Catalog Search Guide
You can search our catalog using different mineral attributes. For example, you can search by color such as green, yellow or purple, or by chemical elements such as uranium, calcium or iron, or by mineral groups such as phosphate, silicate or carbonate. You can also filter by crystal habit like crystal, geode or crystal on matrix, by specimen size such as thumbnail, small, medium or cabinet, and by features such as radioactive or fluorescent minerals.
Azerbaijan
Straddling the Greater and Lesser Caucasus at the crossroads of Europe and Asia, Azerbaijan is a country of striking geological diversity, shaped by ancient volcanic arcs, skarn contact zones, and one of the densest concentrations of mud volcanoes on Earth. The mountainous Lesser Caucasus, particularly around Dashkesan, hosts classic skarn-magnetite iron deposits alongside historically important cobalt mineralization (cobaltite, glaucodot), while the nearby Zaglik deposit is renowned as one of the largest alunite occurrences in Europe. Further southeast, the Gadabay (Gedabek) copper-mining district has yielded chalcopyrite, pyrite, sphalerite, and galena from copper-pyrite and porphyry-copper formations, and volcanic rocks in this same region are noted for gem-quality tourmaline.
The Nakhchivan Autonomous Republic, an exclave bordered by Armenia, Iran, and Turkey, is one of the country's most mineralogically significant regions. Mount Kaputjugh near Ordubad is a recognized source of well-formed quartz and rutile, while the Julfa district's Dardagh arsenic field has historically produced orpiment, realgar, and arsenopyrite in a distinctive shtok-shaped ore body worked until the mid-20th century. Nakhchivan is also noted for rock salt deposits at Nehram and Düzdağ, extensive dolomite, and skarn-related gem minerals including garnet and amethyst, associated with the Ordubad granitoid batholith. In the Khanlar region, volcanic country rock has furnished attractive chalcedony, agate, and heliotrope (bloodstone), all prized by collectors of ornamental silica minerals.
Beyond these classic hardrock localities, Azerbaijan's Absheron Peninsula and Baku area are famous worldwide for petroleum geology and the historic Bibi Heybat oil field, while the Balakan-Zakatala zone hosts important polymetallic deposits such as Filizchay, rich in lead-zinc mineralization with associated copper, cadmium, gold, and silver. Gold occurs widely through the Lesser Caucasus and Nakhchivan at localities like Söyüdü, Gədəbəy, and Ordubad's Paragachay district, often accompanied by silver and molybdenum. For collectors, Azerbaijan offers an underexplored but genuinely rewarding frontier: a rare convergence of Alpine-type quartz and rutile, classic arsenic-sulfide assemblages, skarn cobalt-iron ore minerals, and colorful chalcedony varieties, all tied to a complex Caucasian geology that remains far less picked-over than better-known European mineral districts.
