Pyroxene autige. Polarised light micrograph of a thin section of augite, an essential part of igneous rock, basalt and gabbro. Its also quite common in metamorphosed iron formations

Jade group
A selection of rough and worked specimens of jadeite and nephrite. Jade is a gemstone and ornamental stone

Chrome diopside
Two variations of a diopside gemstone (calcium magnesium silicate). Left: Deep-green faceted cut stone; locality unknown. Right: Small translucent green detached crystal from Outokumpu, Finland

Rhodonite
A pink specimen of rhodonite (manganese iron magnesium calcium silicate). Rhodon is greek for rose. Specimen from the Natural History Museum, London

The Abee EH4 enstatite chondrite
Abee fell in Canada in 1953. The cut surface clearly shows the metal-rich and brecciated texture of Abee

Jadeite crystal and cut stone
Jadeite comprises of (sodium aluminum iron silicate) and is actually not a mineral outright, but is a variety of the mineral actinolite. Specimens from the Natural History Museum, London

Spodumene
A specimen of the mineral spodumene (lithium aluminium silicate). This mineral comes in two varieties, Kunzite and Hiddenite

Enstatite comprises of (magnesium silicate) and derives from the pyroxene group. Specimen from the collections of the Natural History Museum, London

Microscope image of the Johnstown diogenite. Diogenites are coarse grained and composed primarily of one mineral, pyroxene. Field of view is 2.5mm across

Microscope image of the Zagami shergottite. The fractures in the pyroxene mineral grains and the paler patches of glass show that the rock has been shocked. Field of view is 5mm

Microscope image of the Brachina meteorite, the type specimen of the Brachinite meteorites. Brachinites are composed mostly of olivine with minor amounts of pyroxene and plagioclase

Radial pyroxene chondrule
Microscope image of a radial pyroxene chondrule from the ALH 88036 (H3.4) ordinary chondrite. The chondrule is about 2mm across

Spodumene crystal and cut stone
Large spodumene (Lithium Aluminum Silicate) crystal and cut gemstone from Brazil

Kunzite crystal and cut stone
Strongly dichroic pink kunzite crystal and faceted kunzite. Kunzite (lithium aluminum silicate) is the pink variety of spodumene and is pleochroic

Jadeite carved dish from China

Polished slab of rhodonite
A pink specimen of rhodonite (manganese iron magnesium calcium silicate). Rhodon is greek for rose

Eroded glacial landscape, British Columbi

Pyroxene, a fascinating group of minerals and crystals, encompasses various members like kyanite, asbestos, augite, diopside, bronzite, hypersthene, wollastonite. These silicates form the pyroxene group and display mesmerizing colors in lithographs. Delving deeper into the Earth's structure reveals the presence of pyroxenes in the lower mantle. A cross-section of our planet showcases their significance in shaping its composition and dynamics. Even beyond our planet's boundaries, pyroxenes leave their mark. Chondrite meteorites C013/7777 and C013/7776 bear witness to these remarkable minerals' extraterrestrial existence. HED meteorites captured through light micrographs (C013/7774) offer glimpses into their celestial journey. Intriguingly polarized under a microscope (C013/4592), pyroxene augite exhibits stunning patterns that captivate scientific minds and inspire awe among enthusiasts. The allure of pyroxenes extends to precious gemstones as well. The Jade group boasts exquisite specimens like chrome diopside and rhodonite which showcase nature's artistry at its finest. One cannot overlook the enigmatic beauty found within the Abee EH4 enstatite chondrite—a testament to how they can astound us with their unique characteristics even when part of cosmic objects. Finally, jadeite crystal and cut stones exemplify how humans have harnessed these captivating minerals for adornment throughout history—transforming them into symbols of elegance cherished by many cultures worldwide.
