Dogtooth Calcite is a variety of Calcite that forms as multiple scalenohedral crystals. Dogtooth Calcite
is often referred to as Dog-toothed Spar. (Spar is a general term for transparent to translucent, generally
light-colored and vitreous crystalline minerals.) Dogtooth Calcite is an unusual variety of calcite and is
named "Dogtooth" because the stone itself looks like a large collection of dogs teeth. It has some
standard colorings from clear through golden, white, grey, tan, brown and purple to name a few, but also
is found some rarer shades.
Dogtooth Calcite is often found in caves as a speleothem growing out of limestone. These caves often
have standing water that is seasonal or undisturbed for many years to allow these unique formations to
grow. Dogtooth calcite crystals are not limited to caves, but can grow in any open space including veins,
fractures, and geodes.
The sharply tooth-shaped crystals typically consist of acute scalenohedrons, twelve triangular crystal
faces that ideally form scalene triangles. (In a scalene triangle, all sides and all angles are unequal. An
example is a right triangle, but scalene triangles are not always right triangles.) However, modification of
these faces is common, and individual crystal faces may have many more than three edges.

| Item # DTC11101145 Rare 7.94 lb Tower of Dogtooth Star Calcite Balls with Selenite $349.00 |
| Rare 7.94 lb Tower of Dogtooth Star Calcite Balls with Selenite This specimen is a very rare find! We procured it from a supplier who personally goes to the mines in Chihuahua Mexico daily and hand picks only the best and rarest finds from the mines. He kept this one packed away for a few years because he had never seen another one like this. We finally got this beauty and have listed it for your pleasure. Excellent Free Standing Display Piece! This piece is about 4.8 inches (12.2cm) in diameter and stands about 6.5 inches (16.5cm) tall. This unique piece has diametrical growth color variations from the interior (top right photo)and exterior macroscopic properties much like star quartz balls or spirit quartz type look. Research on the crystal formations left us at a loss for a definitive name for the pattern so we elect to call it "Dogtooth Star Calcite Balls" The formation has many very sharp dogtooth calcite crystals in the star ball formations. There is a sprinkling of white selenite that is similar to the "Calcite of the Stars" listed above. There is one star ball that was broken during the removal of this specimen from the mine. The last two photos show this damage. Inspection of this piece shows no other damage outside normal removal breakaway. We debated about even selling this piece...don't know if we will ever see another like it...but...we can't keep everything. The price?....Set by us....it may be worth many times that amount. It's hard to set value on "One of a Kind" specimens...oh yes, when you handle this piece please wear leather gloves...the dogtooth "really bites you" on this one...Sharp Points! |
