Description by Derek Kaplan(from the App Store)
New phone. New York. Real players.
Diamond District: Trade Tycoon runs inside GemOS - a fully simulated operating system set in New York's diamond district. Launch apps. Check widgets. Customize your homescreen. Every app inside GemOS is its own world, with its own economy and real players behind it. The market runs 24/7. It doesn't wait for you.
■ MINE THE SOURCE - Own operations across three regions. Hire workers, manage contracts, pull diamonds, emeralds, and sapphires out of the ground. ■ HUNT RARE GEMS - Process raw stones into revealed gems. Color, clarity, cut, origin, treatment, carat weight. The rarest combinations carry odds beyond 1 in a trillion. Most will never surface in the lifetime of the universe. ■ DESIGN LUXURY JEWELRY - Freeform crafting with real synergy scoring. Your best work gets featured in Gloss Magazine. ■ TRADE ON WINSTON RESERVE - Stocks tied to real in-game activity. Short before earnings. Collect dividends funded by actual player fees. ■ TRADE ON DBAY - The player-powered marketplace. Buy and sell gems, jewelry, and papers with real users in real time. ■ CLIMB THE HALL OF TAPE - Every trade is public. The best ones get immortalized. Your name on the board means something. ■ RUN YOUR OWN LENDING OPERATION - Set your own terms through LoanShark. ■ BUILD REPUTATION - Every trade, contract, and article published adds to a score that controls your access. ■ WRITE THE NEWS - Earn a press pass. Publish on DD News. Shareholders vote on what runs. ■ MAKE IT YOURS - Customize your GemOS homescreen with widgets, icon packs, and layouts. Premium themes available via in-app purchase. ■ COMPOUND YOUR EDGE - Mining feeds crafting. Crafting feeds the marketplace. Fees fund dividends. The players who last build loops, not just trades.
