An elegant Scottish agate brooch crafted in 18 karat yellow gold, centering a beautifully polished banded agate of elongated navette form. The agate displays striking natural coloration, with deep smoky brown and black tones framed by a soft pale grey band, creating a dramatic, eye-shaped silhouette that is quintessentially Scottish in character. The stone is bezel-set and surrounded by a finely worked gold border featuring blue enamel dot decoration, accented with delicate rope-twist wirework along the inner edge. The refined enamel detailing adds a subtle yet vibrant contrast to the warm gold and moody agate. The navette shape, rope-twist wirework, and blue enamel dot motif are all hallmarks of Victorian Scottish jewelry, often associated with mourning or Highland dress. The reverse reveals a traditional closed-back construction with a sturdy horizontal pin and C-catch, consistent with 19th-century Scottish jewelry craftsmanship. The brooch is substantial yet elegant, designed to sit gracefully on a lapel, bodice, or tartan sash. A timeless and collectible example of Scottish jewelry, rich in symbolism and craftsmanship, equally suited to a serious collector or a striking modern wearer. Please note: The green jewelry box...
