Things You'll Need
Instructions
Visit the Emerald Creek Garnet Area in the Idaho Panhandle National Forest and purchase a garnet permit for the day. This permit costs between $5 and $10 and will allow you to pan for and leave with up to five pounds of garnet per permit. This is the only legal way to find star garnets in the wild in the United States. Note that the park is only open during the daytime between Memorial Day and Labor Day.
Take the materials that come with your permit, including your bucket of mining rough, the screen box and the shovel to the sluice. The sluice is the long, winding viaduct over which you'll do your panning.
Spoon one or two small shovelfuls of mining rough into your screen box. The mining rough is dirt and sand mixed with stones. You'll have to sift through it to find your garnets.
Submerge the lower half of the screen box in the water in the sluice. Make sure that the water doesn't reach the top of the box. Gently shake the box back and forth so that the sand and dirt sifts through into the water.
Remove the stones left in the box after all the sand and dirt is gone and examine them to see if you've discovered a star garnet. Remove any treasures you may have found and repeat this process with the entire contents of your mining rough.
