Antique Agates
Antique agates encompass hardstone carvings, jewellery, and small silver boxes spanning the Georgian, Victorian, and Edwardian periods.
Antique Agates
Antique agates include personal adornments and functional desk or dressing items created across the eighteenth, nineteenth, and early twentieth centuries. Brooches, rings, vinaigrettes, and watch keys form the core of the selection.
Scottish Revival pieces dominate the jewellery offerings, featuring banded, Montrose, or moss agates mounted in silver or gold. These items reflect regional nineteenth-century lapidary traditions.
Smaller boxes, pill boxes, and cutlery handles integrate natural chalcedony with precious metals, demonstrating the versatility of hardstone in domestic objects.
How they were made
Lapidary artisans shaped chalcedony, carnelian, and jasper using cutting and polishing techniques to reveal natural banding and colour variations. Stones were then set into sterling silver, 9ct gold, 18ct gold, or gilt brass.
Silverwork and goldwork techniques such as champlevé enamel, hand engraving, and filigree support the hardstone elements in brooches, fob pendants, and napkin rings. Fitted hardwoods and horn provide structure for larger decorative objects.

What varies in quality

The craftsmanship of the metal mounts, whether intricate silver pebble work or detailed gold chasing, dictates the refinement of the piece. Maker attribution and well-preserved structural integrity elevate specific items.
