You may not sell diamonds because once you collect a certain amount in a game, they are converted into money or green cash. You earn 5 bucks for every diamond that you collect. The only items that can possibly be sold as of now are booster cards that are worthless and cannot be fused. For instance, let's say you have a level 5 (5 stars) Treasure Crates card. If you receive another Treasure Crates card by leveling up, purchasing a booster pack, or redeeming artifacts, then an option to sell cards will pop up in your cards menu underneath the Buy Cards button. When opened, you will see your useless Treasure Crates card there and you will be able to sell it. In conclusion, you can only sell the boosters cards that are useless to you for very little money.
