.

Summit, New Jersey

A very large hexagonal calcite growing out of a sphalerite matrix, this is simply a spectacular specimen. The crystal is 15.5 cm wide, rises 7 cm above the sphalerite matrix, and is 4-5 cm thick. The sphalerite matrix is about 5 cm thick. The color in the photo is very accurate, with a subtle pink and light preferential coating of some surfaces with a light tan.

2nd Sovietskiy Mine

This is a very large, 15 cm, doubly terminated calcite that grew in a hexagonal prism. The "nailhead" (technically "pinacoidal") terminations are beautifully striated and flawless. What makes this specimen even more extraordinary is the two twins that grew from opposite faces of the main crystal. Their axes lie perfectly along the cleavage planes of the main crystal and their a-axes are rotated 120 degrees with respect to each other.  The First Sovietsky mine was opened in 1934 and closed in 1965. The eariliest generation of calcite was platy, the "angel wing" form; that can be seen on the back of this specimen. The prisms terminated by pinacoids was the later generation that grew over the "paper spar." The calcite occurred in giant veins at the junction of limestone with the orebodies of zinc, lead and silver (REF: Calcite, extraLapis English #4, 2003).

"Angel wing" calcite

Specimen  approx. 25 X 25 cm

Obtained at a rock show 30 years ago from someone who claimed it came from a then-closed mine in west Texas. Anyone knowing the origin of this type of specimen...turns out its from near a village called San Antonio in Durango state, Mexico:

THANKS to Charles Creekmur for identifying the locale of this specimen. He wrote "The present operating mines are located 3.2 km north and south of the original La Amparo.  The new mines are extensions of the older operations and still carry the same mine name.  The calcite is found in faults and fissures in the rhyolitic rock.  The crystals occur as large plates or "boxworks" called "angelwing" calcite.  The mine is operated for the fine grade of optical calcite found at the base of the angelwing crystals.  These crystals are broken off to expose the small zone of optical beneath.  This location has been listed as Rodeo, but the closest village is the small pueblo of San Antonio, state of Durango."
