Offered is an excellent and early true Victorian Scottish agate pebble brooch or specimen brooch, most likely circa 1850-80, or perhaps a bit earlier, judging by the long pin and the simple brass casing and the overall design. This piece features a good range of colors that really show up in natural sunlight, and the central stone has an interesting inclusion of crystals that is like a miniature geode.
This brooch measures just over two inches (five cm) across, and is in good antique condition, with minor hairlines (see picture of central stone) and normal signs of use, but there are no major cracks or hairlines and no chips or losses. The surface has a clean polished appearance and looks great in the light. All in all an excellent example of this form, both subdued and entrancing; it will wear or display beautifully!
