How many diamond face cards are in a deck of cards?

A normal "pack of playing cards" is called a deck. In a deck there are 4 suits. In a suit there are 13 cards. The name of each individual card in order from lowest to highest value (values may vary depending on the game) is as follows: 2♥♦♣♠ 3♥♦♣♠ 4♥♦♣♠ 5♥♦♣♠ 6♥♦♣♠ 7♥♦♣♠ 8♥♦♣♠ 9♥♦♣♠ 10♥♦♣♠ Jack♥♦♣♠ Queen♥♦♣♠ King♥♦♣♠ Ace♥♦♣♠. The name of each individual suit (all values are equal almost all the time) is as follows: ♥Hearts(red) ♦Diamonds(red) ♣Clubs(black) ♠Spades(black).

Just to clarify my answer, their are 13 red diamond cards in a pack of 52 playing cards.
