This is a beautiful cluster of intergrown pyrite and tetrahedrite.  When these two minerals form in the same location, they create interesting clusters where the sharp, cubic crystals of pyrite contrast with the more blocky, tetrahedral crystals of tetrahedrite. The contrast in their appearance is striking.

Pyrite is known for its ability to shield against negativity, boost confidence, and attract prosperity, while tetrahedrite promotes emotional healing, spiritual connection, and inner balance. Together, this cluster is believed to help manifest success, encourage personal growth, and maintain focus and clarity.

This top specimen is in very good condition. Would be a beautiful addition to any new or existing collection.

Pyrite from Bolivia is known for forming beautiful, well-shaped crystals, often appearing as sharp cubes, pyritohedrons (12-sided shapes), or even complex, stepped growth patterns. Bolivian pyrite tends to have a bright, brassy gold color with a good metallic luster, and it’s often found in association with other minerals like quartz or galena. 

Much of the pyrite from Bolivia comes from mining regions such as Potosí and Oruro, areas famous for their rich mineral deposits. While pyrite is common around the world, Bolivian specimens are valued for their attractive crystal habits, clean formations, and the quality of the material.

Pyrite is known as a stone of protection, abundance, and confidence.  It is believed to shield against negative energy and promote mental clarity and willpower.

This is a beautiful specimen of Pyrite from the Island of Elba in Italy. While pyrite is common around the world, this Italian specimens displays the typical pyritohedral form of the species.

Pyrite from Elba Island, Italy, is highly prized by collectors for its sharp, cubic, or pyritohedral crystals with a brilliant metallic luster. The most famous specimens come from the historical iron mines, particularly the Valle Giove mine and mines at Rio Marina. These pieces are often found in clusters, sometimes on a contrasting black hematite matrix, and are valued for their aesthetic quality and natural geometric perfection.

Cubic and crystallized pyrite matrix with Marmatite and Quartz crystal cluster.

Some of the more important Colorado localities for specimens of well-crystallized pyrite include mines at cli- max, Gilman, Leadville, Rico, Ouray, Telluride, Creede, Alicante, Alice, and State Bridge. Specimens from each of these localities often have distinctive crystal habits and mineral associations.  The Eagle mine is probably best known for its pyritohedral Pyrite specimens. This cluster is a good representative Eagle mine Pyrite showing typical striated pyritohedra with sharp, lustrous faces plus some Marmatite opaque black iron-rich crystals.

This is a fantastic crystallized pyrite core sample.   The specimen is rounded with brassy pyrite crystals.  A pyrite mine core sample is a cylindrical piece of rock, often several inches in diameter, extracted from the earth by a drilling rig to explore for pyrite deposits. These samples are used to physically examine the rock's geology, identify different mineral types like pyrite, and measure their abundance and distribution. Core samples are critical for determining the economic viability of a mine and are analyzed using methods such as visual inspection, microscopic examination, and chemical techniques.

This top specimen is in perfect condition. Would be a beautiful addition to any new or existing collection.
