• Weight: 440 g (0.97 lb)
• Source: Argentina
• Polished in: Donghai, China
• Key Features: Vibrant multicolor equatorial band, saturated denim-to-midnight blue tones, natural exposed matrix base, full polish

Introduction:

This 67mm blue onyx sphere is a balanced fusion of contrast and calm. Sourced from Argentina and polished to a mirror gloss in Donghai, it showcases a powerful horizontal band of golden-brown calcite that cuts dramatically through soft blue zoning — reminiscent of planetary rings or a layered canyon wall. Compact and highly displayable, it bridges sculptural elegance with grounding energy.

Geological Details:

While often called “blue onyx,” this stone is geologically banded calcite — a calcium carbonate mineral that forms in layered deposits through sedimentary processes. This sphere exhibits dense zoning with varied mineral inclusions, most notably a bold, uninterrupted iron-rich seam that contrasts strongly with the blue calcite body.

The material originates from Argentina, known for producing richly layered calcite with high saturation and translucency. Its polish, completed in Donghai, reveals the inner structure and color layering with depth and clarity.

Aesthetic Appeal:

Striking yet serene, this sphere carries visual weight. Its multitone band — a blend of ochre, rust, and honey — wraps around the equator, offering strong horizontal balance against the vertically stacked denim-to-steel blue zoning. One hemisphere features a naturally exposed matrix section, adding texture, contrast, and visual grounding.

Thanks to its tight banding and saturated palette, this sphere is well suited for display in curated interiors or as a meditative visual focus. The polished finish gives the surface a glass-like sheen that enhances its planetary feel.

Metaphysical Properties:

Blue banded calcite is associated with emotional harmony, mental clarity, and the throat chakra. It promotes calm communication and self-expression. The presence of warm-toned bands adds an energetic note of grounding and vitality — making this sphere a beautiful balance between the calming and activating forces in crystal healing.

The exposed base can be seen as an energetic anchor — ideal for use in meditative practices, crystal grids, or sacred spaces.

Rarity:

• Vivid equatorial band: Clear, multicolor seam offering strong natural contrast
• Natural & undyed: No artificial enhancements — raw authenticity
• Compact collector size: 67 mm format is display-friendly but rarely this dynamic
• Exposed matrix section: Adds raw character and geologic context

Why You Will Love This:

This piece is small but commanding — a statement sphere that fits comfortably in hand or on a shelf without losing impact. The horizontal seam feels both grounding and cosmic, making it ideal for collectors who value balance in form and meaning. Whether you're a crystal connoisseur, interior designer, or energy worker, this sphere brings color, contrast, and calm to any setting.

Specifications:

• Diameter: 67 mm (2.64 in)
• Weight: 440 g (0.97 lb)
• Finish: Fully polished surface with raw matrix base
• Unique Features: Multicolor horizontal band, rich zoning, natural matrix exposure

Collector's Note:

This is a premium example of Argentina’s banded calcite at its best — naturally bold and beautifully finished. As the market shifts toward smaller, uniform spheres, pieces like this — with distinct seams and organic variation — are becoming increasingly desirable among serious collectors.

Display Recommendations:

• Best shown on a low wood base or crystal ring stand to highlight the banding
• Position with the raw base facing down or slightly angled for contrast
• Excellent paired with smoky quartz, carnelian, or honey calcite for grounding balance
