The fastest way to get diamonds in Storage Hunters Open World is to stack every reliable source in one routine: claim daily rewards, take NPC quests, open Diamond Safes at the Locksmith, progress the Collection Book, and finish nearby Achievements instead of farming only one activity.
Diamonds are one of the most useful progression currencies in Storage Hunters Open World, so the best farm is not a single spot or one lucky locker. Your goal is to make every normal session push several diamond sources at once: login rewards, safes, quests, collections, and achievement progress.
That means your auction and looting runs should never be separate from your diamond grind. If you are already buying units, selling items, and raising your net worth, you should also be checking which rewards those actions are moving forward.
Best diamond farming routine
STEP 1/5
Claim the daily reward
Collect the free login reward at the start of every session so your diamond balance builds even on short plays.
STEP 2/5
Open any Diamond Safes
If you obtain a Diamond Safe, take it to the Locksmith instead of leaving it sitting in your inventory.
STEP 3/5
Check NPC quests
Talk to quest NPCs around the map and keep objectives active while you loot, bid, and sell.
STEP 4/5
Fill the Collection Book
Keep collecting items from areas such as Back Alley, Cargo Ship, and Farmyard so milestone rewards keep moving.
STEP 5/5
Finish nearby Achievements
Open your Achievements and target anything close to completion, such as auction wins, playtime goals, or other progress challenges.

Diamond sources worth prioritizing
| Method | Best use |
|---|---|
| Daily Rewards | Free diamonds over time; claim every login. |
| Diamond Safes | Burst diamond rewards after unlocking them at the Locksmith. |
| NPC Quests | Extra rewards while completing map objectives. |
| Collection Book | Long-term milestone diamonds from discovering items. |
| Achievements | Progress bonuses from auctions, playtime, and other goals. |
Daily Rewards are the easiest diamond source because they only require logging in and claiming the reward. They are not the fastest source in one session, but they are free, consistent, and worth collecting before you do anything else.
Diamond Safes are better for burst rewards. You first need to obtain a Diamond Safe through gameplay, then bring it to the Locksmith to unlock it. Each safe gives a random amount of diamonds, so treat safes as high-value bursts rather than a fixed payout route.
The Collection Book is a slower but strong long-term source. As you discover items from different areas, your completion rises, and certain milestones let you claim diamond rewards. Achievements work similarly: they reward bigger progress goals, so checking what you are close to finishing can turn normal play into extra diamonds.
Pick up NPC quests before you start bidding so every auction run can also move quest, collection, achievement, and net worth progress.
Make auctions feed your diamond farm
Do not treat diamonds as a separate grind from the rest of Storage Hunters Open World. The same auction run that gives you items to sell can also raise your net worth, add new Collection Book entries, move quest objectives, and push Achievement progress.
When you have a choice, bid with purpose instead of buying random units. Better-looking units and stronger areas can improve the value of your haul, which matters because more money and higher net worth can help you access better progression opportunities.
KEY!After each run, sell and flip items cleanly, then check what changed. If a Collection Book milestone is ready, claim it. If an Achievement is one or two actions away, finish it before drifting into another random auction. This is how normal looting turns into a steady diamond routine.
Diamond Safe and Locksmith requirements
Diamond Safes need two things: you have to obtain the safe through gameplay, and you have to take it to the Locksmith to unlock it. They are one of the more exciting diamond sources because the payout is random, which gives them better burst potential than waiting only on daily rewards.
Some Diamond Safes can be blocked by your net worth. If the game does not let you open one yet, keep selling valuable items, winning useful auctions, and building your account value first. Once your net worth is high enough, return to the Locksmith and try the safe again.
Avoid planning around exact safe payouts or exact net worth cutoffs. The reliable habit is simple: open safes as soon as you are able, and use normal auction profit to reach the requirements for any safes you cannot open yet.
Mistakes that slow diamond farming
| Mistake | Fix |
|---|---|
| Relying only on Daily Rewards | Use them as free income, then farm safes, quests, collections, and Achievements. |
| Ignoring NPC quests | Pick up quests before looting so normal play earns extra rewards. |
| Skipping Collection Book claims | Check milestones after discovering new items from different areas. |
| Forgetting Achievements | Target goals that are already close to completion. |
| Opening safes late | Take Diamond Safes to the Locksmith as soon as you can use them. |
| Bidding randomly | Choose units that help value, quests, collections, or safe access. |
| Expecting one farm to stay best forever | Stack every diamond source as your net worth and map access improve. |
Most slow diamond farming comes from playing too narrowly. If you only wait for daily rewards, you miss the faster burst from safes. If you only spam auctions without quests or collection checks, you leave milestone diamonds unclaimed.
The better approach is to keep a short loop in your head: claim, quest, bid, sell, unlock, check, repeat. That keeps every session pointed at diamonds even when you are mainly farming cash or items.
Later boosts to keep in mind
As you progress, events, trophies, and higher-value areas can make your overall looting stronger. Treat those as bonuses that improve the same routine, not as a replacement for the daily reward, Diamond Safe, NPC quest, Collection Book, and Achievement loop.
If an event or later area gives you better loot opportunities, fold it into your normal run: take quests first, bid with a purpose, sell for net worth, open any safes, and claim progress rewards afterward. The method stays the same even when the quality of your loot improves.
Frequently Asked Questions
What is the fastest way to get diamonds in Storage Hunters Open World?
The fastest routine is to combine Daily Rewards, Diamond Safes, NPC quests, Collection Book milestones, and Achievements in the same session. Farming only one of these will usually be slower.
Are Diamond Safes worth opening?
Yes. Diamond Safes are worth opening because they give a random diamond payout and can deliver faster burst rewards than passive sources. Take them to the Locksmith whenever you obtain one.
Why can’t I open a Diamond Safe yet?
Some Diamond Safes require a higher net worth before they can be opened. If the Locksmith will not unlock one, raise your net worth through auctions, selling, and flipping items, then try again.
Do Daily Rewards give enough diamonds by themselves?
No. Daily Rewards are useful because they are free and consistent, but they are slow by themselves. Use them as the first part of your routine, not your whole diamond farm.
Should new players focus on quests or auctions first?
New players should do both together. Pick up NPC quests first, then run auctions and looting while those objectives are active. That way, your early money grind also works toward diamond rewards.
