- Fine Grit (400-600): This stage polishes the rock, revealing its natural colors and patterns.
- Extra Fine Grit (1200-1500): This final stage produces a high-gloss finish.

The tumbling duration for Lake Michigan rocks can vary depending on the size and type of rock. Generally, it can take anywhere from one to two months to achieve a smooth finish. Here’s a rough estimate of the tumbling duration for each stage:
| Stage | Duration |
