Mineral Type & Crystal Species
Hiddenite is the green variety of spodumene, a lithium aluminium inosilicate with the chemical formula LiAlSi₂O₆. It belongs to the pyroxene group of minerals and crystallises in the monoclinic crystal system. Spodumene typically forms elongated prismatic crystals with prominent vertical striations and well-defined cleavage.
The green colour of hiddenite is commonly attributed to trace amounts of chromium, which substitute within the crystal lattice during formation. Shades can range from pale yellow-green to vibrant emerald-toned green, depending on trace element concentration and geological conditions.
Spodumene has a Mohs hardness of approximately 6.5 to 7, making it relatively durable but with perfect cleavage in two directions. It exhibits a vitreous to slightly pearly lustre and may be transparent to translucent depending on internal inclusions and crystal integrity.
Geological Formation & Locality
Hiddenite forms in granitic pegmatites, which are coarse-grained igneous rocks that crystallise from the final, volatile-rich stages of magma. These pegmatites are often enriched in rare elements such as lithium, beryllium, and tantalum.
The Karelia region of Russia is known for complex Precambrian geological terrains, including granitic intrusions and pegmatitic systems. Within these environments, spodumene develops as large prismatic crystals associated with quartz, feldspar, mica, and occasionally tourmaline or beryl.
The geological history of Karelia, characterised by ancient crystalline shields and tectonic activity, provides the conditions necessary for the formation of lithium-rich pegmatites where hiddenite can occur.
Physical & Optical Characteristics
This hiddenite specimen displays natural green coloration with potential internal zoning, inclusions, or growth features typical of pegmatitic minerals. Vertical striations may be visible along prism faces if present. The stone may range from translucent to more transparent areas depending on crystal quality.
Under strong light, hiddenite can show subtle pleochroism, appearing slightly different shades of green when viewed from different angles. Natural internal features are part of the mineral’s formation history and add to its authenticity as a geological specimen.
No treatments or enhancements are implied; the specimen is presented as a natural mineral example.
Historical & Traditional Context
Spodumene varieties, including hiddenite and kunzite, have been valued by collectors and gem enthusiasts since their identification in the 19th century. Hiddenite is named after William Earl Hidden, an American mineralogist who first documented the green variety of spodumene.
In spiritual traditions, green crystals are sometimes symbolically associated with growth and balance. These associations are cultural and belief-based rather than scientific.
Collectors Display & Gifting
This Hiddenite mineral from Karelia, Russia makes a distinctive addition to any mineral collection, especially for collectors interested in lithium-bearing pegmatite minerals or Russian localities. Its natural green colour and prismatic structure provide strong visual appeal in a display cabinet or educational collection.
You will receive the exact specimen shown in the photographs, securely packaged and accompanied by a Certificate of Authenticity lifetime guarantee card. A genuine hiddenite mineral specimen from Karelia, selected for quality and geological interest.
