14k or 18k domed shape black stone timascus, gold lined 6mm 8mm
Seen here at 6mm wide also available in 6-8mm (please indicate in the notes while checking out) Available in either 14 or 18k, white yellow gold. This technique is what I call "stone finish" made of Zirconium and titanium. This one has a large portion as zirconium vs titanium.
