Here is an extremely rare pair of Sterling silver earrings by the renowned Orkney silversmith Ola Gorie (see bio). I have never seen this design before and am guessing it is a very early model. The earrings are fitted with posts for pierced ears, but these could be substituted with screws if you wish.
Condition: excellent, no visible damage
Marks: OMG ST SIL, as well as 925 on butterfly backs
Size: 2.5 cm ( 1") long
