Instructions
Sort your rock collection by color, size and texture. This will make identifying specific rocks easier. Purchasing a collector's box or some other means of sorting and storing your different rocks will make the process easier.
Contact a gemologist, a specialist who can identify rock types by sight. Ruby and rock mines can be found throughout western North Carolina. Ask the gemologist or shop owner at the mine to look at your rock collection. The worst case scenario is that you will have to buy a bag of dirt and sift it in the mine trough. After sorting your dirt, take the accumulated rocks, plus your own rocks, to the mine staff for identification.
Take your rock collection to a geologist. Geologists can be found at universities and museums.
Search online for a North Carolina-based rock or gem site that has identifying pictures of various rocks.
Check with a local hobby shop, gem shop or ruby mine. Many have posters or identification charts that will assist in rock identification. These charts can also be purchased online.
