In the older days, in the1970s-early 1980s when this material was first starting to come out in quantity, there was a unique style found at the Pashan Hills quarry which had these rows of sharp, mint-colored crystals standing upright on white stilbite. To this day, the style remains unique to that era. They are more minty-colored, more sparkly and lustrous, and I love the geometry of the \"hedgerows\" standing upon rolling hills of stilbite-coated basalt matrix. This is a combination immediately recognizable. With long hedgerows on a huge matrix, almost no damage, and sharp crystals to 3 cm, this stands as a superior example of the find. Ex.

That party trick is the entire reason for its name.\n\nIn 1806 the French mineralogist René Just Haüy named the broader family **apophyllite**. He built the word from two Greek roots: **apo**, \"off\", and **phyllon**, \"leaf\"[1]. The name describes what happens when the crystal is heated. Water locked inside the structure escapes, and the mineral flakes apart along flat parallel sheets. A later Greek-derived form, *apophyllízo*, glosses the same idea — \"it flakes off\"[2].\n\nFor most of the 19th and 20th centuries \"apophyllite\" referred to a single species. That changed once chemical analyses revealed real variation inside the structure. Two sites in the crystal proved swappable: potassium against sodium in one, fluorine against hydroxide in the other. In 1978 the American mineralogists Pete J. Dunn, Roland C. Rouse, and Julie A. Norberg formally recognised those variants. They proposed splitting apophyllite into a group of related species[3].\n\nA nomenclature revision approved by the International Mineralogical Association in 2013 finalised the split. The old name was retired, and each end-member received its own species name with prefixes and suffixes describing its dominant chemistry[4]. Fluorapophyllite-(K) — fluorine-dominant in one site, potassium-dominant in the other — is the most common of those end-members. Most specimens once labelled simply \"apophyllite\" turn out, on analysis, to be this one.","claude-opus-4-7","1.7.0",{"markdown":405,"model_version":402,"prompt_version":403,"reviewed_at":11},"Fluorapophyllite-(K) has no industrial role. The mineral is too soft, too scattered, and too rare in concentrated deposits to interest any commodity producer. Its demand sits entirely with collectors and with the geologists who read it as a marker of basalt alteration.\n\nThe collector market is the larger of the two. The mineral forms large, well-developed crystals in many colours, and that combination is unusually photogenic for a non-gem species[1]. The most wanted variation is the green one. It comes from the Deccan Traps of western India — the immense flood-basalt province that covers much of Maharashtra[2]. Other prized localities include the Harz Mountains of Germany, Mont Saint-Hilaire in Canada, and Kongsberg in Norway[2]. Classic specimens also come from Trentino in Italy, Belfast in Northern Ireland, the Faroe Islands, Kimberley in South Africa, and Guanajuato in Mexico[3].\n\nFor the field geologist, the mineral has a quieter but more practical use. It grows as a secondary mineral inside the gas bubbles — the vesicles — left in cooling basalt and other volcanic rocks[1]. It is also structurally related to the zeolites, a family of porous aluminosilicate minerals that trap and release water[3]. It tends to crystallise alongside them when warm groundwater circulates through the rock long after eruption. Finding it inside a vesicle is, in practice, a sign that the host basalt has been through that low-temperature alteration history."]
