If you’ve been grinding your way through 99 Nights in the Forest, you already know that diamonds are one of the most valuable currencies in the game. Whether you’re upgrading advanced gear, unlocking high-tier blueprints, or trading with elite merchants, diamonds open up a lot of opportunities. However, earning them efficiently can be tricky—especially in the mid to late stages when costs start to ramp up fast. Here are some tried-and-true strategies to help you earn diamonds quickly without wasting time or resources.

1. Prioritize High-Risk Exploration Zones

The deeper you go into the forest, the better the rewards. High-risk zones—especially those near the Infernal Ridge and the Ancient Ruins—offer a higher drop rate for diamond chests. Equip strong survival gear and stock up on healing items before heading out. These areas are challenging, but the risk pays off with rare loot and diamonds that drop from elite enemies and hidden caches.

2. Master the Infernal Chest Rotation

Infernal Chests are one of the best consistent sources of diamonds. They respawn every few in-game days, and each contains a random chance of dropping raw diamonds or diamond shards. Learn the respawn patterns and set a rotation path to loot them efficiently. If you’re playing in co-op mode, coordinate with teammates to divide the map and cover more ground between respawn cycles.

3. Participate in Update Parties and Seasonal Events

Events are often overlooked, but they’re a goldmine for diamond farming. Update Parties and limited-time challenges reward active players with premium resources. Completing event milestones, especially time-limited survival or building objectives, can earn you large diamond bundles. These events are also ideal for stockpiling gems, which you can later trade or use strategically to boost crafting speed.

4. Trade Smart with Merchants

Merchants in 99 Nights in the Forest have dynamic inventories that change every few in-game days. Keep an eye on their stock rotations, as some will buy crafted items or rare materials at higher rates. Selling refined resources like enchanted lumber or processed ores can yield a surprising number of diamonds. You can also use gems as barter currency in certain settlements, making it worthwhile to buy 99 Nights in the Forest gems early on to strengthen your trading potential.

5. Farm Diamond Nodes with the Right Tools

Once you unlock the Diamond Pickaxe or equivalent late-game tools, you can directly mine diamond veins scattered throughout the map. These nodes often spawn near cliffs or cave entrances. To make the most of your time, focus on mining runs after major respawn cycles. Combining this with the Miner’s Buff (if available in your build) drastically improves efficiency and drop rates.

6. Optimize Your Crafting Output

Some high-level crafted items can be dismantled for rare materials—including diamonds. If you’re sitting on surplus blueprints or excess crafted goods, use the dismantling mechanic to recycle materials. This approach is ideal for players who prefer to build and craft rather than farm. Investing in crafting efficiency upgrades early makes this method far more rewarding in the long run.

7. Consider Strategic Purchases

If you find yourself short on resources and want a faster progression route, you can buy 99 Nights in the Forest diamonds through official channels. This option is entirely optional but can help you skip certain grind-heavy phases—especially if you’re aiming to unlock late-game content quickly. The key is to use purchased diamonds wisely for upgrades that provide long-term benefits rather than temporary boosts.

Final Thoughts

Earning diamonds in 99 Nights in the Forest is all about balance—between exploration, event participation, crafting, and smart trading. Each of these strategies can work on its own, but combining them creates a steady income stream that keeps your progression smooth and rewarding. Whether you prefer to grind for hours or play more casually, these methods ensure you’re never short on one of the game’s most essential resources.
