Plagioclase Feldspar Collection

Polarised LM of a thin section of gabbro rock
Gabbro. Polarised light micrograph of a thin section of gabbro, an igneous rock. Gabbro is coarse-grained, containing the minerals olivine and plagioclase feldspar

Polished slab of labradorite
Labradorite (calcium sodium aluminum silicate) can seem dull and grey until the light hits correctly, then an array of colours can be observed glowing on the surface

Labradorite C016 / 5698
Labradorite. Close-up of the surface of a rich blue specimen of the mineral labradorite (calcium sodium aluminum silicate)

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

Plagioclase feldspar, a mesmerizing mineral with its captivating colors and unique properties, takes center stage in various geological wonders. In the polarised light microscope image of a thin section of gabbro rock, plagioclase feldspar stands out as vibrant crystals embedded within the dark matrix. Its presence is also evident in the polished slab of labradorite, showcasing its iridescent play-of-color that dazzles the eye. Identified as Labradorite C016 / 5698, this particular specimen exhibits an enchanting blend of blues and greens. The significance extends beyond Earth's boundaries. A microscope image reveals its presence in the Brachina meteorite, emphasizing its cosmic origins and celestial beauty. Back on our planet, labradorite continues to captivate with stunning carvings that showcase its intricate patterns and shimmering hues. Whether it's found in gneiss or gabbro rocks or adorning exquisite jewelry pieces, plagioclase feldspar never fails to leave us awestruck by nature's artistry. The thin sections of gneiss under polarised light microscopy reveal a tapestry-like arrangement where plagioclase feldspar weaves through layers upon layers of other minerals. In every form it takes – be it a microscopic crystal or a grand carving – plagioclase feldspar remains an enduring testament to Earth's geological marvels and serves as a reminder that even amidst vastness or minuteness lies incredible beauty waiting to be discovered.
