No garnet has ever come out of Lake Jaco.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe false locality was put about deliberately, to keep competitors away from the real ground while it was being worked. It stuck. Specimens are still circulating today in old collections with Lake Jaco written on the label, and museums and dealers have spent decades untangling it. The actual source is the Sierra de Cruces range in Sierra Mojada municipality, Coahuila, first worked for these in 1994.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eTwo other versions turn up on labels, Sierra de las Cruces and Sierra de la Cruz. Both are wrong. Small errors, but a locality is either right or it is decoration, and a specimen with the wrong ground written on it has lost the only part of its history that cannot be recovered later.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eMineral:\u003c\/strong\u003e \u003cmeta charset=\"utf-8\"\u003eGrossular garnet (Ca₃Al₂(SiO₄)₃), a calcium aluminium silicate\u003cbr\u003e\u003cstrong\u003eCrystal system:\u003c\/strong\u003e \u003cmeta charset=\"utf-8\"\u003eCubic\u003cbr\u003e\u003cstrong\u003eOrigin:\u003c\/strong\u003e \u003cmeta charset=\"utf-8\"\u003eSierra de Cruces, Sierra Mojada Municipality, Coahuila, Mexico\u003cbr\u003e\u003cstrong\u003eHardness:\u003c\/strong\u003e \u003cmeta charset=\"utf-8\"\u003e6.5 to 7 on the Mohs scale; hard, but the crystals are brittle at the edges and chip rather than scratch\u003cbr\u003e\u003cstrong\u003eTreatment:\u003c\/strong\u003e None\u003cbr\u003e\u003cstrong\u003eDimensions:\u003c\/strong\u003e 2.97 x 2.7 x 1.51 cm\u003cbr\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e 11.72 g\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eYou will receive the exact piece photographed.\u003c\/p\u003e","brand":"The Crystal Showroom","offers":[{"title":"Default Title","offer_id":58209108132184,"sku":null,"price":21.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0778\/4880\/5720\/files\/rgg-a-1.jpg?v=1787406485","url":"https:\/\/thecrystalshowroom.com\/products\/grossular-garnet-cluster-a-natural-mexico","provider":"The Crystal Showroom","version":"1.0","type":"link"}
