This is an attractive specimen of calcite crystals from the Wessels Mine, Kuruman, South Africa. The entire top surface of the specimen is covered with many sharp well formed calcite crystals. Some are a frosted snow white ball shape which sit amongst a sharper sparkly druzy calcite. It is in excellent condition.
Calcite is found throughout the world in sedimentary, metamorphic, and igneous rocks. Some geologists consider it to be a "ubiquitous mineral" - one that is found everywhere. Calcite is the principal constituent of limestone and marble.

Iceland spar, formerly called Iceland crystal (Icelandic: silfurberg [ˈsɪlvʏrˌpɛrk], lit. 'silver-rock') and also called optical calcite, is a transparent variety of calcite, or crystallized calcium carbonate, originally brought from Iceland, and used in demonstrating the polarization of light.
The most common crystal structure of Iceland spar is rhombohedral, but other structures, such as scalenohedral or prismatic, can form depending on formation conditions. Iceland spar is primarily found in Iceland but can occur in different parts of the world with suitable geological conditions such as China.

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.

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.
Name: Hidalgoite
Specimen Size: Miniature-Sized
Dimensions: 57x35x41 mm / 2.2x1.4x1.6 inches

Origin: Mined in Gold Hill Mine, Gold Hill, Gold Hill Mining District (Clifton Mining District), Tooele County, Utah, USA
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.
Name: Star Mica - Muscovite with Quartz
Specimen Size: Miniature-Sized
Dimensions: 47x43x25 mm / 1.8x1.7x1.0 inches
Weight: 48 Grams / 1.7 ounces

Here we have for you a large 37.3 grams superbly shaped Indochinite Tektite from Maoming City, Guangdong Province, China. Although not a meteorite, tektite is directly linked to them or their impacts, just consider its age of around 780,000 years old.
Tektite can still be interesting because of the persistent mystery has that resisted clear explanations of their creation for generations of geologists. Dimensions are 60x22x21 mm.
This piece displays very well and is a very nice size showing multiple characteristics of its origin. Would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.
