Huh? Everything is worth diamonds. Like 20 Grass is 1 Diamond, 64 Iron is worth 1 Diamond, or if your looking at rares other than spawners, Emeralds are worth slightly more than 1 diamond There are also too many rares to list. Trading Prices [NET] 2.0 | Skyblock Forums ^ for more item values by KingDG But if your looking to farm stuff and sell, Dc of logs are 2-5 diamonds Dc of Stone/cobble is 0.5- 1 diamond Hope this helped.
Basically above. Everything can be worth diamonds. Usually the less rare the item is the more of it is needed to cost 1 diamond (eg Stone/logs/cobble). The trade thread is just a rough guide on someones opinion on what the prices are. The prices in that thread will vary depending on your needs.
