Vintage Finnish Kalevala Koru large white metal brooch high quality Engraved decor Pewter? Scandinavian designer jewelry Viking style Sun symbol Finland

high quality An old, large and pretty mysterious brooch.
Intricate shape and decor. As far as I know, it is very rare.
The Finnish Kalevala Koru Oy is deservedly famous for their replicas of historical Viking jewelry, and this brooch feels really authentic. The shape indicates it is a solar symbol, but the colour refers to the Moon.
Marked KK on the backside.
Circa 6 cm x 6 cm.
Nice vintage condition.
