This sterling silver band ring features celtc knot design going to the way around it. Rhodium plating to prevent tarnishing. The width of the ring is approximately 4mm. The mixture that is created with Swiss technology also makes our sterling silver extremely hard like 14k gold rings. Unlike regular sterling silver rings that tend to bend out of round, our rings retain the perfectly round shape under normal daily activities. It is virtually a carefree wedding ring. High quality finish gives it the elegance of any fine jewelry.
