Pseudomorph Goethite After Marcasite | Prophecy Stone | 17-23 gr | Farafra Oasis, Egypt
You will receive one of the Pseudomorphs pictured.
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.

Tanzanite is renowned for its intense blue and violet colors, but can also be golden, green, lilac and peacock (blue and green). The sole source of tanzanite is the Merelani Hills in northern Tanzania. Discovered in the 1960s, tanzanite is considered rarer than diamonds due to its single-source origin. The mines in Tanzania are exhaustible, adding to the gemstone's allure.
With a hardness of 6.5 to 7 on the Mohs scale, tanzanite is relatively soft compared to some other gemstones. As a result, it requires gentle care to prevent scratches or damage.
Tanzanite is believed to aide with spiritual awareness, insight, and communication. Some attribute it with calming energies and the ability to enhance psychic abilities.

This is a rare and fantastic 40 gram Libyan Desert Glass from Kuffra, Libya, with dimensions of 57x39x26 mm.
Although its exact origin is still debated, the leading theory suggests it was formed by a high-energy event, such as a meteoric impact or airburst, that melted the desert sand directly where it lay, without being ejected into the atmosphere and re-entering. This results in different physical characteristics compared to tektites. Libyan Desert Glass is found specifically in the Great Sand Sea of the Eastern Sahara, within a more localized area spanning parts of western Egypt and eastern Libya.
This piece displays extremely well and is a quality translucent specimen. It has an aesthetic shape with a beautiful wind eroded body from the years spent in the Desert. Would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.
