Rhodochrosite Slab – Capillitas Argentina | Polished Collector Specimen

A large, double-sided polished rhodochrosite slab from the Capillitas Mining District, Catamarca Province, Argentina — one of the world's most important localities for banded rhodochrosite. Weighing 1.357kg including the stand and standing approximately 320mm tall as displayed, this is a substantial collector-grade specimen with immediate visual presence.

The polished surface reveals hundreds of fine mineral layers in flowing, lace-like formations: intense rose and raspberry pink, soft blush and cream, burgundy accent lines, and intricate concentric wave-like patterns. Natural cavities and colour-zoning variations are preserved throughout, giving the slab a landscape-like depth when viewed closely.

What Is Rhodochrosite?

Rhodochrosite is a manganese carbonate mineral (MnCO₃) that forms in hydrothermal veins and sedimentary deposits. Its characteristic pink-to-red colour is caused by manganese content, with paler cream and beige bands representing zones of lower manganese concentration or intergrown calcite. The Capillitas deposit in Argentina is globally recognised for producing rhodochrosite with exceptionally fine, complex banding — a result of slow, rhythmic mineral precipitation over millions of years. Argentine rhodochrosite from Capillitas is considered among the finest in the world for collector-quality polished slabs.

Polished on Both Sides

Both faces of this slab have been polished, revealing a different cross-section of the mineral's internal formation on each side. Natural outer edges and small cavities have been retained where present, creating contrast between the polished mineral surface and its original geological structure. The specimen can be displayed from either face.

Ideal For

• Rhodochrosite and Argentine mineral collectors
• Mineral cabinets and display shelves
• Statement home and interior décor
• Geology and lapidary enthusiasts
• Significant one-of-a-kind gifts
• Offices and creative studios

Display & Care

Display on a strong, flat, stable surface using the included metal stand. Rhodochrosite has a Mohs hardness of 3.5–4 — softer than quartz — and should be handled with care. Support the stone and stand securely when moving. Dust gently with a soft, clean cloth or brush. Avoid impacts, abrasive cleaners, prolonged soaking, and harsh chemical products.

This is a unique natural specimen sold exactly as shown. Natural cavities, colour zoning, inclusions, minor fractures, and banding variations are inherent characteristics of natural stone. Please examine all photographs carefully before purchasing. Only one available.
