Beschreibung

Locality: Pune District, Maharashtra, India

Metric: Height 39 to 40 cm · Width 56 to 61 cm · Depth ?

Imperial: Height 15.4 to 15.7 in · Width 22.0 to 24.0 in · Depth ?

This one-of-a-kind specimen from Pune is a broad plate carpeted in peach stilbite, its small bladed crystals packed together into a soft, sugary surface. Scattered across it sit glassy clusters of pale mint-green apophyllite, their blocky, stepped crystals catching the light like little stacks of ice cubes, with one deeper green rosette standing out near the edge. The dark basalt shows along the back and sides, framing the colour on the front, and the whole piece has real presence as a centrepiece.

Both minerals grew inside gas pockets in the ancient lava flows of the Deccan Traps, where warm, mineral-rich water slowly seeped through the basalt and deposited crystals along the cavity walls. The quarries around Pune are known worldwide for apophyllite and stilbite, and green apophyllite resting on peach stilbite is one of the classic combinations from the region.

Stilbite is fairly soft, at about 3.5 to 4 on the Mohs scale, and apophyllite is 4.5 to 5 and cleaves easily, so handle this piece by its base, keep it away from knocks and dust it with a soft brush rather than washing it.

Chemical Composition: Fluorapophyllite, KCa₄Si₈O₂₀(F,OH)·8H₂O, on stilbite, NaCa₂Al₅Si₁₃O₃₆·14H₂O

Mohs Hardness: 3.5–5
