How to Play: Click to select, buy, and confirm. Hold and drag across a stone to scrape it open.

Tap a jewelry slot to place a gem template, then drag to move it, pinch/scroll to resize, and rotate to fit.

Click the collect button to save a finished stone, double-click jewelry to add it to your collection, and click any collected item to remove it.

Buy rough stones and scratch them open slowly—every rock hides rich color, hairline cracks, or nothing at all.

Take the dealer's cash offer mid-scratch, or hold out to craft rare gems into jewelry for bigger profits, and grow your gem workshop!
