In cartomancy with playing cards, the Two of Diamonds (2♦) is the letter card.
All twos in cartomancy relate to the idea of movement, but the Diamond suit is restless, ethereal and intellectual, so the movement in this case is a movement or information and ideas.

In its most simple interpretation, the Two of Diamonds therefore refers to letters, telephone calls, messages, etc. This meaning applies easily to all fields of life, so that there is no need to further explain it. More broadly, the card refers to everything that is written, including letters, books, receipts, tickets, etc.

Due to its connection to information, the Two of Diamonds is also a card of research, of searching and of wading through the facts to find the key to the issue. In this sense, its psychological significance comes to the fore, as it describes someone who is curious, inquisitive, suspicious even, depending on the other cards. If a person has a lover and the official partner comes up with the Two of Diamonds next to them, they may be perking up their ears.

In a more positive sense, this card covers all that concerns the elaboration of plans. It represents intelligent effort to achieve something.
