Red Gems can be obtained from Graves, as a drop from Red Hounds, from trading a Sextant to Wolly, from Earthquakes and Stalagmites in Caves, and from Ancient Statues, Broken Clockworks, and Ornate Chests in Ruins. They can also be found as a single, one time drop from hammering the Sunken Boat.
In the Shipwrecked DLC, Fishing with Trawl Net in deep Ocean has a small chance to catch a red gem. The chance is higher during Hurricane Season and Dry Season. Magma Piles in Magma Field biomes also have a chance to drop them.
In Don't Starve Together, the Dragonfly drops 2 Red Gems upon death. Red Gem Deer also drops one of them if killed or if Klaus is killed. Red Gems can be used to craft a Scaled Furnace or inserted into Cratered Moonrocks to acquire a Red Moonlens. They can also be used to power Winona's G.E.M.erator.
