Minerals

Carletonite is a rare and visually delicate mineral best known for its soft blue color, though it may also appear in pink, white, or colorless forms. It crystallizes in the tetragonal system and has a Mohs hardness of 4 to 4.5, which makes it too soft for most jewelry applications but highly prized by collectors. It displays a vitreous luster and is usually transparent to translucent.

Carletonite was first discovered in the Mont-Saint-Hilaire alkaline complex in Quebec, Canada, which remains the only location where well-formed, high-quality specimens have been found. The mineral was named in honor of Carleton University in Ottawa. Although Mont-Saint-Hilaire is the only confirmed and significant source, there have been occasional reports of possible carletonite occurrences in Russia and the United States. These findings are extremely limited and typically lack the clarity and crystal quality seen in the Canadian material.

Hubnerite is a rare manganese tungstate mineral and the manganese-dominant member of the wolframite series. It typically forms dark reddish-brown to nearly black blade-like crystals with a submetallic to silky luster. This dense mineral is an important tungsten ore and is commonly found in high-temperature hydrothermal veins, often with quartz and fluorite. Specimens from Peru and Colorado are especially well known for their sharp, aesthetic crystal formations.

Zinnwaldite is a rare, lithium-rich mica mineral known for its dark, silvery brown to reddish-brown color. It forms in layered, sheet-like crystals and has a soft, slightly shiny surface typical of the mica group. It was first discovered in the Zinnwald area on the German–Czech border, which is where its name comes from.

Zinnwaldite is believed to promote clarity, balance, and inner strength—making it an excellent companion for decision-making, emotional resilience, and self-trust.

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.
