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.

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

Wavellite typically forms as radiating, spherical clusters or botryoidal (grape-like) aggregates, often appearing as green, yellow, brown, or even blue clusters on a host rock. The mineral typically forms in low-grade metamorphic rocks and phosphate-rich environments, often associated with minerals like quartz, variscite, and limonite.

Wavellite is found in several locations worldwide, with Arkansas, USA being one of the most famous sources, producing well-formed green botryoidal specimens. Other notable locations include England, Bolivia, Brazil, Germany, and Australia.

It is believed wavellite is linked to clarity, insight, and emotional balance, helping to provide a broader perspective on situations. It is sometimes associated with the heart chakra, thought to encourage compassion and emotional healing.

Pyrite from Bolivia is known for forming beautiful, well-shaped crystals, often appearing as sharp cubes, pyritohedrons (12-sided shapes), or even complex, stepped growth patterns. Bolivian pyrite tends to have a bright, brassy gold color with a good metallic luster, and it’s often found in association with other minerals like quartz or galena. 

Much of the pyrite from Bolivia comes from mining regions such as Potosí and Oruro, areas famous for their rich mineral deposits. While pyrite is common around the world, Bolivian specimens are valued for their attractive crystal habits, clean formations, and the quality of the material.

Pyrite is known as a stone of protection, abundance, and confidence.  It is believed to shield against negative energy and promote mental clarity and willpower. 

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

At this famous Canadian site, siderite typically forms as small, brown to tan crystals, often rhombohedral in shape, growing over or alongside white to gray albite. Scattered among them, tiny, sharp zircon crystals can appear — often reddish-brown, yellow, or even colorless depending on the exact specimen.

Mont Saint-Hilaire is renowned for producing rare and unusual mineral combinations, and specimens like this highlight the diversity and richness of the location. While each mineral is interesting on its own, having siderite, albite, and zircon together in one piece makes it a well-balanced and attractive collector’s specimen, especially for those who appreciate the geology of the region

This is a very typical specimen of MSH and is in very good condition. Would be a beautiful addition to any new or existing collection.

Iceland Spar, also known as optical calcite, is a clear, transparent variety of calcite famous for its unique optical property called double refraction. When you place the crystal over text or an image, it appears doubled — a visual effect that occurs because light splits into two rays as it passes through the crystal. This fascinating trait made Iceland spar historically important in early optical instruments and scientific studies, including navigation and the development of polarizing microscopes.

It’s typically colorless or very lightly tinted and forms naturally in sharp, rhombohedral shapes. High-quality Iceland spar is most famously found in Iceland, though it also occurs in places like Mexico, the U.S., and China.

Iceland Spar (optical calcite) is often associated with clarity, insight, and truth. Because of its double refraction property, some see it as a symbol of seeing beyond surface appearances — helping to highlight different perspectives or reveal hidden aspects of a situation. It's thought to support clear thinking and honest communication, making it a favorite for meditation or decision-making spaces.

Gormanite is a rare phosphate mineral best known for its striking blue to greenish-blue color, often forming as fibrous or radiating crystal clusters. It was first discovered in Yukon, Canada, and is named after Canadian mineralogist Don Gorman. 

Due to its rarity and delicate crystal habit, gormanite is primarily of interest to collectors and mineral enthusiasts. Well-formed specimens are appreciated for their intense color, silky luster, and often intricate, fibrous formations. Gormanite is relatively soft (around 4.5–5 on the Mohs scale) and fragile, so it's best suited for display rather than handling.

Howlite was discovered near Windsor, Nova Scotia in 1868 and named after Henry How, a Canadian chemist, geologist, and mineralogist.  It often forms in nodules which resemble cauliflower heads. The nodules are opaque, white with gray or black veins, often showing web-like pattern. 

Howlite is said to be an extremely calming stone, it can be an excellent antidote to insomnia.  It is also said that Howlite teaches patience and helps to eliminate anger and strengthens positive character traits.
