What Are Gems (Diamonds) in Pet Simulator 99?

In Pet Simulator 99, Diamonds and Gems are the exact same currency. The official in-game name is Diamonds, but the player community adopted "Gems" as a shorthand since it's quicker to type, and it stuck. Both terms are used interchangeably across trading sites, marketplaces, and the wider PS99 community.
In Pet Simulator 99, PS99 Gems touch almost every part of progression, and these are the main areas they cover:
Use Case in Pet Simulator 99 | What Diamonds Cover |
|---|---|
Upgrades | Enchants, potions, stat boosts |
Egg System | Extra hatches, Diamond Eggs |
Pet Management | Expanding equip slots |
Trading | Player-to-player trades |
Diamonds function as the standard unit of value in all player-to-player trades, and rare, powerful pets can command prices in the tens of billions. Some pets were only available for a limited time, so players selling them can ask for significantly more Gems, while more common pets go for considerably less. Community-maintained value lists track these prices regularly, giving players a reliable reference before entering any trade.
The maximum cap number of Pet Simulator 99 Diamonds a single player can hold is 1,000,000,000,000, which is 1 trillion as of Update 54. Players buying PS99 Gems in larger quantities should factor that cap into their purchase before placing an order.

Once the seller confirms and both sides accept the trade, the Pet Sim 99 Diamonds transfer to your account through the game's native trading feature.

How to Trade Gems in Pet Simulator 99?
Trading PS99 Gems is a built-in game feature, where players can trade pets, items, enchants, potions, hoverboards, booths, and Diamonds directly with each other through the in-game trading menu, accessible via the Inventory panel. You can send a trade request to any player who has trading enabled, and you can include any amount of Diamonds alongside other items in a single trade.
Here's how the trading process works in Pet Simulator 99:
Open your Inventory and tap the green and yellow trade button
Select a player from the active trading list
Add your Pet Sim 99 Diamonds or any other items to the offer
Review what the other player is offering
Both sides confirm and the trade completes instantly
Some items are marked as untradable and cannot be included in any trade, but PS99 Diamonds themselves are always eligible, making them the most flexible currency in the game. Before entering any trade, checking the current value of pets or items involved is a practical step, as community tracking platforms monitor market trends and pet availability, which can signal shifts in demand.
