Antique Victorian Scottish Granite Brooch Pin

Sturdy antique brooch. No markings, but my research shows this to be most likely from Scotland in the Victorian era. Not marked, but it's sterling with what appears to be granite and marble details. -9.5 grams -1.5 inches across In very good vintage condition with considerable tarnish and a high-quality pin.
