seal ring / Williamite Memorial, 1701

Williamite Memorial Seal-Ring. Silver inset with cornelian with an incuse device of a griffin on a turret. The brass mount of the stone is engraved with Masonic symbols and the inside of the ring itself with the legend 'Jefferies Obt Dec 1701 agd 97' and more crudely scratched 'Ubique' and (?) Iiemdis. 'No Surrender' scratched similarly on the outside. Possibly used as an Orange Lodge seal late in its working life.;
