Introduction:

This 70mm blue calcite sphere is a stunning blend of deep sky tones and golden inclusions, delivering both visual impact and grounding energy. Polished in Donghai from premium material sourced in Argentina, this piece features dramatic banding intersected by golden iron veining, with a partially raw base offering an authentic, geological window into its formation.

Its compact size and rich coloration make it ideal for collectors, energy practitioners, and design lovers alike.

Geological Details:

Though often called “blue onyx,” this specimen is banded calcite — a sedimentary calcium carbonate mineral belonging to the trigonal crystal system. It forms through mineral-rich water percolation in caves or fractures, laying down rhythmic bands of calcite over time.

The visible golden seams are caused by iron oxide inclusions that formed naturally along stress lines or fractures, resulting in a unique crosshatch pattern across the sphere's surface. The polished hemisphere reveals internal zoning and subtle translucency, while the raw base retains its natural texture.

Aesthetic Appeal:

This sphere combines the sophistication of deep slate-blue and navy calcite layers with the raw intensity of rust-hued veining. Its coloration evokes celestial imagery — like a distant stormy planet marked by golden lightning.

The exposed base offers contrast and a reminder of its natural origins, creating a piece that is both sculptural and scientifically intriguing.

Metaphysical Properties:

Blue calcite is known for its calming, communicative energy and its resonance with the throat chakra. It encourages clear self-expression, inner peace, and emotional clarity. The presence of raw stone on one side enhances its grounding properties, helping users anchor their thoughts and intentions.

The golden veining may be associated with solar energy or the solar plexus chakra, bringing warmth and confidence into the energetic field.

Rarity:

• Natural undyed material from Argentina
• Rare iron oxide veining intersecting blue banding
• Mixed-finish format with raw and polished sides
• High luster and balanced polish achieved in Donghai

Why You Will Love This:

This sphere feels both ancient and refined — ideal for collectors seeking authenticity with style. The unique vein patterns ensure no two are alike, and the visual weight of the darker tones pairs beautifully with natural woods, metals, or minimalist décor.

Whether it sits on a meditation altar or a bookshelf, it commands attention and invites contemplation.

Specifications:

• Diameter: 70 mm (2.75 inches)
• Weight: 500 g (1.10 lb)
• Finish: Polished upper hemisphere with natural raw base
• Unique Features: Golden veining across blue calcite banding, one-sided matrix exposure, rich color zoning

Collector’s Note:

Argentinian blue calcite is gaining popularity for its richness and structure. This piece’s intersecting iron seams and exposed raw base create a balanced presentation of both natural origin and lapidary craftsmanship. As global demand increases, mixed-finish spheres of this quality are becoming harder to source.

Display Recommendations:

• Place on a low-profile wooden stand to display raw base downward
• Best lit under natural sunlight or warm LED to enhance its golden seam and blue depth
• Pairs well with hematite, citrine, or labradorite for contrast in tone and energy
