Crystals & 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.

Kupletskite is a rare and complex titanium-bearing silicate mineral most famously found at Mont Saint-Hilaire in Quebec, Canada. It typically appears as tiny brown to reddish-brown crystals, often with a glassy or resinous luster. The crystals are usually slender and prismatic and may occur alongside other rare minerals that Mont Saint-Hilaire is known for.

Due to its rarity and specific geological conditions needed for formation, kupletskite is primarily of interest to serious collectors and mineralogists, especially those focused on rare earth or alkaline complex minerals. It’s not commonly available in large or showy specimens, so even small, well-formed crystals are considered notable.

This beautiful and rare specimen of Kupletskite from world famous Mont St-Hilaire, Quebec, would be a great addition to any collection.

Name: Kupletskite
Specimen Size:  Miniature-Sized
Dimensions:  30x15x15 mm / 1.2x0.6x0.6    inches

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.

This is a nice group of small yellow wulfenite crystals on matrix from Total Wreck Mine, Arizona.  Wulfenite from the Total Wreck Mine is known for producing small but attractive crystals, usually in shades of yellow to orange-yellow. The crystals from this mine tend to be thin, tabular, and sometimes slightly translucent, often growing on a contrasting, earthy matrix.

While the Total Wreck Mine isn’t as famous as places like the Red Cloud Mine for wulfenite, it has still yielded pieces that are valued by collectors, especially because Arizona as a whole is renowned for producing some of the world’s finest wulfenite. Specimens from Total Wreck are typically more modest in size and brightness but are appreciated for their historic mining context and authentic desert character.

Wulfenite is often associated with creativity, emotional balance, and perseverance. Some believe it helps connect the heart and the will, encouraging people to follow their passions even through difficult or uncertain times. Wulfenite is also thought to support emotional healing by helping release old attachments and clearing a path for new experiences.

The specimen is in good condition and is a colorful and really beautiful specimen. 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.

Astrophyllite is a striking and rare mineral known for its bronze to golden-bladed crystals that radiate like starbursts, often embedded in a dark matrix of other minerals. The name comes from Greek, meaning “star leaf,” referring to its star-like crystal formations. It  is found in locations such as Russia, Norway, Greenland, and Canada.  This specimen of Astrophyllite crystals originates from the world famous site of Mont Saint-Hilaire, Quebec. 

Astrophyllite is often seen as a stone of inner illumination and self-discovery. Some believe it helps reveal hidden potential and encourages personal truth, making it a supportive companion during times of change or reflection. It’s sometimes associated with letting go of the past and embracing a more authentic path forward.

This specimen is in very good condition and displays very well.  Make this a special specimen in your collection.
