{"title":"Anatase","description":"\u003cp\u003e\u003cstrong\u003eAnatase\u003c\/strong\u003e is one of the three natural polymorphs of \u003cstrong\u003etitanium dioxide (TiO₂)\u003c\/strong\u003e, alongside \u003cstrong\u003erutile\u003c\/strong\u003e and \u003cstrong\u003ebrookite\u003c\/strong\u003e. Named from the Greek for \"extension\" in reference to its elongated tetragonal dipyramids, it typically forms sharp, lustrous, adamantine crystals ranging from pale yellow and honey-brown to deep indigo-blue and near-black, often with striking metallic iridescence. Crystals commonly grow as simple or twinned bipyramids, sometimes flattened into tabular habits, on quartz or in association with \u003cstrong\u003ealbite\u003c\/strong\u003e, \u003cstrong\u003echlorite\u003c\/strong\u003e, and \u003cstrong\u003eepidote\u003c\/strong\u003e.\u003c\/p\u003e\u003cp\u003eThe classic type locality material comes from Alpine-cleft fissures in the \u003cstrong\u003eBourg d'Oisans\u003c\/strong\u003e and \u003cstrong\u003eLe Freney-d'Oisans\u003c\/strong\u003e district of the French Alps, where lustrous black and blue-black bipyramids are prized among collectors of European alpine minerals. Fine specimens also come from \u003cstrong\u003eBinn Valley\u003c\/strong\u003e in Switzerland, \u003cstrong\u003eCavradi\u003c\/strong\u003e in Graubünden, and numerous alpine-vein localities across the Swiss, Italian, and Tirolian Alps. Norway contributes notable crystals from \u003cstrong\u003eHardangervidda\u003c\/strong\u003e and the \u003cstrong\u003eKragerø\u003c\/strong\u003e district, while large, well-formed anatase crystals from \u003cstrong\u003eDiamantina, Minas Gerais\u003c\/strong\u003e in Brazil rank among the finest and largest ever found, some reaching several centimeters and showing exceptional gemmy transparency.\u003c\/p\u003e\u003cp\u003eCollectors seek anatase for its rare crystal habit among oxide minerals, its color-zoning and pleochroism, and its scientific importance as a widespread accessory mineral in metamorphic and hydrothermal veins. Well-terminated, gemmy crystals — particularly the deep blue Brazilian specimens and the classic black French alpine-cleft bipyramids — are considered prime pieces for both systematic and aesthetic mineral collections.\u003c\/p\u003e","products":[{"product_id":"anatase-truncated-bipyramidal-crystals-with-high-luster-on-matrix-pakistan","title":"ANATASE – Truncated Bipyramidal Crystals with High Luster on Matrix, Pakistan","description":"\u003cp\u003eNatural Anatase from Kharan District, Balochistan, Pakistan.
