The Eccentric Meteorite ring has an offset hole so that a larger stone can be held than would normally be possible with a symmetrical ring. On symmetrical rings, as stones get larger, the ring has to get thicker in order to accommodate the stone. The offset allows the fingers to stay closer together while still having the larger stone. The inlay is genuine Gibeon Meteorite that is over 4 billion years old and fell from outer space and landed in Namibia, Africa sometime in prehistory. It has a unique crystalline structure due to it cooling over millions of years in space. Metals native to Earth don't have this unique structure. Truly out of this world.
