{"title":"Aragonite","description":"\u003cp\u003e\u003cstrong\u003eAragonite\u003c\/strong\u003e is a calcium carbonate mineral (CaCO3) and the orthorhombic \u003cstrong\u003epolymorph of calcite\u003c\/strong\u003e, forming distinctive tabular, needle-like, or pseudohexagonal twinned crystals rather than calcite's classic rhombohedra. Its multiple twinning by the {110} planes produces the pseudohexagonal \"trilling\" prisms that make aragonite so recognizable, while a separate branching habit known as \u003cstrong\u003eflos ferri\u003c\/strong\u003e (\"flowers of iron\") forms delicate coral-like or tree-like sprays.\u003c\/p\u003e\u003cp\u003eThe mineral's name comes from its type locality of \u003cstrong\u003eMolina de Aragón\u003c\/strong\u003e in Guadalajara, Spain, where lustrous doubly-terminated twins are still found today, alongside similar material from \u003cstrong\u003eEnguídanos\u003c\/strong\u003e and \u003cstrong\u003eMinglanilla\u003c\/strong\u003e.

Today, however, the market is dominated by exceptional pseudohexagonal clusters from \u003cstrong\u003eTazouta\u003c\/strong\u003e, near Sefrou in Morocco's Middle Atlas Mountains, prized for their orange-red color, sharp terminations, and abundance, alongside striking fluorescent stalactites from \u003cstrong\u003eOujda\u003c\/strong\u003e.\u003c\/p\u003e\u003cp\u003eCollectors seek aragonite for its elegant twinning, wide color range from colorless and white to green, blue, and purple, and its close relationship to biogenic carbonate found in mollusk shells, coral, and pearls. Fine, undamaged twinned specimens and flos ferri sprays remain especially desirable for both mineral and crystallography collections.\u003c\/p\u003e","products":[{"product_id":"lz-aragonite-svizzera-0","title":"ARAGONITE – Botryoidal Alpine White mineral from Switzerland – New Find","description":"\u003cp\u003eRare alpine Aragonite specimen from the Lucomagno Gorge, Grisons, Switzerland.
