Rock hard with these beautiful stone eyelets made by Diablo Organics! Diablo Organics knows how to turn precious materials into brilliant jewelry. These double flared eyelets are made of Hematite and polished to a high sheen, to make the stone really, really stand out. Hematite is fairly heavy and will show off a grey, mirror finish when thoroughly polished. Double flared, so you won't be needing any o-rings to keep the jewelry in place.
