Pewter Westward Expansion Diorama on Iron Pyrite Matrix

This decorative art piece features a cluster of cast pewter figurines mounted atop a large, natural mineral base. The base is a significant specimen of iron pyrite, commonly known as 'fool's gold,' exhibiting a dense, sparkling crystalline structure with a brassy-gold metallic luster. Atop this rugged mineral terrain are three finely detailed pewter elements: two riders on horseback and a single stylized evergreen tree. The figures appear to represent a scene from the American Old West or Westward Expansion, with the riders shown in an active, galloping pose. The craftsmanship of the pewter components shows a high level of detail in the texture of the horses' coats and the riders' attire. The contrast between the cool, matte grey of the pewter and the warm, geometric glint of the pyrite matrix creates a striking visual aesthetic. Based on the style and typical production of such mineral-mounted giftware, this piece likely dates from the late 20th century (circa 1970s-1990s). The condition appears well-preserved, with the pyrite showing typical natural fissures and the pewter exhibiting a mild, even patina. No visible maker's marks are discernible from this angle, though such items were frequently produced by specialty studios like Hudson Pewter or similar boutique mineral gift companies.
