Minerals

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.

Wolframite is the principal and primary ore mineral of tungsten, and commonly associated with the tin ore in and around granite country rocks. Wolframite is an iron manganese tungsten oxide mineral.

Would be a beautiful addition to any new or existing collection.

Lepidolite is a lilac-gray or rose-colored member of the mica group of minerals.  Because lepidolite is a lithium-bearing mica, it is often wrongly assumed that lithium is what causes the pink hues that are so characteristic of this mineral. Instead, it is trace amounts of manganese that cause the pink, purple, and red colors.  The most notable and certainly the most studied of these deposits is the Brown Derby #1 Pegmatite, located in the Ohio City/Quartz Creek District, approximately 18 miles northeast of Gunnison in the high mountains of Central Colorado.

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

This is from Tanco mine, a beautiful combination of a nicely formed and colorless(white) Spodumene on top of Quartz matrix.  This fabulous specimen is fluorescent under UV light.

Spodumene is a pyroxene mineral and is a source of lithium. It occurs as colorless to yellowish Triphane, purplish or lilac kunzite, yellowish-green or emerald-green hiddenite, prismatic crystals, often of great size with single crystals of up to 14.3 m (47 ft) in size being reported.

Kunzite is the best-known variety of the mineral spodumene.  Kunzite gets its delicate color from trace amounts of manganese.

Mesolite is a fragile member of the zeolite group and forms almost exclusively in delicate, needle-like crystal habits.  From the Greek for meso = middle and lithos = stone, for its chemical composition is between that of natrolite and scolecite.  This is a very nice specimen consisting of a large vug in basalt completely covered by white needle.

This specimen will come protected in its specimen display box with a Canagem Specimen Mineral Card.

Pyrite is a fascinating mineral also known as "fool's gold" because of its metallic luster and brassy yellow color, which can resemble gold. It often forms in cubic crystals or as nodules in sedimentary rocks.  It gets its name from the Greek word "pyr," meaning fire, as it can produce sparks when struck against metal or another hard material.

An interesting thing about pyrite is its association with ancient civilizations. It has been discovered in artifacts from ancient Egypt and was used for ornamental purposes in jewelry.

Pyrite is believed attract financial success and offer protective qualities against negative energies. It is thought to boost confidence, inner strength, creativity, and focus.

These beautiful pyrite cubes are are Thumbnail sized specimens that were mined in Navajun, Spain.  They are top specimens and are in very good condition. Would be a beautiful addition to any new or existing collection.

The weight and dimensions of the cubes are as follows:

This spectacular rock specimen consists of alternating layers of light blue-green amazonite and light grey smoky quartz topped by a biotite mica (muscovite) crystal. This special material is found in proximity of pegmatite melts to the surrounding country rock and is the result of quick cooling of the melt.

The term graphic originates from the Greek word Graphos or the Latin word Graphus which means to write. It denotes the script-like appearance that resembles cuneiform or runic writings where the darker, glassy quartz appears as letters or characters written on a lighter or whitish feldspar groundmass. This top specimen has it all and is in great condition. Will mesmerize you for hours examining all angles of this fantastic specimen. Would be an amazing addition to any new or existing collection.
