Jasper is a cryptocrystalline form of quartz, typically opaque with a rich range of earthy colors that stem from iron oxides and other impurities. It commonly forms massive aggregates with a waxy to dull luster and a conchoidal fracture, presenting as dense, uniform nodules rather than transparent crystals.

About Jasper
Notable specimens come from a variety of classic localities around the world, including regions in the United States, Mexico, and China, where jasper can be found in nodular deposits and as replacement layers in host rocks. Collectors prize its steady color bands and opaque character, which render it ideal for cabinet displays and rough-cut specimens alike, as well as for use in decorative carvings and cabochons where texture and tone are foregrounded. Its durability and varied morphology make it a staple for educational displays that illustrate color contrasts and material identity within the quartz family.
