{"title":"Faden Quartz","description":"\u003cp\u003e\u003cstrong\u003eFaden Quartz\u003c\/strong\u003e is a rare growth variety of \u003cstrong\u003equartz\u003c\/strong\u003e (SiO2) instantly recognizable by the thin, white, thread-like line — the \"faden\" (German for thread) — that runs through the length of an otherwise transparent crystal. This feature forms when a crystal growing inside a slowly widening fissure repeatedly fractures and heals as the host rock pulls apart, leaving behind a scar of fluid inclusions that traces the entire history of the opening fracture.\u003c\/p\u003e\u003cp\u003eThe classic source is the \u003cstrong\u003eAlps\u003c\/strong\u003e, particularly historic Alpine cleft localities such as \u003cstrong\u003eLa Table\u003c\/strong\u003e in Savoie, France, and Swiss finds often associated with \u003cstrong\u003eGwindel quartz\u003c\/strong\u003e. Today the finest and most abundant material comes from \u003cstrong\u003eSouth Waziristan\u003c\/strong\u003e and the \u003cstrong\u003eDera Ismail Khan District\u003c\/strong\u003e in \u003cstrong\u003eKhyber Pakhtunkhwa, Pakistan\u003c\/strong\u003e, where water-clear, doubly terminated crystals — sometimes stacked into dramatic towers or paired with \u003cstrong\u003ebrookite\u003c\/strong\u003e and \u003cstrong\u003echlorite\u003c\/strong\u003e inclusions — are prized by collectors worldwide. Other notable occurrences include the \u003cstrong\u003eBig Bertha Mine\u003c\/strong\u003e in \u003cstrong\u003eLa Paz County, Arizona\u003c\/strong\u003e.\u003c\/p\u003e\u003cp\u003eCollectors seek Faden Quartz for its sculptural, almost architectural habit: flattened, tabular or platy crystals bridging the gap where a fracture once opened, each one a frozen record of tectonic movement. Fine specimens combine gemmy transparency, sharp terminations, and a bold, unbroken faden line, making this one of the most geologically fascinating and visually striking quartz varieties in any mineral collection.\u003c\/p\u003e","products":[{"product_id":"lz-faden-quartz-switzerland-0","title":"FADEN QUARTZ – Alpine Transparent Scepter Crystal from Switzerland","description":"\u003cp\u003eNatural Faden Quartz crystal from the Bedretto Valley, Leventina, Ticino, Switzerland.
