Description from the seller
Imposing Sphere in Mexican Onyx Finely Polished, WER-979 — This specimen consists of a splendid sphere made of Mexican onyx, a mineral that, despite its common name, is actually a variety of banded Calcite (calcium carbonate, CaCO3). It forms in karst environments, where mineral-rich waters deposit successive layers of carbonate. Its compact microcrystalline structure and well-defined bands make it ideal for sculptural work and mirror polishing. Visual analysis of this sphere reveals a complex and fascinating polychromy. The predominant tones are pale green and aquamarine, interspersed with bands rich in iron oxides that confer accents of rust red, burnt orange, and brown. These color variations are the result of mineral inclusions, mainly serpentine and iron oxides, incorporated into the different calcite layers during its slow formation. Transparency is variable, with semi-translucent zones that allow delicate light diffusion through the bands. The origin of this material is Mexico, a region famous for its high-quality marble-onyx deposits. Here, karst geological formations allowed the deposition of calcite layers with mineral inclusions that determine the distinctive coloration. The age of formation may date back millions of years, testament to geological processes spanning geologic eras. The sphere working highlights the intrinsic beauty of the mineral in an exceptional way. The mirror polishing enhances not only the vibrant colors but also the depth and three-dimensionality of the bands, creating a hypnotic effect that invites close observation. Each cross-section of the bands reveals a unique pattern, making the sphere a piece of natural art. The condition of the specimen is excellent, free of fractures or significant abrasions, a testament to the care in workmanship and preservation. Structural integrity and surface finish help maintain its aesthetic and collecting value. The sphere is ready to be displayed on any stand that enhances its shape and colors.
Seller's Story
The Mineral Art Gallery offers minerals, fossils, shells and natural elements.
Born in Italy in 2017, today she collaborates with international galleries and collectors, she is a direct importer of large minerals and naturalistic collectible elements; deals with the processing to insert them inside the living space. A section of the gallery was dedicated to the Wunderkammer, "chamber of wonders or cabinet of curiosities" in which Mirabilia elements are presented: naturalia and italiania, a union between "the present is the past".
