Antique Agate Pin
An antique agate pin brings together banded chalcedony and precious metal, offering a tactile piece of Victorian and Georgian adornment.
Antique Agate Pin
An antique agate pin takes several forms, predominantly appearing as brooches, kilt pins, and plaid fasteners originating from the Victorian and Georgian periods. These items frequently display Scottish Revival designs, utilising regional motifs such as dirks, broadswords, and shields.
The pieces on this page are heavily represented by Victorian Scottish silver work, incorporating polished hardstones like jasper, bloodstone, and moss agate. Buyers encounter circular pebble brooches alongside heart shapes and sword pins set with citrines.
The selection ranges from early nineteenth-century provincial silver items to late nineteenth-century specimens. Alongside Scottish pebble jewellery, French hardstone cameos set in yellow gold appear within the selection.
Materials and Construction
Silversmiths and jewellers shaped sterling silver, 9ct gold, 15ct gold, and 18ct gold into elaborate mounts designed to secure natural hardstones. Agate, carnelian, jasper, and bloodstone were cut, bevelled, and polished to display their natural banding and colour variations.
Metalwork techniques include braided silver bands, engraved basket-hilted sword designs, and claw settings that grip the stone tightly. Citrines and diamonds occasionally supplement the hardstones, adding contrasting yellow or clear facets to the silver and gold framework.

Distinctions in Quality
The calibre of an antique agate pin rests on the depth and variety of the stone's natural banding, together with the precision of the lapidary work. Stones with crisp, distinct colour layers command attention.
Workmanship in the metal setting separates standard production from superior examples. Finely chased silver, robust pin mechanisms, and well-balanced proportions in complex forms like dirks or broadswords indicate high-grade execution.
