In cartomancy with playing cards, the sevens in general represent the idea of achievement.

The Seven of Hearts has the general meaning of surprise. This is because the suit of Hearts does not contemplate the notion of effort, so anything that happens happens either thanks to other people or thanks to positive circumstances. This card signals positive turns of events, fortunate breakthroughs and good luck. It is also connected with the idea of talent, because if we have a talent for something, achieving great results in it is easy.

The Seven of Clubs is less fortunate. It is a card of problems, things that stand in the way of achievement and that need to be worked through. It is not a tragic card. Sometimes it limits the amount of success shown by the other cards, while at other times it signifies that the sailing will be less than smooth. Either way, the problems shown by this card are solvable (which doesn’t automatically mean they will be solved). Supported by positive cards, the Seven of Clubs becomes a card of hard-won achievement. It can signal the conclusion of an agreement or that of a practical project.

The Seven of Diamonds is the card of money and financial achievement, and of achievement in general. It is a simple card most of the times. Unlike the Seven of Hearts, here effort is implied. By extension, this card is positive for recognition and winning prizes, and allegorically it is connected to harvesting.

The Seven of Spades is a card of misfortune. It shows obstacles that are difficult to solve, against which the querent has little power. More broadly, the card has to do with all negative unforeseen circumstances that either prevent us from achieving what we want or strongly limit us. With positive cards it shows that success won’t be complete, while with negative cards it’s a sign of utter capitulation.
