Black Onyx Moon - 4 inch

Black Onyx Moons are carved crescent pieces in deep, uniform black, polished to a smooth and even sheen. The crescent form makes each a clean, elegant display piece, and the dense black colour gives it a striking, minimal presence. This is a substantial moon with real weight in the hand.

Black Onyx is traditionally associated with protection, grounding, and calm steadiness. The moon form suits its grounded character, and it is commonly kept on a shelf or altar, held during meditation focused on stability and boundaries, or displayed as a sleek, protective piece. It makes a striking gift for anyone drawn to bold, dark stones.

Surface sheen and subtle character vary slightly from piece to piece, so each moon carries its own finish.

Geological Information
Onyx is a banded chalcedony variety of quartz (silicon dioxide, Mohs 7, trigonal). Commercial Black Onyx is almost universally produced by dyeing natural grey banded chalcedony to a deep, uniform black, using the sugar-acid or iron nitrate process standardised in the Idar-Oberstein agate trade from the nineteenth century onward; the treatment is stable, permanent, and industry-standard. Onyx has been used since antiquity across Greek, Roman, Mesopotamian, and Egyptian cultures, carved into cameos, intaglios, and amulets, and the black variety has featured in mourning jewellery and protective talismans, making it one of the most continuously used black gemstones in recorded history. It is sourced primarily from Brazil, with material also from India and, historically, Idar-Oberstein, Germany.

AuturaSol Standard
Each natural stone is selected for its authenticity, geological integrity, and energetic clarity. Natural variations in colour, structure, inclusions, and surface features are inherent to geological materials and contribute to the individuality of each piece. Any known treatments, enhancements, stabilization, or man-made characteristics are clearly disclosed within the product information where applicable. Every piece is inspected and photographed to reflect its true character; however, lighting conditions, screen settings, and natural variation may cause slight differences in appearance.
