Introduction:

This 63mm blue onyx sphere presents a vivid and moody tapestry of earth-born hues — deep denim, soft slate, and golden caramel veining. Expertly polished in Donghai and cut from natural Argentinian banded calcite, it offers a balanced, medium format ideal for collectors and décor enthusiasts alike.

Geological Details:

Though commonly called “blue onyx,” this mineral is actually banded calcite — a form of calcium carbonate (CaCO₃) that crystallizes in sedimentary layers over millions of years. Iron and other trace minerals contribute to the striking colour contrasts, while fracture-filling minerals give rise to beautiful golden veining patterns unique to each piece.

Aesthetic Appeal:

This sphere features tight, parallel bands of blue-gray and slate, overlaid with rare golden and rust-toned seams. Some faces reveal cloudy translucency, while others highlight rhythmic layering and natural flow lines. It holds presence both in the hand and on display.

Metaphysical Properties:

• Blue Calcite – Calming, supportive of emotional clarity and communication
• Golden Veins – Believed to amplify grounding energy and spiritual insight

This sphere is often used in throat chakra work and general energetic cleansing. Its size and energy make it ideal for home altars, meditation setups, or workspaces.

Specifications:

• Diameter: 63 mm (2.48 in)
• Weight: 355 g (0.78 lb)
• Finish: Gloss polished
• Unique Features: Natural golden banding, soft blue gradient, no dyes or treatments

Collector's Note:

This is a well-balanced example of mid-size blue onyx, with clean polish, excellent colour zoning, and rare golden inclusions. Pieces with this balance of translucency, banding, and polish are becoming increasingly hard to find — especially undyed and naturally formed.
