The nine of diamonds playing card is often referred to as the "Curse of Scotland" There are a couple of reasons given for this connection:

1. It was the playing card used by Sir John Dalrymple, the Earl of Stair, to cryptically authorise the Glencoe Massacre. Certainly there is a resemblance between the nine of diamonds and his coat of arms.

2. The Duke of Cumberland is supposed to have scribbled the order for "no quarter" to be given after the Battle of Culloden on a nine of diamonds playing card.
