2.7.1

August 22, 2026

■ Loose gemstones are now more realistic across every system. ■ New Loupe view lets you inspect gems anywhere they’re available for purchase. ■ Inclusions make every gem one of a kind. Previously implied, they’re now visible across different clarities. ■ LoanShark revamped - request loans, review payment history, settle old defaults and use new collection methods. ■ Two new home screen themes, plus Settings app improvements. ■ GEMEX UX rebuilt - more intuitive, with a focused, one-thing-at-a-time flow. ■ Quick Reveal - the ceremony is now optional. ■ Gem Calc improvements. ■ District - now opens onto the street. Tap any storefront to step inside and buy gems, jewelry, and cards directly from the keeper. ■ District fixes, plus shop/street performance and UX improvements throughout. ■ Handbook rebuilt, with a new Obsidian memo and a cleaner first-phone experience with improved onboarding.

10/10

I absolutely love this game but when is there more content coming for the offline Solo empire? Multiplayer is fun but sometimes it can get overwhelming

Get it now.

Awesome fun game to pass time. If your into diamonds and gems this is the one for sure.

In awe

If this game got taken off the App Store. I’d give my first born son to have it back. 24 male no banana for scale

The best economy simulation

This game is an excellent sandbox for the analytical and ambitious. Take the opportunity to try this out if you’ve ever enjoyed a eco building game in the past. Developer in the game, small niche community growing. Patch’s and updates every two weeks. No ads or pay to win by design. Best game in the AppStore. If you’re wired this way.

Best game out there tbh

Nothing to critique about this game, it is very complete. Just needs more a player base to thrive. Devs are constantly updating the game, just needs to market the game better i guess.
