Diamond Safe & All Safes: Gems, Lockpicks, Time Capsule

Updated 2026-09-02 · Roblox Storage Hunters: Open World

The Diamond Safe always awards Diamonds when opened. Whether it gives "15-20 gems every time" is not documented yet: the Fandom pages confirm the payout is guaranteed and that it scales up with the safe's mutation and grade, but no fixed range is recorded. Figures like 15-20 gems per safe are community-reported, unconfirmed.

"Gems" and "Diamonds" are the same currency. The game's Beginner's Guide calls them Gems, every other page calls them Diamonds 💎. Do not confuse the currency with the Gem and Diamond mutations, which are item modifiers (10x and 8x value multipliers).

Five safe types exist. Metal, Code and Diamond Safes plus the Diamond Vault drop in all areas; the Junk Safe is Junk Yard only. Each safe opens instantly if you own the matching lockpick from the Shopping Mall Locksmith, or takes time if you hand it to the Locksmith.

All safes: where, contents, value

Safe	Rarity	Where	Contents	Value	Instant-open lockpick
Metal Safe	Epic	All Locations	Loot items (luck and tier of loot not documented)	Varies	Basic Lockpick, $250
Code Safe	Epic	All Locations	Loot items (not documented)	Varies	Steel Lockpick, $1,000 (10% slower spin)
Diamond Safe	Epic	All Locations	Always Diamonds; amount scales with mutation and grade	Varies	Precision Lockpick, $15,000 (20% slower spin)
Diamond Vault	Legendary	All Locations	Always Diamonds; exact amount not documented	Varies	Master Lockpick, $150,000 (30% slower spin)
Junk Safe	Epic	Junk Yard	Not documented	Varies	Not documented

"Varies" is the exact value the item database records for every safe; the wiki does not list a base sell price for any safe type. Mutations on any safe raise the value of the safe itself. Only on the Diamond Safe do mutations and grades also raise the loot: since Version 0.4.1 (July 6, 2026), rarer mutations and higher grades give a larger Diamond payout. Cleaning, weather and exclusive mutations do not change the Diamond payout.

A Business Bay hotfix confirmed Diamond Safes, Vaults and certificates can drop there too; specific item names are not documented yet.

Diamond Safe payout: what is documented

Always awards Diamonds when opened.
Mutation and grade increase the number of Diamonds (grade a Diamond Safe before opening it if you want more).
Putting a Diamond Safe in the Time Capsule unlocks a mutation, which raises the payout but does not change the safe's Luck or tier.
The Safecracker accessory modifier (head slot) makes Diamond Safes and Vaults pay out more Diamonds while worn; the exact bonus is not documented.
The base amount and any range per grade are not documented yet.

The Diamond Vault (Legendary) follows the same rules: guaranteed Diamonds, and cleaning, weather and exclusive mutations do not affect the payout.

Gems vs diamonds

Term	What it is	Used for
Diamonds 💎 (also called Gems)	Progression currency, separate from cash	Upgrades (inventory, selling space, advertising, tip jar, plot capacity), Staff upgrades, plot expansion, Luck Drinks, Gavel Loadouts, extra Locksmith/Grading/Cleaning slots, Time Capsule fees
Gem (mutation)	Item modifier with flashing four-point stars	Multiplies item value by 10
Diamond (mutation)	Item modifier shown in blue	Multiplies item value by 8

How to get more gems

Documented Diamond sources:

Customer tips when an item sells. Regular NPC and Celebrity Customer tips are soft-capped at 65 💎 per hour. Upgrade the Tip Jar and Celebrity Customers perks to raise the tip chance.
Items with the Mint mutation always give a Diamond tip on sale, and that tip does not count toward the 65/hour cap.
Opening Diamond Safes and Diamond Vaults.
Finishing quests and collections.
Buying with Robux.

Luck Drinks at the Energy Cafe cost 12 💎 (+50% Luck), 25 💎 (+150% Luck) and 65 💎 (+300% Luck).

