Zircon Peak

Welcome to Zircon Peak, your own gem cutting workshop.

Every order starts as a rough stone full of hidden inclusions. Spin it, study it, then lock the facet angle on the protractor. Round, Emerald, Pear and Cushion cuts each demand their own ideal refractive angle; land close and the fire inside the stone comes alive, miss wide and the light leaks away.

Three grinding stages stand between you and a finished jewel: coarse, fine and polish. Tap only while the steadiness marker rests inside the green zone. A shaky hand scratches the stone and costs you clarity.

Finished gems are graded by fire, clarity and carat weight, then sold for coins. Spend your earnings in the shop on six real upgrades: steadier gloves, a magnifier lens, a faster coarse wheel, premium polish compound, master angle templates and a lucky charm.
