Introduction:

This 60mm Blue Onyx sphere is a refined example of natural banded calcite, featuring rich slate-to-sky blue banding with fine golden seams from iron oxide inclusions. Its small size and weight make it an accessible piece for new collectors, while its color complexity and polish quality ensure it appeals to seasoned buyers as well.

Geological Details:

Despite the name "Blue Onyx," this stone is actually a form of banded calcite — a calcium carbonate mineral formed through rhythmic sedimentary layering over time. Sourced from the mineral-rich region of Balochistan, Pakistan, the material is known for its natural color and stability.

This specimen was polished in Donghai, China, enhancing the internal zoning and giving it a consistent roundness and surface gloss. Iron-rich veins add a striking, earthy contrast to the tranquil blue tones.

Aesthetic Appeal:

Sphere H presents beautiful, evenly spaced horizontal bands with subtle transitions between blue, white, gray, and warm brown. One face shows a visually interesting iron-cross seam structure, while another reveals translucent zones with subtle clouding.

Its form is smooth and symmetrical, polished to a satin gloss that gently reflects light without overwhelming the internal texture.

Metaphysical Properties:

Associated with the throat chakra, banded blue calcite is valued for promoting calm, clarity, and communication. The golden iron veining offers grounding energy tied to the solar plexus, making this piece balanced and centering for meditation, journaling, or emotional reset practices.
