Blue Valley
📍Highlands, North Carolina
Blue Valley is a vast expanse of National Forest in North Carolina’s Macon County. It offers opportunities to prospect for corundum outside of the pay-to-dig mines in the area. Plan for extensive hiking in dense forests with a chance of finding ruby and sapphire the hard way.

What can you find?
Blue corundum (sapphire) and almandine garnet are the headline finds, consistent with the broader Ellijay/Cowee-Buck Creek corundum belt that runs through this part of Macon County. As with most of this district, expect to be surface prospecting and creek-panning rather than tunneling — corundum here weathers out of the metamorphic host rock into stream gravels and hillside soil, so a shovel, screen, and patience go further than a rock hammer.
With a little bit of creek panning and sifting with a screen, blue corundum can still be found in the Blue Valley. It can be difficult to spot corundum in regular light among river gravels. Try using an ultraviolet light in the shade after concentrating some gravels or picking out some that you think may be sapphires. Ruby can also be found in the area, as it is simply just a different color of corundum. Almandine garnets are present in the area too and can be commonly mistaken for ruby without using a UV light. Typically, you’ll have best results using a 365nm UV light when looking for rubies/sapphires.
