Eosphorite is a beautiful and unique mineral that is known for its pinkish-purple hue and crystalline structure. It is a member of the phosphate mineral family and its chemical formula is MnAlPO4(OH)2·H2O.Eosphorite was first discovered in Sweden in the early 1800s and has since been found in various locations around the world, including Brazil, Russia, and the United States. Some of the highest quality and most beautiful Eosphorite is found right here in Maine! It typically forms in granite pegmatites, which are rock formations with large crystals that form from slow cooling magma.The most notable feature of Eosphorite is its color,...

Rhodonite - a fascinating mineral that is prized for its striking coloration and many unique properties.First, let's talk about what Rhodonite actually is. It is a manganese inosilicate mineral that is typically found in metamorphic rocks, such as inclusions in granite or gneiss. It is known for its distinctive pink to red coloration, which is caused by the presence of manganese ions within its crystal structure.One of the most notable features of Rhodonite is its resistance to weathering and erosion, which makes it a popular material for use in construction and sculpture. Because of its durability, it is often used...

Corundum is a mineral with the chemical formula Al2O3, and is one of the hardest minerals known, with a Mohs hardness of 9. This characteristic makes it highly valued for its use in abrasives and cutting tools.It is commonly found in metamorphic rocks such as schist and gneiss, as well as in igneous rocks such as syenite and nepheline syenite. It can also be found in alluvial deposits where it has been transported by water.Corundum is typically transparent or translucent, and can come in a range of colors including blue, pink, yellow, green, and black. The coloration is often due...

Cinnabar is a bright red mineral that is primarily composed of mercury sulfide. It is a highly valuable mineral due to its use in the production of mercury, which has been used for centuries for various purposes including the manufacture of thermometers, barometers, and fluorescent lamps.Cinnabar is found in many locations around the world, including Spain, Italy, China, Mexico, and the United States. Some of the largest and most beautiful specimens of Cinnabar have been found in China, where it has been mined for over 2,000 years.The mineral has a distinct, deep red color that is highly prized by collectors...
