Peach Moonstone Sphere — Layered Feldspar with Strong Adularescence + Structural Zoning

Peach Moonstone Sphere — Layered Feldspar with Strong Adularescence + Structural Zoning

A high-structure peach moonstone sphere showing well-defined internal layering, mineral zoning, and a more pronounced silvery adularescent sheen across the central band.

This piece is a great example of how moonstone actually forms — built from intergrown feldspar layers, rather than a single uniform crystal. The horizontal banding and plate-like textures you can see are natural growth features, while the internal veils and micro-fractures show its geological history under pressure.

When rotated in light, you’ll notice a soft reflective glow (adularescence) moving across the surface — caused by light scattering between microscopic feldspar layers.

🔍 Key Features

📍 Strong horizontal feldspar layering

📍 Noticeable central sheen (adularescence band)

📍 Internal veils and mineral zoning

📍 Natural fracture lines and structural texture

📍 Warm peach to caramel colour variation

📍 Polished sphere enhancing internal optical effects

📏 Dimensions

Diameter: 5.1 cm

Weight: 203 grams

🧪 Geological & Scientific Notes

Mineral Group: Feldspar (Orthoclase / Albite intergrowth)

Variety: Moonstone

Chemical Composition: KAlSi₃O₈ (Orthoclase dominant)

Crystal System: Monoclinic

Mohs Hardness: 6 – 6.5

Lustre: Vitreous to pearly

Transparency: Translucent to opaque

Optical Effect: Adularescence

The visible sheen in this piece is stronger than average for peach moonstone and is produced by light interference between internal feldspar layers, not surface polish.

The internal lines and slight fractures are natural and reflect cooling, pressure, and mineral growth over time.

🧼 Care

Avoid knocks or drops (natural cleavage planes present)

Keep away from prolonged water exposure

Clean with a soft dry cloth

Store separately to prevent scratching

💡 Why This Piece Stands Out

Compared to your previous sphere, this one leans more into:

✔ Cleaner structure with less chaotic fracturing

✔ More visible sheen (this is your selling point)

✔ Strong banding that shows feldspar layering clearly

This makes it a better “visual + optical effect” piece, rather than a fracture story piece.
