While researching this maker I came across a matching bracelet and a matching pin but no necklaces anywhere to be found! (The matching pin is listed on Ruby Lane with another shop).
I've seen this link described as a leaf design with catkin. It certainly is a stylized leaf design with a textured center. To me it is also reminiscent of the Hawaiin anthurium flower.
The necklace is in excellent condition. It has a toggle clasp and measures 15". Each of the 14 links measures 1 1/16". It weighs 36.5 gm.
It was designed and made by Aarre & Krogh (1949-1990) of Randers, Denmark. This piece, as most Danish silver pieces are, is beautifully crafted. It will undoubtedly garner many compliments.
