This is a 10mm uncoated Gibeon bracelet, originally sold as individual beads by a natural stone shop a long time ago. It was a bit short, so I added one 12mm coated Gibeon bead and an 11mm Libyan glass bead, but it was too heavy, so I rarely wore it. The inner diameter is about 15cm, so it might be a bit small for men. I can adjust the size if you'd like, using crystal beads, etc. ^^ I didn't like the shiny coating, and since fakes were circulating, I was particular about it being natural at the time. ^^ Some beads have cracks, but please understand that this is an iron meteorite. m(_ _)m The rough stone in the picture is not included. ^^;
