This ring has a centered wide inlay of meteorite centered between two 1mm inlays of sterling silver.  There are lands of titanium separating the metals to add a unique contrast to the surface.  The meteorite used is the Gibeon Meteorite, and is estimated to be over 4 billion years old!  It has a unique crystalline grain structure called Widmanstatten lines that were caused by the meteorite slowly cooling over millions of years as it hurtled through space.  The ring shown is 7mm wide with a flat profile and the titanium is the brushed finish.
