The Lead–Zinc deposits of Madan Ore Field (Southwest Rhodopy Mountains) were operated by the Turks in the Middle Ages. Greek coins from Tassos island dating from 14th century AD, have been found in the ancient galleries. As well, the name of the Madan field, which in Turkish means Ore, originates from that time. 

The Madan Ore Field is built up mainly of the highly crystalline rocks of the lower (Ar) and upper (Pt) metamorphic units which form the Madan dome structure. The Lead–Zinc deposits of the Madan Ore Field are represented by: 1. Ore veins of Quartz–Carbonate–Sulphide composition, and 2. Metasomatic scarn deposits of Johannsenite–Rhodonite or Quartz–Sulphide composition.

Microcline is one of the most common feldspar minerals. It can be colorless, white, cream to pale yellow, salmon pink to red, or bright green to blue-green. Microcline forms short prismatic or tabular crystals that are often of considerable size: single crystals can weigh several tons and reach yards in length. Crystals are often multiply twinned, with two sets of fine lines at right angles to each other. This gives a plaid effect that is unique to microcline among the feldspars.  The nice patch of Quartz crystals makes this a spectacular piece. 

This is a quality specimen that would be a beautiful addition to any new or existing rock collection.

Amphibole is a group of dark-colored, complex silicate minerals that form in a variety of geological settings.  The amphibole group includes several mineral species, such as hornblende, tremolite, actinolite, anthophyllite, and others. Each variety has its own unique chemical composition and physical properties.

Amphibole minerals can exhibit a range of colors, including dark green, black, brown, and even colorless. They often have a prismatic crystal habit, forming elongated crystals with distinct cleavage angles.  They are commonly found in igneous and metamorphic rocks. They crystallize in magma and can also form during metamorphism when pre-existing rocks are subjected to high pressure and temperature.

This top specimen is in very good condition. Would be a beautiful addition to any new or existing collection.

This is an attractive specimen consisting of natural pale gray transparent crystals of Calcite on a green crystal matrix from Morocco.  Very beautiful material.

Calcite is found throughout the world in sedimentary, metamorphic, and igneous rocks. Some geologists consider it to be a "ubiquitous mineral" - one that is found everywhere. Calcite is the principal constituent of limestone and marble.

This is a large sparkly cluster of beautiful multi-colored bladed barite and some Cerussite crystals.  Barite crystal formations grow in parallel sheets that almost appear fibrous. It is well-known for its great range of colors and varied crystal forms and habits. Cerussite is commonly known as white lead and is an important ore mineral.  It consists of lead carbonate which crystallizes in the orthorhombic system.  Its color will vary depending on the composition and structure, with colorless, white, grey and green tinted, being the most common colors of crystals found.

Celestite, also known as celestine, typically ranges in color from light blue to pale blue, though it can also be colorless, white, or shades of yellow and pink.  Celestite is a strontium sulfate mineral which crystallizes in the orthorhombic crystal system, typically forming well-defined, prismatic crystals.  This celestite specimen is a nice example of a prismatic crystal form.

Celestite is often associated with calming energy and is believed to aid in meditation and spiritual development. It is said to promote mental clarity and enhance communication with higher realms.

This is an incredible Korra Korrabes meteorite end cut of 24.1 grams, it measures 37x27x22 mm. This gorgeous classified meteorite is an H3 Chondrite and part of a 22 kg stone plus 11 smaller pieces totaling ~18 kg that were found November 1996 in a dry river bed by a farmer who was searching for Gibeon irons.

People searching with metal detectors recovered hundreds of additional buried, more weathered pieces within 50 m of the original material since 2000 November, bringing the total mass to ~120–130 kg. The largest specimen was used in a garden wall until August 2000.

This amazing piece was professionally prepared and would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.

This is an attractive shiny spray of metallic stibnite crystals. This outstanding specimen came from the Xikuangshan mine of China.

Stibnite is a lead-gray mineral occurring as striated prismatic crystals, that are made up of antimony sulfide and is the main ore of antimony. It often forms groups of long, shiny metallic crystals radiating out at different angles.

 NOTE: Stibnite (antimony) is toxic and can be harmful if inhaled or swallowed. While a crystal sitting on your shelf doesn't pose a health risk you should always wash your hands after handling and keep it out of reach of children.
