Boulangerite typically forms in a unique crystal habit of fine acicular crystals that appear as woven, hair-like fibers. The thin fibers, which can be very thick covering an entire specimen, or thinly spaced on a matrix, are often bent or interwoven due to their flexibility.Boulangerite also forms as dense, hairy inclusions within other crystals, especially Calcite and Quartz.
The name Tantalite has been discredited by the IMA, with the more specific designations of Tantalite-(Fe) (also known as Ferrotantalite), and Tantalite-(Mn) (also known as Manganotantalite) being used for this mineral's IMA-accepted nomenclature.Ferrotantalite is always dark and opaque; Manganotantalite is usually reddish-brown and may exhibit transparency.
Most Fluorite gemstones are from deeply colored stones, but they can also be cut from the less intense color forms. The most popular color for Fluorite is purple, and deep purple Fluorite can closely resemble Amethyst.Fluorite is often brightly fluorescent in ultraviolet light.In fact, the term fluorescence is derived from Fluorite. Due to the very low hardness and perfect cleavage of …
Localities where collection-worthy Gibbsite specimens have been found are very sporadic. The type locality where this mineral was first described is Richmond, Berkshire Co., Massachusetts. An outstanding, aesthetic green botryoidal form resembling Prehnite has been recently described in Xianghualing, Linwu, Hunan Province, China; and a one time find of bright greenish-blue …
The variation of iron in Pyrrhotite's structure is also responsible for more than one crystal symmetry type, allowing it to form in both hexagonal and monoclinic symmetries. Multiple crystal symmetries should technically classify Pyrrhotite as a mineral group rather than a single mineral, but a sub-classification is rarely made due to polytypes appearing similar and perhaps even …
This Fluorite gemstone guide lists qualities of the Fluorite gem type, including stone colors, common names, meanings, gemstone hardness and more.
Among the most noteworthy sources of Elbaite is the state of Minas Gerais, Brazil, where outstanding forms and colors of this beautiful Tourmaline are found in numerous pegmatite localities. Specific famed locality names in Minas Gerais include Aracuai, Barra do Salinas, Conselheiro Pena, Golconda, Governador Valadares, Itambacuri, Ouro Preto, Sao Jose do …

Rock and Mineral Planet is a resource of information and pictures about rocks and minerals as well as other content related to rocks and minerals. ... What are the Differences Between Rocks and Minerals: Best Ways to Identify Fluorite: …
Fluorite is a favorite among collectors because of its vast range of colors, making it one of the most colorful minerals in the world. You can find fluorite in deep blue, vivid purple, sunny yellow, crystal clear, and even …
Fluorite is found as a common gangue mineral in hydrothermal veins, especially those containing lead and zinc minerals. It is also found in some greisens, granites, pegmatites and …
Stilbite is a common member of the zeolite group, and is found in most of the world's important zeolite deposits. Since its original classification, Stilbite was always regarded as a single mineral species with a slightly variable elemental makeup. In 1997, the Zeolite Subcommittee of the IMA divided this mineral into individual sub-species, thereby regarding Stilbite as a series of two ...

Fluorite identification is easy when you use effective identification techniques. Discover fluorite's streak color, specific gravity, and index of refraction.
Fluorite is actually a colorless, clear mineral when it lacks these impurities. It still fluoresces underneath a black light, but it often appears clear or milky white. The formula for pure fluorite is actually pretty simple: CaF2.
Clinozoisite is the same as Zoisite but crystallizes in the monoclinic system, which scientifically classifies it as an individual mineral species. Clinozoisite is also almost identical in composition to Epidote but lacks significant iron in its structure.It forms a series with Epidote, and in many cases the actual distinction between these two minerals cannot be made.
Fluorite is a colorful mineral that comes in many different forms. Some good examples of the different types of fluorite include Blue John fluorite, Tiffany Stone, and …

Borax occurs in arid regions, forming from evaporation of saline lakes. Borax is also synthetically formed as a by-product of mining operations of borate deposits, and most of the specimens from the famous mine at Boron, California, are formed this way. The first Borax specimens came several dry lake deposits in Tibet. They were shipped in large quantities by ancient caravans …
Scapolite is a mineral series consisting of two very similar minerals: sodium-rich Marialite and calcium-rich Meionite.The two Scapolites also differ in that Meionite has a carbonate radical in place of chlorine that is present in Marialite. The two Scapolite minerals are often visibly indistinguishable from each other, and they also form unclassified intermediary examples …