Locksmith

The Locksmith is on the right side of the Shopping Mall. It opens safes and sells lockpicks for Money. Owning the matching lockpick tier opens that safe or vault instantly from your inventory; bringing it to the Locksmith to be picked manually always costs time instead, even if you own the lockpick.

Lockpick	Price	Opens up to	Net worth to unlock
Basic Lockpick	$250	Metal Safe	$500
Steel Lockpick	$1,000	Code Safe	$3,500
Precision Lockpick	$15,000	Diamond Safe	$95,000
Master Lockpick	$150,000	Diamond Vault	$450,000

Locksmith slots: slot 1 is free, slot 2 costs 50 💎 at $10,000 net worth, slot 3 costs 150 💎 at $50,000 net worth. At $50,000 net worth you also unlock the third Grading and Cleaning slots and the Barn Garage.

Safes can also be lockpicked directly from the auction screen. Failing 3 times jams the safe, and a jammed safe can only be opened at the Locksmith.

Three consecutive Junk Yard NPC quests ask you to open 5, 10 and 10 Junk Safes, so keep them rather than quick-selling. Separately, Daily Club Quest "unlock safes" objectives only count safes lockpicked from the auction screen, not ones opened at the Locksmith (jammed safes included).

Time Capsule

The Time Capsule sits behind the Shopping Mall and unlocks at $100,000 net worth. It applies one of four special mutations to an item. Placing an item costs 5 💎 to 250 💎 depending on the item's rarity and existing mutations.

Once inside, the item rolls every 5 minutes until one of the four mutations lands. The total chance per roll is 3.125%; only one Time Capsule mutation is applied.

Mutation	Multiplier	Chance per roll	Final chance
Cobwebbed	1.2	2.5%	80%
Antique	2	0.5%	16%
Ancient	5	0.1%	3.2%
Timeless	12	0.025%	0.8%

Rules:

A Time Capsule mutation only raises sale value. It does not raise trophy accessory stats or the luck/tier of safe loot, except on Diamond Safes, where it raises the Diamond payout.
Displayed Gavel Trophies with a matching mutation (Cobwebbed, Antique, Ancient or Timeless) improve the chance of rolling that same mutation.
An item that already has a Time Capsule mutation cannot go back in. A Mutator Extractor Potion (3.4% roll at the Alien Market for 25 Alien Coins) removes it so the item can be re-rolled.
Whether the capsule keeps rolling while you are offline is not documented yet.

Gavel Trophy and other trophies

Gavel Trophies are won at auctions in every area (Legendary, base value $50). Displayed on your plot, they raise the chance that auction items appear with mutations. See base and house for plot layout.

Feature	Documented value
Display limit	3 trophies, or 4 with the Extra Gavel Trophy gamepass (449 Robux)
Trophy Capacity upgrade	1→2 costs 45 💎, 2→3 costs 95 💎 (140 💎 total)
Mutation slots per trophy	3
Maximum boost per trophy	+250%
Stacking	Trophies carrying the same mutation stack together

How to place a Gavel Trophy in your base

Place the trophy on your plot like any other displayed item; the Trophy Capacity upgrade sets how many can be out at once. To save a display, open the Luck menu (the "+" button next to the Luck stat), arrange gavels on the plot and press Save. Loadout 1 is free, Loadout 2 costs 200 💎, Loadout 3 costs 300 💎. Loadout gavels are stored outside your inventory. Trophies placed in a Clubhouse boost only their owner, and loadouts do not extend there.

To compare trophies, multiply each modifier by its mutation multiplier and add them: a trophy with +67% Silver and +123% Gold scores (67 x 2) + (123 x 4) = 626.

Other trophies are ordinary sale items with no documented display effect:

Trophy	Value	Rarity	Where
Glass Trophy	$1,025	Rare	Business Bay
Race Trophy	$1,040	Rare	Cargo Ship
Bloxy Trophy	$50,000	Legendary	Business Bay
#1, #2, #3 Trophy	N/A (base value not confirmed)	Mythical	Club Tournament
