To purchase diamonds, go to the shop and tap on the diamond offer you are interested in. You will then be taken through the purchase flow as controlled by your device.
To purchase anything in the game, simply tap on the item and you will be asked to confirm the purchase. Don't worry if you don't have enough - the game will ask if you want to top up the missing currency through an in-app purchase.
