If you need diamonds to get forward in the game, this article below will be helpful for you. It can be slow work to simply harvest diamonds in the field, so try these tips to get diamonds fast.
Once you achieve the Basic rank, you can begin to enter codes. Select the pet icon at the bottom of the screen. Then, open the Exclusive Shop and scroll to the bottom to find the Codes bar. This is where you will enter the codes to boost your gameplay.
Currently, there are no codes to give you diamonds in the game, but this could change since there have been diamond codes in the past. In the meanwhile, you can still redeem codes for boosts that will help you earn more while harvesting in different worlds.
Upgrades can be used to improve you and your pets' performances. Some upgrades are for strength and speed, but the important one here is that you can increase diamond spawning.

The Upgrades machine can be found in the second world on the right-hand side. Walk up the ramp and into the lit circle. Once you do, you'll be prompted with the screen above. Make sure you have diamonds handy to buy your upgrade.
