Peridotite xenoliths in basalt. Peridote or olivine is a magnesium-iron silicate mineral commonly found in the Earth’s mantle. The photos show “chunks” of green peridote crystals that have broken off from a larger mass and floated into the magma within the Earth’s mantle, before being exposed at the Earth’s surface. Magnesium-iron rich olivine is also commonly found in meteorites. Pallasite meteorites contain olivine crystals mixed with molten iron from the cores of large, diffentiated asteroids. Click here to see extraterrestrial olivine.

Emile Pingat


Emile Pingat had a proclivity for designing carefully finished dresses and outerwear which made him one of the top three French fashion designers during the second half of the 19th century. Active between 1860 and 1896, Pingat was adroit at manipulating multiple textiles and trimmings into a cohesive and elevated garment. He was inspired by design elements of other cultures and often reinterpreted them into his own work, making them unique and intriguing. His elaborately decorated and impeccably tailored outwear was particularly sought after.
