Orfèvrerie Wiskemann genuine pearl necklace with sterling clasp

A classic 17" necklace of about 70 individually knotted white pearls which flash a little silvery in some lights. Created by the Brussels silversmiths Orfèvrerie Wiskemann, whose history dates back some 150 years. Marked 925 and the company mark of OW with a globe on the clasp, which remains a bit tarnished. The necklace is in otherwise excellent shape.
