Geological Details:

This specimen is composed of banded calcite, a calcium carbonate mineral with a trigonal crystal system. It is often misnamed “blue onyx” in trade. The soothing blue and white coloration results from rhythmic deposition of mineral-rich waters, with subtle iron and trace mineral inclusions adding delicate contrast and depth.

Argentinian blue calcite is recognized for its soft translucency and pastel color palette. The polish performed in Donghai enhances the material’s inherent glow, revealing fluid zoning and painterly internal banding.

Aesthetic Appeal:

This sphere’s banding transitions between denim blue, slate, and soft celestite tones, arranged in tight, fluid layers. The zoning feels natural and serene — like wisps of cloud passing over a tranquil sea.

The polish is even and soft-glossed, enhancing the internal movement without creating harsh reflections. Its subtle elegance and layered gradients make it perfect for minimalist décor, spiritual work, or gifting.

Metaphysical Properties:

Banded blue calcite is widely associated with calming, cleansing, and throat chakra alignment. It is known to support clear communication and emotional regulation, helping release tension and encourage heartfelt expression.

This sphere's gentle energy and compact form make it a perfect companion for desk spaces, altars, or personal meditation areas — anchoring calmness in both emotional and physical environments.
