Though Haidinger was the first to describe siderite in 1845, the mineral has been used and known throughout the world since ancient times. In that vein, siderite is one of the minerals collected by researchers at the Switzerland research university ETH Zurich to determine what Earth's climate was like during the Paleocene and Eocene eras.

Magnetic, Moss effect, and thermal properties have been evaluated for specimens of the mineral ankerite and are contrasted with similar measurements reported for the mineral siderite to determine if ankerite (and ferroan dolomite), like siderite, may be important in paleomagnetism as a producer of secondary, spurious remanent moments as the result of oxidation in air.
Item Description. Leadville was one of the great mining towns in Colorado, producing some iconic mineral specimens. This is a lovely Siderite specimen from the Irene Shaft (sometimes called the Irene Mine but it's actually part of the Black Cloud Mine) featuring several rhombic crystals measuring up to 6 mm, with a greenish-brown color, and a satiny interior …

Collected in the early 1980s, in good condition and quite nice for this locality and species.
Siderite is an ore of iron when found in sufficient volume to be economically recoverable. It was named in 1845 from the Greek word meaning "iron," in allusion to its composition. It is most often found in bedded sedimentary deposits with shales and coal beds and also as bog deposits. ... Mineral Photos courtesy of R.Weller/Cochise College ...
SIDERITE. HISTORY, NAME, LOCALITIES: Siderite, pronounced SYE-der-ite, has been known since antiquity and was recognized as mineral species in 1845. Its name stems from the Greek sideros, meaning "iron," alluding to its composition. Siderite is abundant and widely distributed with notable collecting localities in Germany, England, Portugal ...
Phenakite, sometimes also spelled Phenacite, is a rare beryllium silicate mineral with the chemical formula Be₂SiO₄. Phenakite is prized for its crystal clarity, brilliance, and hardness, making it a …
Siderite is both an iron ore and gangue mineral. Its principal economic value lies in its high iron content and the absence of process contaminants such as sulfur or phosphorous.

The sharp, highly lustrous chalcopyrites feature most prominently at the top (the way I would display it) and the largest is a parallel growth group 1.4 cm across. The siderite on this specimen is as good as the siderite on any of these I have seen – sharp, clean, lustrous and translucent.
Siderite. specimen number: 1951665. location: Mt. St. Hilaire, Quebec, Canada. description: Brown semi-lustrous large blocky rhombohedral crystals of siderite are scattered very aesthetically over the front of this 26.0 x 16.0 x 15.0 cm matrix. In excellent condition for one of these, the largest siderite crystals measure to 4.5 cm in size.

Siderite occurs as clay ironstone, an impure mixture of siderite with clay minerals. It may form concretions or concentric layers. It may also occur as black-band ore, which can form extensive stratified beds admixed with shales, other carbonates, and coal. Siderite is also formed as iron rich waters replace Ca in limestone.
Siderite forms as a sedimentary precipitate, in hydrothermal veins, in metamorphic rocks formed from such protoliths, and, rarely, in pegmatites. In sedimentary environments it forms in extensive beds of banded iron formations and as more localized deposits of bog-iron ore. It readily weathers to iron oxides.

Introduction: siderite is widely developed in a range of geological settings, in particular some hydrothermal veins (where it may be the chief gangue mineral and may also be mined if pure enough), and in sedimentary rocks, where it is often an important constituent of ironstones. Siderite, like other iron-bearing carbonates, is white to creamy-yellow when unweathered: …

This stone is too soft to be cut and is hence rarely faceted as a gemstone. As it is a carbonate, it would give effervescence (bubbling) when in contact with acids; strong eye visible doubling due to the high birefringence. Siderite, like most carbonates, is highly birefringent.
