There’s some cloudiness within the phantoming, but it appears more as soft, wispy internal veils rather than dense opaque zones, so the colour still has plenty of depth.\u003c\/p\u003e\n\u003cp\u003eThere’s a little natural etching around the termination and upper part of the crystal, creating an interesting surface texture. At the base the crystal appears to be partially double terminated, with the very early beginnings of a bowtie formation starting to develop. In this habit, parallel crystals begin growing in opposing directions through a narrower central point, although here it’s only just starting to form.\u003c\/p\u003e\n\u003cp\u003eGuerrero amethyst is one of the great classic amethyst localities, and one of the most distinctive expressions of amethyst there is. \u003cspan\u003eWhen we talk about a “classic” locality in the mineral world, we refer to specimens that have a long history, are instantly recognisable and have distinctive aesthetic, and \u003cmeta charset=\"utf-8\"\u003e\u003c\/span\u003e\u003cspan\u003ematerial that collectors have actively sought out for a long time. \u003cmeta charset=\"utf-8\"\u003e\u003c\/span\u003e\u003cspan\u003eOther examples include amethyst from Goboboseb in Namibia, Veracruz in Mexico, Thunder Bay in Canada and Four Peaks in Arizona, \u003cmeta charset=\"utf-8\"\u003e\u003c\/span\u003e\u003cspan\u003ewhich are all highly collectible and recognisable in their own right.\u003c\/span\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-pm-slice=\"1 1 []\"\u003e\u003cspan\u003eGuerrero has a distinctive habit. The crystals form as long, tapered points that feature rich, concentrated colour that can form in concentrated phantoms, even when crystals feature strong transparency. \u003c\/span\u003e\u003cspan\u003eThey also frequently feature parallel growth, giving them a very recognisable silhouette and adding extra detail to appreciate.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-pm-slice=\"1 1 []\"\u003e\u003cspan\u003eThe history of Guerrero amethyst is fascinating. Mining was most active throughout the 1970s, 80s and 90s, there's never really been a single mine. The amethyst occurs throughout a large area around Amatitlán, where multiple small veins and pockets were worked through shallow cuts and hand dug workings. Miners would follow one vein until it stopped producing, then move on to search for another pocket.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThat also means Guerrero crystals aren't strictly uniform, and there are beautiful variation of colour, zoning, transparency and crystal form.\u003c\/span\u003e\u003cspan\u003e Material from one pocket can be rather different from another, while still being unmistakably Guerrero.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eBy the early 2000s material became much harder to access, and mining in Guerrero has also been heavily affected by cartel activity and the increasing danger of working in the region. That combination has made good old Guerrero material increasingly difficult to source today.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eThis particular parcel has its own wonderful history. The specimens had been sitting untouched in a garage for close to 50 years and were offered to us still containing the original dirt and clay from mining. We received them exactly like that and have cleaned every piece ourselves.\u003c\/p\u003e\n\u003cp\u003eIt’s incredibly exciting to be able to offer genuine old Guerrero amethyst in smaller, accessible specimens. These have all the history and locality character that make Guerrero so desirable, without the price tags attached to the large museum scale examples for which the locality is famous.\u003c\/p\u003e","brand":"The Liminal Stone","offers":[{"title":"Default Title","offer_id":67582298652804,"sku":"I-84","price":255.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1020\/1815\/4628\/files\/D8FD051A-3834-40AC-9A47-367408C21592.jpg?v=1790743480","url":"https:\/\/www.theliminalstone.com\/products\/84-amethyst-guerrero-mexico","provider":"The Liminal Stone","version":"1.0","type":"link"}
