The Luckenbooth design dates back to the luckenbooths (locked booths or shops) of Edinburgh situated on the Royal Mile in the 15th century, and initially housing mainly silversmiths and goldsmiths.

The crown when present on a Luckenbooth signifies Mary Queen of Scots; but it doesn't need a crown to be a Luckenbooth (the term represents a wide range of heart designs sold from 'locked booths').

The Luckenbooth Brooch is a traditional Scottish love token given by men as a betrothal or wedding brooch. It could also be pinned to a baby's shawl to ward off the devil.
