Antique Agate Brooch
An antique agate brooch is a wearable piece of Victorian craftsmanship prized for its natural banded stones and distinctive Scottish revival designs.
What these brooches are
An antique agate brooch sits firmly within the Victorian era, spanning the mid to late nineteenth century. The examples met most often on this page belong to the Scottish Revival style, taking forms such as shields, knots, and circular pins.
Makers shaped these pieces as brooches and kilt pins, frequently incorporating additional gems like citrine, amethyst, and amber. The designs draw heavily upon Celtic motifs, resulting in distinctive wearable ornaments.
How they were made
The construction combines cut stones with precious metals, utilising silver, sterling silver, and gold. Lapidaries shaped natural varieties including moss agate, blue lace agate, Montrose agate, and banded agate into polished cabochons.
Metalworkers set these stones within detailed frames, employing techniques such as filigree and cannetille work. The mounts often take the form of shields or interwoven knots to secure the heavy agate stones.

Metalwork execution separates the average from the exceptional, with finer specimens exhibiting intricate wirework, clean soldering, and robust settings. The complexity of the Celtic shield or knot design further distinguishes the upper tier of these ornaments.
