An antique Scottish Agate Bar Brooch (often called a "baton" or "tartan" brooch), most likely dating back to the Victorian or Edwardian era (around the late 1800s to early 1900s).

The Stones: Those three cylindrical tubes are made of highly polished natural gemstones. The outer two are red carnelian/agate and the centre one is white chalcedony (milky quartz). This specific red-white-red layout was made to mimic the stripes found in traditional Scottish tartan cloths.

The Metalwork: The stones are held together at the ends by decorative, engraved metal caps (brass) shaped like tiny leaves or claws, with matching metal bands across the middle to stabilize the cylinders.

The History: Scottish "pebble jewellery" became incredibly famous across the UK in the mid-to-late 19th century because Queen Victoria fell in love with Scotland and bought the Balmoral estate. People would wear these bar brooches to secure heavy wool plaid scarves, cloaks, or lapels.

It measures approx. 46mm x 12mm
