Onyx Artifact Appraisal

Banded Onyx or Marble Pyramid

The item is a small, polished pyramid-shaped decorative object, likely intended for display or as a paperweight. It is crafted from a type of banded stone, most likely Onyx or a similar variegated marble, exhibiting distinct layers of color. The primary colors visible are shades of cream, light green, and white, interspersed with prominent veins and streaks of earthy brown, russet, and darker amber tones. These darker inclusions appear to run vertically from the base towards the apex, creating a natural focal point. The surface of the pyramid appears to be smooth and highly polished, reflecting ambient light, which suggests good craftsmanship in its finishing. The form is a classic four-sided pyramid with a square base, tapering symmetrically to a sharp point at the top. The edges appear crisp and well-defined, indicating precision in cutting and shaping. There are no readily visible chips, cracks, or significant abrasions on the polished surfaces, suggesting the item is in good to excellent condition. The natural banding and coloration of the stone are its most distinguishing features, making each piece unique. Given the material and common decorative trends, this item likely dates from the late 20th or early 21st century. No manufacturing marks or signatures are discernible from the provided images. Its relatively small size, judging by its appearance on a table surface, positions it as a desk accessory or shelf adornment.
