African Turquoise Disc with Central Square Cutout and Carved Symbols

This appears to be a disc-shaped art object, possibly a decorative piece, made from a material resembling African turquoise. Its diameter is approximately 3-4 inches, though precise measurements are not available. The material exhibits a striking blue-green color, characteristic of turquoise, with dark brown or black matrix veining, giving it a mottled and organic appearance. The surface is not smooth; it has an undulating, somewhat rough texture, indicating either natural formation or deliberate artistic distressing. A distinctive square hole is cut through the center of the disc. The surface also features incised or carved markings that resemble ancient Chinese characters or symbols, arranged around the central square opening. These markings are not perfectly sharp but are somewhat softened, possibly due to wear, the nature of the material, or the artistic rendering. The overall condition shows a natural patina with variations in color saturation and surface texture across the disc. There are no obvious signs of significant damage, repairs, or heavy wear beyond what appears to be intentional or inherent to the material's properties. The craftsmanship suggests a focus on the natural beauty of the stone, with the carvings adding an historical or cultural reference. The piece seems to embody an antique or tribal aesthetic, though it could be a modern piece designed to replicate such a look. The 'African turquoise' context provided further supports the material identification, which is not a true turquoise but a form of mottled jasper or chert, often treated and dyed.
