This mineral combination is from a classic locality, the Newfoundland Zinc Mine, which has been closed for many years. This mine was a high grade zinc mine with very little contaminants in the ore which made it easier to mill and produced good concentrate. This site is known for beautiful mineral specimens, particularly sphalerite crystals often associated dolomite.
The sphalerite from this region typically appears as dark brown to black, resinous crystals, sometimes with red or orange undertones due to iron content. These crystals often serve as a striking backdrop for the light-colored dolomite, which forms as rhombohedral or curved aggregates on top. The contrasting colors and textures make specimens from Daniel’s Harbor highly collectible.
Very nice showy material in excellent condition and a collectors dream specimen.
Name: Dolomite on Sphalerite Crystals
Specimen Size: Miniature-Sized
Dimensions: 41x27x19 mm / 1.6x1.1x0.7 inches

This is a beautiful black Biotite crystal book from the Calcite Vein-Dikes of the Grenville Geological Province Ontario, Canada. This specimen is a great example of both the classic crystal shape and attractive dark coloration.
Biotite is rarely considered a valuable mineral specimen, but it can accompany other minerals and compliment them. In Bancroft, Ontario, Biotite forms large crystals with green apatite and hornblende. Single large plates or "books" of biotite can grow to considerable size and can make impressive mineral specimens.
Stand not included.

This amazing specimen of Vesuvianite was collected in the 1960's by A. Stevenson in Harcourt, Ontario, Canada. The specimen is a beautiful rich gemmy green vesuvianite crystal, and is fully terminated. This rare and premium specimen is in excellent condition. A fantastic addition to any collection!
Vesuvianite was first discovered on Mount Vesuvius in Italy in the 18th century, hence its name. It typically occurs as a green, brown, yellow, or blue-green crystal, and is often found in metamorphic and igneous rocks. The alternate name, Idocrase, is from the Greek eidos “form”, and krasis “mixture”, because Vesuvianite often appears to combine the crystal forms of other minerals. It has also been used as a gemstone.

The province of Québec, particularly areas like the Mont-Saint-Hilaire region, is known for producing fine mineral specimens, including albite. In pegmatites, albite often grows alongside minerals like quartz, mica, tourmaline, and spodumene. It forms in environments with slow cooling, allowing for large and well-defined crystals.
Albite is thought to help with decision-making, problem-solving, and overcoming fears of the unknown. Many believe it promotes calmness and adaptability, helping one embrace change with confidence.
Would be a beautiful addition to any new or existing collection.

This is a fine Stilbite, Heulandite and Chabazite specimen from the ZEC near Maniwaki, Québec, Canada. You can see sprays and radial clusters of stilbite with minor heulandite on diopside-K feldspar matrix.
Stilbite, Heulandite, and Chabazite are beautiful zeolite minerals found in the basalt and sedimentary rock formations near Maniwaki, Québec. These crystals often form in delicate, radiating clusters or blocky, tabular structures, showcasing a range of colors from soft pinks and oranges to translucent whites. Stilbite is known for its pearly luster and graceful fan-like formations, while Heulandite displays intricate, layered crystal habits. Chabazite, with its distinctive rhombohedral shape, adds variety to the mineral assemblage. Collectors and geologists appreciate these minerals not only for their aesthetic appeal but also for their fascinating crystal chemistry and association with the region’s volcanic history.
