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 beautiful specimen of golden brown Vesuvianite crystals on a white carbonate matrix from Mexico. A great addition to any collection! It was first discovered on Mount Vesuvius in Italy in the 18th century, hence its name. Vesuvianite typically occurs as a green, brown, yellow, or blue-green crystal, and is often found in metamorphic and igneous rocks. The alternate name, Idocrase, is from the Greek eidos “form”, and krasis “mixture”, because Vesuvianite often appears to combine the crystal forms of other minerals. It is used as a gemstone.

This is an Adamite Crystals on Limonite matrix mined in Mina Ojuela, Mapimi, Durango, Mexico.  Adamite typically occur as small, brightly colored, prismatic or blocky crystals, or as crusts or aggregates. It is commonly found in association with other minerals such as limonite, calcite, and smithsonite.  Adamite colors include green, yellow, white, and reddish-brown. The green color of adamite is caused by the presence of traces of copper in its crystal structure.  One of the unique features of adamite is its strong fluorescence under ultraviolet (UV) light. It can exhibit vibrant green or yellow fluorescence.

Adamite was first discovered in 1866 in the Ojuela Mine in Durango, Mexico. It was named after French mineralogist Gilbert-Joseph Adam (1795-1881), who studied the mineralogy of the mine.

Adamite is associated with joy, creativity, and the balancing of energies. Some believe it can enhance one's ability to express themselves and promote a positive outlook.  It is highly valued by collectors for its bright colors and distinctive crystal habits and would be a great addition to any new or existing collection.

Aegirine, also known as acmite, is a rare and stunning black mineral. It is found in many locations around the world, but its most prized specimens come from Mount Malosa in Malawi, where it is often found in association with Microcline.

Aegirine is usually black, greenish-black, or brownish-black in color and has a glassy or vitreous luster. It has a hardness of 6 to 6.5 on the Mohs scale, which means it is relatively hard and durable. Aegirine is also known for its straight, needle-like crystals that can grow up to several centimeters in length.  

Microcline, a member of the feldspar mineral family, is known for its beautiful color variations and distinctive twinning patterns. When paired with Aegirine, the result is a striking and eye-catching contrast of colors.

Aegirine is believed to have properties associated with protection, energy balancing, and spiritual growth. Microcline, being a feldspar, is often linked to creativity and intuition. The combination of these minerals is thought to enhance their individual metaphysical properties.

This Aegirine on Microcline crystal is the perfect combination for those looking for a unique and beautiful addition to their mineral collection!
