Abalone Inlay Decor Appraisal

Aztec Sun Stone Design Metal Plate with Abalone Inlay

This item is a small, round decorative plate or coaster, approximately 4-5 inches in diameter, featuring a central design of what appears to be the Aztec Sun Stone (Piedra del Sol). The central motif is intricately embossed or debossed into a metallic material, likely brass, copper, or a base metal alloy, which exhibits a dulled, tarnished, or aged golden/bronze patina. The detailed relief work of the Sun Stone creates a textured surface in the center of the plate, showcasing various calendrical and mythological symbols. Surrounding this central medallion, forming the rim of the plate, is an inlaid border composed of multiple rectangular and irregularly shaped pieces of abalone shell, often mistakenly referred to as mother of pearl. These shell pieces display a vibrant, iridescent play of colors, including greens, blues, purples, and pinks, characteristic of abalone, giving the piece a distinct visual appeal. The shell segments are meticulously fitted together, forming a mosaic-like pattern. The overall construction suggests a combination of metalworking and inlay techniques. The metal rim encasing the abalone appears to be a uniform, perhaps rolled, edge. Signs of wear are visible, particularly in the form of surface scratches and nicks on the metallic surface, and a natural darkening of the metal due to oxidation, which contributes to its antique appearance. There are no clear manufacturer's marks or signatures visible from the provided image, making it difficult to ascertain specific origins or a precise manufacturing date; however, such items, often associated with Mexican craftsmanship, typically date from the mid-20th century onwards as tourist or decorative pieces. The craftsmanship, while not museum-grade, appears to be of good quality for a commercial or souvenir item, with the inlay work being relatively precise. The visible condition suggests it has been handled and used.
