Likely-handmade vintage belt buckle with a Cowboy bull riding scene set against an abalone shell inlay border in a Southwestern composition. The central gold-tone bull rider figure is captured mid-buck on the bull, with abalone shell pieces forming a textured perimeter that catches the light in iridescent flashes of blue, green, and purple. The maker is unidentified and a search for similar buckles has not turned up a match - very likely a one-off or small-batch handmade piece from a Southwestern silversmith. Has natural patina and scuffs consistent with usage of a vintage item. All abalone pieces remain in their settings, no missing inlay, no damage to the central relief. The combination of bull riding subject matter and abalone Southwestern craft makes this a crossover piece for rodeo and Native American style collectors. Standard bar-and-swivel attachment fits any standard 1.5 inch belt.
