The best way to get this crop is through Rare Seeds, which you can get from the traveling trader, who will sell them for 1000g in summer or 600-1000g in any other season. Another option is to reproduce a rare seed from a sweet gem berry using a seedmaker, to reproduce a seed from a harvested crop. When you manage to get a rare seed, it will take 24 days to cultivate Sweet Gem Berry.
As they are not considered a fruit, you will not be able to use them in a barrel or canning jar.
Harvesting a Sweet Gem Berry nets you 64 XP, and you can sell it for, 3000g.
It is also possible to exchange a Sweet Gem Berry for a Stardrop at the Old Master Cannoli statue in the Secret Woods.
Now that you know how to get Sweet Gem Berries on Stardew Valley, we hope you are more than ready to get these berries.
