Large Apophyllite with Stilbite Specimen — 1.25Kg

A breathtaking display piece, this substantial 1.25Kg specimen showcases glistening Apophyllite crystals rising in sharp, pyramidal points together with soft, peachy-pink Stilbite. The contrast between the glassy clarity of the Apophyllite and the gentle warmth of the Stilbite makes this a truly striking natural sculpture — one that commands attention on any shelf, desk, or altar.

Formed deep within volcanic basalt cavities, Apophyllite and Stilbite frequently occur together in one of nature's most harmonious mineral pairings. At this size and quality, specimens like this are collector-grade.

Physical Properties

  • Apophyllite (Fluorapophyllite) — Chemical Formula: KCa₄(Si₄O₁₀)₂F·8H₂O | Hardness: 4.5–5 (Mohs) | Crystal System: Tetragonal | Lustre: Vitreous to pearly on cleavage faces | Transparency: Transparent to translucent | Colour: Colourless, white, green, or pink depending on trace elements
  • Stilbite (Stilbite-Ca) — Chemical Formula: NaCa₄(Si₁₃Al₅)O₃₆·14H₂O | Hardness: 3.5–4 (Mohs) | Crystal System: Monoclinic | Lustre: Vitreous to pearly | Transparency: Transparent to translucent | Colour: White, peach, pink, orange, or colourless

Geology & Formation

Both minerals belong to the zeolite group (or zeolite-associated minerals) and form as secondary minerals in the cavities and vesicles of basaltic and trappean volcanic rocks. As silica-rich hydrothermal fluids cool and percolate through these voids over millions of years, minerals crystallise slowly — producing the dramatic, well-formed terminations seen on premium specimens. The Deccan Traps of Maharashtra, India are the world's foremost source for this mineral pairing, yielding specimens of exceptional clarity and size.

Crystal Properties

  • Apophyllite — associated with clarity, higher consciousness, and releasing suppressed emotions. A stone of truth and spiritual connection.
  • Stilbite — known for its calming, heart-centred energy, promoting restful sleep, intuition, and inner peace.
