Country of manufacture
FINELY BOUND IRREGULAR LODESTONE, engraved “N” and “S” at the two poles. Measuring 2-1/4″ x 2-3/4″ x 2″ (6 x 7 x 5 cm) overall, the brass is beautifully shaped to accommodate the natural form of the stone. It features large iron plates to concentrate the force, and a swiveling brass suspension ring. Constructed with a type of naturally magnetic magnetite stone, it dates 17th / 18th century, in very fine condition, retaining noticeable magnetism. Such mounting and assembly was often done in Western Europe, the stone itself coming from Eastern Europe or Russia. The lodestone was of course essential for the early navigator, to apply and then restore as necessary the magnetism of his compass needle, without which he would be literally lost.
