This is a beautiful, fully terminated thumbnail sized Quartz Point. 

Quartz crystals are among the most abundant and well-known minerals on Earth. Quartz belongs to the hexagonal crystal system. It typically forms six-sided prismatic crystals with a pointed termination. Its crystals can be colorless or exhibit a wide range of colors. The color variations are often due to the presence of impurities or trace elements during the crystal's formation. Quartz is transparent to translucent. 

This specimen would be a beautiful addition to any new or existing collection.

Quartz from this quarry is known as the best of its kind. These specimens have a unique brightness and surface sparkle preferred by collectors around the world.  The crystals are intergrown with many others in jackstraw groups which are not attached to matrix: giving you an unlikely-looking floater specimen. The specimen is in very good condition.

Pseudomorphs are mineral specimens that have the external shape of one mineral but are composed of another.  The pseudomorph goethite after marcasite forms when marcasite is exposed to oxidizing conditions and starts to oxidize and break down. As the marcasite breaks down, goethite replaces it in the crystal structure, preserving the shape of the original marcasite crystal. The resulting specimen appears as a marcasite crystal, but is actually composed of goethite.

The Farafra Oasis, in the White Desert, has been known for a number of years to deliver incredible pseudomorph specimens. The pseudomorphs occur within the Cretaceous Khoman Chalk, from which the White Desert derives its name.

These specimens are remarkable for their relatively sharp marcasite crystal forms in aesthetic crystal clusters. They are in excellent condition.  This collector's specimen is unique, of great quality and ready for display.

This is a very fine and lustrous Stilbite from Parsboro, Cape d'Or, Nova Scotia, Canada. It was collected in 2002 and is a group of well terminated crystals with nice sharp edges.  

Stilbite is a zeolite mineral appreciated for its delicate crystal formations and pastel hues, ranging from colorless to white, yellow, pink, and peach.  It forms distinctive tabular crystals with a bowtie or butterfly shape and exhibits a vitreous to pearly luster. Commonly found in cavities in volcanic rocks, stilbite is often associated with other zeolite minerals. It is valued for its aesthetic appeal and is believed by some to have calming energy, supporting spiritual growth and emotional healing.

This is a pale green crust of hidalgoite on matrix.  It was named after the place where it was first discovered, the Zimapán mining district, Hidalgo, Mexico.

This is a natural cluster formation of calcite on calcite crystals or two variations of the mineral found in a cracked concretion in a coal mine in Oskaloosa, Mahaska County, Iowa, USA.

It is a specimen consisting of two types of calcite on matrix. The first type is a coating of iridescent, dark calcite on the matrix. The second type are white crystals of calcite.   It is in good condition.  Would be a nice addition to any new or existing collection.

Name: Calcite on Calcite Crystal Cluster
Specimen Size:  Cabinet-Sized
Dimensions:  65x47x32 mm / 2.6x1.8x1.3 inches
Weight: 64 Grams / 2.2 oz

This is a specimen of Star Mica or Muscovite and Quartz cluster.  These clusters show crystals that grow in sheets or book formations.  It is silvery gold with good transparency when held up to the light.  The name Muscovite comes from the term Muscovy Glass which was a name for the thick sheets of Mica used as a substitute for glass Russia. The name Mica is derived from the Greek word that means to split.

On this nice specimen, the matrix faces are covered with beautiful golden yellow point stars of muscovite mica, a typical shape for this rare mica formation. The stars are the result of twinning; the points show a bit of wear but this does not detract from the beauty of such a piece.
