The image is a detailed, vintage illustration of an agate stone displayed on a rectangular base. The agate is the focal point, depicted as an oval with intricate banding patterns. The bands are a mix of creamy white, warm brown, and deep indigo, creating a layered, almost wood-grain effect. The agate appears to have been cut and polished to reveal these internal patterns. The agate rests on a rectangular base that is textured with a sponge-like pattern. The base is a mix of light and dark brown, giving it a rough, natural appearance. The illustration is done in a style reminiscent of botanical or geological drawings, with precise lines and delicate shading. A number '412' is visible in the upper right corner, likely a catalog or reference number. The illustration is signed in the lower right corner with the text 'drawn and published by F.S. Buckley, London'. The overall impression is one of scientific accuracy combined with artistic skill, typical of illustrations from the 19th or early 20th century.
