{"title":"Red Jasper","description":"\u003cp\u003e\u003cstrong\u003eRed Jasper\u003c\/strong\u003e is an opaque, microcrystalline variety of \u003cstrong\u003equartz\u003c\/strong\u003e belonging to the \u003cstrong\u003echalcedony group\u003c\/strong\u003e, prized for its deep brick-red to wine-red color. Red Jasper is an opaque variety of the mineral chalcedony, which is itself a microcrystalline variety of quartz, characterized by its deep red color, which is derived from inclusions of iron oxides, particularly hematite. Chemically it is essentially \u003cstrong\u003esilicon dioxide\u003c\/strong\u003e (SiO2), and inclusions of iron oxide (Fe2O3) in the form of hematite or goethite contribute to its vibrant red color. It typically forms in massive or botryoidal aggregates rather than well-formed crystals, and is typically associated with banded iron formations, though it also occurs filling cavities and veins in volcanic rocks and as cement in sedimentary breccias.\u003c\/p\u003e\u003cp\u003eClassic and economically important occurrences span several continents. Russia has significant deposits, particularly in the Ural Mountains and the Altai Republic, with the \u003cstrong\u003eOrsk\u003c\/strong\u003e district of the Southern Urals especially famous — locally the material is known as \u003cstrong\u003eOrsk Jasper\u003c\/strong\u003e. Brazil is one of the most significant sources of high-quality red jasper, with deposits found in Minas Gerais, Rio Grande do Sul, and Bahia, while India is another major source, with major deposits in Rajasthan, Gujarat, and Madhya Pradesh. In the \u003cstrong\u003eUnited States\u003c\/strong\u003e, notable localities include \u003cstrong\u003eArizona\u003c\/strong\u003e (Gila County and the Jakes Corner area), \u003cstrong\u003eOregon\u003c\/strong\u003e, \u003cstrong\u003eCalifornia\u003c\/strong\u003e's Mojave Desert, and Vermont's historic \u003cstrong\u003eParrot Jasper Mine\u003c\/strong\u003e. \u003cstrong\u003eWestern Australia\u003c\/strong\u003e's Three Corner Conglomerate at Rocklea Station yields striking banded red jasper intergrown with hematite, and \u003cstrong\u003eMadagascar\u003c\/strong\u003e contributes polychrome and orbicular varieties from mines near its northwest coast. Specimens are also documented from Chubut Province in Argentina, the Czech Republic's Holoubkov and Radostná pod Kozákovem localities, and Hungary.\u003c\/p\u003e\u003cp\u003eCollectors value Red Jasper for its combination of durability, rich uniform coloration, and deep archaeological pedigree — Red Jasper was used in tools, seals, beads, and decorative objects across many ancient civilisations, including Mesopotamia, Egypt, and parts of the Mediterranean, with cylinder seals in Mesopotamia rolled across wet clay to leave a detailed impression, acting as an early form of signature. With a hardness around 7 on the Mohs scale and a fine, glassy-to-waxy luster, it takes an excellent polish and displays natural banding, brecciation, and occasional hematite streaking that make each specimen unique. Related jasper varieties collectors often pair with Red Jasper include Bloodstone, Mookaite, Picture Jasper, and Ocean Jasper, all sharing the same silica-rich, iron-colored heritage that makes this species a cornerstone of any mineral collection.\u003c\/p\u003e","products":[],"url":"https:\/\/www.italmineral.com\/collections\/red-jasper.oembed","provider":"ITALMINERAL","version":"1.0","type":"link"}
