Banded Onyx Obelisk – Polished 5.75″ Green & Mahogany Calcite

Geological Overview

This striking specimen is sourced from the mineral-rich regions of Pakistan. Known in the trade as "Banded Onyx," it is geologically a sedimentary form of Calcite and Aragonite. These minerals are polymorphs, sharing the same chemistry but differing in crystal structure. The vibrant, "pistachio" green layers are the result of trace magnesium and iron inclusions, while the dark mahogany bands represent concentrated iron oxides and denser aragonite layers deposited in hydrothermal environments.

Aesthetic Appeal

This 5.75-inch obelisk features a masterfully polished visual dichotomy. The upper portion consists of high-clarity, translucent green calcite that exhibits a "jelly-like" depth when backlit. This transitions into a base of opaque, earthy mahogany bands in shades of rust and chocolate. The sharp, geometric lines of the obelisk cut highlight the horizontal bedding planes, creating a sophisticated display piece that bridges the gap between raw geology and modern art.

Metaphysical Properties

A stone of confidence and mental discipline, Pakistani Banded Onyx is highly regarded for its grounding capabilities. The green calcite layers vibrate with the Heart Chakra, encouraging emotional renewal, while the dark mahogany bands connect to the Root Chakra, providing the stability needed to persevere through challenges. It is an exceptional stone for balancing emotional sensitivity with logical action.

Rarity & Collectibility

Graded AA (Premium Collector Grade), this specimen is chosen for its superior translucency and crisp color zoning. The precision of the polish and the lack of significant internal fractures—common in calcite—make this a high-value example for discerning collectors.

Collector’s & Display Notes

• Measurements: 5.75" x 1.25" (14.6 cm x 3.1 cm)
• Origin: Balochistan, Pakistan
• Display Tip: Best displayed with backlighting to highlight the internal "glow" of the green calcite.
• Care: Calcite is a soft mineral (Mohs 3). Clean only with a soft, dry cloth; avoid water or acidic cleaners.

Condition & Authenticity

Transparency Matters: This is a 100% natural specimen with no dyes or chemical enhancements. Consistent with natural cave-growth minerals, minor surface vugs (pits) are present within the mahogany bands; these are authentic geological features and not damage.
