{"title":"Rutile","description":"\u003cp\u003e\u003cstrong\u003eRutile\u003c\/strong\u003e is one of the natural polymorphs of \u003cstrong\u003etitanium dioxide\u003c\/strong\u003e (TiO2), and by far the most common of the group, which also includes anatase and brookite. It forms slender, striated, tetragonal prisms in colors ranging from deep blood-red and reddish-brown to metallic black, prized for an exceptionally high refractive index and adamantine luster. Elbow-shaped and cyclic twins — sixlings and eightlings — are a signature feature of the species, and needle-like inclusions in quartz produce the famous gem material known as rutilated quartz.\u003c\/p\u003e\u003cp\u003eClassic type material comes from Horcajuelo de la Sierra in Spain, but collectors prize crystals from a handful of truly exceptional deposits. \u003cstrong\u003eGraves Mountain\u003c\/strong\u003e, Georgia, USA, has produced the finest mirror-like, stubby crystals ever found, alongside historic American localities like \u003cstrong\u003eMagnet Cove\u003c\/strong\u003e, Arkansas, \u003cstrong\u003eParkesburg\u003c\/strong\u003e, Pennsylvania, and the \u003cstrong\u003eChampion Mine\u003c\/strong\u003e in California. Brazil supplies extraordinary golden acicular sprays and twins from \u003cstrong\u003eNovo Horizonte\u003c\/strong\u003e and \u003cstrong\u003eDiamantina\u003c\/strong\u003e, while alpine clefts of the \u003cstrong\u003eBinn Valley\u003c\/strong\u003e, \u003cstrong\u003eSt. Gotthard\u003c\/strong\u003e, and \u003cstrong\u003eCavradi gorge\u003c\/strong\u003e in Switzerland yield brilliant striated crystals often in epitaxy on hematite. Niobium- and tantalum-rich varieties, \u003cstrong\u003eilmenorutile\u003c\/strong\u003e and \u003cstrong\u003estrüverite\u003c\/strong\u003e, occur in the pegmatites of Madagascar and Mozambique.\u003c\/p\u003e\u003cp\u003eBeyond its role as a major titanium ore, rutile is a true connoisseur's mineral: sought for its striking twin geometry, saturated color, and metallic sheen, and treasured whenever paired with kyanite, hematite, or quartz matrix. Fine, well-formed rutile specimens remain relatively scarce on the market, making sharp, lustrous crystals from these historic localities especially desirable for serious 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.
