Sell Ores Gears Guide
Every Growth Gem, Coating and Cleanser with live costs and when to buy.
The Gear Shop sits in the market at the centre of the Sell Ores map. Every Gear is single-use: a Growth Gem starts a timed regeneration burst the moment you confirm, and a Coating stamps one mutation onto one ore until you cleanse it. Prices climb from $500,000 for a Small Growth Gem to $25T for a Devil’s Growth Gem, so the shop is a mid-to-late-game sink, not a Floor 1 toy.
This page is the live cost table for the August 2026 patch. Pair it with the Mutations ranking when you decide which Coating to stamp, and with the Money Making loop when you need to fund the next purchase. Codes such as PETFUSION and EXPANSION on the Active Codes list still hand out free gems, so check there before you buy the same item for Cash.
How to buy Gears
- Walk to the market in the centre of the map. The Gear Shop shares the plaza with the other purchase stations.
- Open the Gear Shop and pick the item you can actually afford. There is no purchase cap — you can stock several of the same Gear if your wallet allows it.
- Confirm the buy. A Growth Gem starts its timer immediately. A Coating asks you to target one placed ore. Once used, the Gear is gone and you must buy another copy to repeat the effect.
Do not buy a Growth Gem while half your slots are empty. The multiplier only helps ores that are already regenerating. Fill the base, park your Drones, then pop the gem.

Growth Gems and Coatings do different jobs. Gems are a timed burst across the whole base. Coatings are a permanent multiplier on a single ore until you spend an Ore Cleanser. The Devil’s Growth Gem is the strongest burst in the shop — 12x for 15 minutes — which is why PETFUSION is still the most valuable code in the Codes Hub.
Growth Gems versus Coatings
Use a Growth Gem when:
- Every slot is filled with the best ore your Floor can roll.
- Drones are upgraded and you plan to sit in the server for the full duration.
- You are about to claim a long Diary Rewards window or a Time Skip so the burst is not wasted on idle slots.
Use a Coating when:
- You have a high-tier ore you intend to keep for days, not minutes.
- The mutation multiplier beats the next Drill or Speed upgrade for that specific ore.
- You can afford the matching Cleanser later if a better Coating drops.
Never Coating a Common Copper on Floor 1. The x1.5 Rusty tag on a cheap ore is a rounding error; the same Cash into Drill Level pays for itself on every ore you own. Save Coatings for Mythic and Ascended pieces listed on the Best Ores page.
When each Gear is worth the Cash
Small Growth Gem ($500k). The first shop gem most players can afford. Five minutes at 2x is a rounding error on Floor 2 and a real spike on Floor 4+ if every slot is Epic or better. Prefer the free Small Growth Gem from EXPANSION before you buy this.
Ore Cleanser ($1M). Cheap insurance. Buy one the same day you stamp your first Coating so you are not stuck with Rusty on a Voidshard you later want to Galaxy.
Rust / Frost / Crystal. Stepping-stone Coatings. Rust is only worth it if you already rolled a keeper ore and have spare tens of millions. Crystal at $1B is the first Coating that feels like a real upgrade on Floor 5 Mythics.
Void / Alien / Galaxy. Endgame stamps. Galaxy at x5 and $1T is the ceiling. Do not Galaxy an ore you plan to feed into the Fuser in the next cycle unless you understand the mutation carries (or does not) through that fuse — check the live tooltip before you confirm.
Large / Super / Devil’s Growth Gems. These are session tools, not collection items. Super ($15B, 6x/15m) and Devil’s ($25T, 12x/15m) only pay off when the base is already at Floor 6–7 with Drones online. Burning Devil’s on a half-empty Floor 3 is the most expensive mistake in the shop.
Funding the shop
Gear prices outrun early Cash by design. The path that actually reaches Crystal and beyond is the same loop as the rest of the wiki: Drill and Speed first, Floor unlocks second, Mythic rolls third, Fuser cycles fourth. The Profit Calculator and the Drill & Speed chart tell you when a shop purchase is cheaper than the next stat level. If the calculator says the next Drill level returns more Cash per hour than a 5-minute gem, buy the Drill.
Codes still matter here. EXPANSION is a free Small Growth Gem. PETFUSION is a free Devil’s Growth Gem that would otherwise cost $25T. Redeem both from the Active Codes list before you open the shop with Robux or a panicked Cash dump.
Common Gear mistakes
- Buying a gem with empty slots.
- Coating a Common or Rare ore you will sell in ten minutes.
- Skipping the Ore Cleanser and locking a bad mutation on a Mythic.
- Spending PETFUSION on a B-tier Pet instead of saving the Devil’s gem for a Floor 7 fuse — see Pet Fusion.
- Ignoring the Group Rewards Time Skip, which can cover the same idle gap a Small Growth Gem is trying to patch.
What to read next
Once you know the shop prices, rank the mutations on the Mutations page, then put the Cash plan back on Money Making. Floor order still lives on Floors & Unlocks.
Frequently Asked Questions
Quick answers to the most common questions.
Where is the Sell Ores Gear Shop?
In the market at the centre of the map, next to the other purchase stations. Walk there from your base; it is not inside the gear/settings menu you use for codes.
Are Gears permanent?
No. Every Gear is consumed on use. Growth Gems start a timer immediately. Coatings last on that ore until you spend an Ore Cleanser or replace the ore.
Should I buy Small Growth Gem or wait for EXPANSION?
Redeem EXPANSION first from the [Active Codes](/codes/all-active/) list. Only buy the $500,000 shop copy if you need a second burst the same day and every slot is already filled.
What is the strongest Gear?
Devil's Growth Gem is the strongest timed burst (12x for 15 minutes). Galaxy Coating is the strongest permanent mutation (x5) if you can afford $1T.
Does Ore Cleanser work on Prismatic or Ascended ores?
Cleanser removes Coating mutations. Ascended and Prismatic flags from the Fuser and the August 25 patch are separate systems — read the in-game tooltip before you spend $1M.
