Feldspar

Feldspar is one of the most abundant mineral groups on Earth; yet, fine crystal specimens are far less common and highly valued by collectors. It occurs in a wide range of forms, from sharp, blocky crystals to beautifully twinned growths, often in association with quartz, mica, and tourmaline. Notable localities include Pakistan and Afghanistan, where impressive crystals are found in alpine-type pegmatites, as well as classic sources in Italy, Russia, and the United States. With their clean crystal forms and elegant associations, feldspar specimens hold a timeless place in fine mineral collections.
