Celtic brooches are used for fastening women’s scarves or plaids. A plaid, (rhymes with "maid"), is a tartan sash or cloak worn by either sex.

The Luckenbooth brooch is a traditional piece of Celtic jewelry that takes it’s name from the "locked booths" where they were sold in Edinburgh in the 16th and 17th century. Similar to the Claddagh, the design incorporates a heart and crown. The origin of the design came from the royal monogram of Mary Queen of Scots. A luckenbooth brooch is frequently used as a love token because of the heart motif.

The Celtic perannular brooch is designed with a pin crossing a circular opening, working similar to that of a belt buckle. The penannular brooch has a break in the ring so that the pin may pass through and be twisted to lock it.

The Celtic annular brooch also is designed with a pin crossing a circular opening, but is more secure thant the perannular brooch in that it works by pulling cloth through the center, which is then pinned through.

The most famous Celtic brooch is the Tara Brooch, now in the Irish National Museum. The Tara Brooch looks like a penannular brooch in shape but since the ring is solid, it cannot attach in the same way.
