How to get diamonds in Hayday

You'll get more Diamonds every time you level up, and it might be worth synching the game up with Facebook for a few extra free Diamonds. At level 24 in Hay Day you can begin mining - another source of this precious currency.

Another way to get more Diamonds in Hay Day is to keep an eye out for the purple tickets that sometimes appear near your newspaper. Once you've watched a clip, you'll be able to claim a handful of free Diamonds.

Another smart technique way to get more diamonds is to collect all seventy eight achievements (3 levels) Every time one of these levels is completed you're given a ribbon and a couple of diamonds. Through the same menu, you'll can also challenge Game Center friends by beating their scores or earn more achievements. Those challenges are sort of races where the first to complete that goal gets the reward. Note: you must claim the accomplishment reward in order to get it.

Finally you can be mining for Diamonds:
Zoom into the mine
Leave the game
Turn on “Airplane Mode”
Go back to your Hay Day farm
Mine with the shovel 2-5 times
If you don’t get any diamonds, stay in the game until the disconnect appears. Then leave game and hard close it. Turn airplane mode off - And you still have all your shovels, so you can try for diamonds again.
Once you get the diamond and you want to KEEP IT, you HAVE to go BACK to settings and QUICKLY turn off airplane mode before the disconnect appears. Also, you have to work in small quick batches. Mine 3-5 times and stop to wait for disconnect.. OR go to settings to turn off airplane and save the games progress.

Open your mine and use TNT. It will produce diamonds every couple of blasts. When you have enough diamonds, pay for Tom's service and have him find nothing but TNT and load up on it. Then blow the mine and use as much metal as you can, again more diamonds will come every couple of blasts. Sell what metal you can't store. But you have to use tom and get a bunch of TNT.
