Decorative duo — Banded calcite sphere (onyx marble) and calcite crystal on bases.

A mineral composition resembling a sculpted landscape. This banded calcite sphere, often referred to as marble onyx, reveals a fascinating natural structure, marked by a spectacular central vein reminiscent of a geological fault frozen in stone. Its soft hues—cream, pale green, and ochre—create a rendering that is both organic and contemporary. Every detail seems to sketch an abstract landscape, between mineral layers and natural formations, making the piece particularly expressive and unique. Alongside it, a slightly pink-hued calcite crystal brings light and contrast. Its crystals subtly capture the light, balancing the visual density of the sphere with a more airy presence. The whole is presented on simple bases, highlighting the natural aesthetics of the stones while perfectly integrating into a modern or minimalist interior. Characteristics: Stone 1: Banded calcite (marble onyx) — polished sphere. Stone 2: Natural calcite — crystalline cluster. Presentation: on bases. Approximate dimensions: Sphere: height ~19 cm / diameter ~10.4 cm. Crystal: height ~18 cm / width ~9.5 cm. Each piece is natural and unique, with its variations in colour, texture, and formations. A mineral duo with a strong visual impact, straddling natural sculpture and contemporary decorative object.
