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 nice 45.34 gram natural untreated Indochinite Tektite from Maoming City, Guangdong Province, China. It is almost round at 40x32x29mm in size. 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 just because of the persistent mystery that resisted clear explanations of their creation for generations of geologists.
This piece displays very well and is a very nice size showing multiple characteristics of its origin. It has a rounded shape with a beautiful pitted body. Would make a beautiful addition to any collection or start one today.
Apophyllite is a mineral known for its distinctive crystal formations, often occurring in clusters with a unique beauty. Its crystals are usually colorless or white, allowing them to be transparent or translucent. Although, some specimens may exhibit a greenish, yellowish, or pinkish tint due to the presence of impurities.
Prehnite can form prismatic, tabular, or pyramidal crystals, but usually occurs in botryoidal, reniform, stalactitic, granular, or compact habits. It is usually green in colour, but may be white, colourless, yellow, or gray. It has a colourless streak. Prehnite is transparent to translucent, with a vitreous to pearly luster. Prehnite forms in cavities in basaltic lavas.
Apophyllite is believed to promote self-reflection and authentic self-expression, helping to reduce stress, release mental blockages, and overcome anxiety by revealing truth and facilitating the release of suppressed emotions. Prehnite is considered a stone of unconditional love, known for its healing properties, especially for healers, and is thought to bring harmony to spaces, assist in decluttering, and create a healing sanctuary, particularly when used in gardens.
