A finely crafted Scottish Arts and Crafts brooch by Robert Allison of Glasgow, featuring a polished cabochon of soft pink rose quartz set within a decorative sterling silver mount. The circular design is typical of Allison’s early–mid 20th century work, combining Celtic revival motifs with hand-tooled detail. The silver frame is adorned with raised bead accents and intricate foliate patterns, bordered by a twisted rope edge that reflects the artisan’s distinctive craftsmanship. The natural rose quartz, with its gentle translucence and subtle internal inclusions, catches the light beautifully. A classic example of Allison’s fusion of traditional Scottish design and refined silversmithing.
