This sterling silver pendant represents the Isle of Mann, one of the smaller Celtic nations. It features three legs and circa 1668 the Manx adopted the motto on their coinage "Quocunque Jeceris Stabit", translated to mean "Whichever way you throw, it will stand" (ref. isleofman.com). The three legged symbol does appear much earlier in Manx history.
This three legged symbol is very precious to those, and their ancestors, who hail from the Isle of Man.
The pendant is available in several chain lengths.
