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.
This specimen is remarkable for its relatively sharp marcasite crystal form. It is in excellent condition.

Aegirine, also known as acmite, is a rare and stunning black mineral. It is found in many locations around the world, and this outstanding specimen comes from the Poudrette Quarry at Mount Saint Hilaire, 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!
