Here's a delightful modernist Sterling silver wrap-around ring by the leading Norwegian silversmith, David-Andersen (see bio). It features a composite dark green and black stone cabochon. It has been called 'Uni's Lucky Charm' ring, so I presume it was designed by Uni David-Andersen.
Condition: Excellent, no visible damage
Marks: D-A, 925S, scales, Norway-Sterling
Size: Current finger size is UK L, US 6, EU 51/52, but as this is wrap-around, it is adjustable to several sizes up or down.
