This beautiful cluster of tetrahedrite with calcite, small terminated quartz crystals and small, but brilliant, crystallized pyrite. 

Tetrahedrite crystals are fascinating minerals known for their distinctive tetrahedral shape and shiny, metallic luster.  It typically forms in well-defined tetrahedral crystals, which can be grouped in clusters.  The color range includes shades of metallic gray, black, and sometimes reddish hues due to the presence of copper and other trace elements. Tetrahedrite is commonly found in hydrothermal veins and is often associated with other minerals such as quartz, galena, and sphalerite.

Tetrahedrite is believed to promote emotional healing and provide a protective shield against negativity. It is thought to enhance creativity and clarity, helping individuals connect with their inner selves.

This is an incredible green/yellow fluorapatite crystal from Cerro del Mercado (Iron Mountain) at Durango, Mexico. It is completely free of the matrix and has a relatively perfect termination. The specimen came from the Earl Calvert Collection.

At Cerro de Mercado numerous veins containing gemmy, lemon-yellow to greenish fluorapatite crystals cut through the hematite massif. These crystals have been collected for decades from the area's iron mines, but they have become much scarcer with recent mechanization of the mining operations.

The bright, lustrous apatite crystals form hexagonal shapes with off-center terminations. They are found in vugs, often associated with quartz and calcite. Most crystals are around an inch in length, though larger crystals up to about 4 inches long have been found.
