Sterling 925 Lapis Necklace Unknown Mark

[BuyMania]

I got this beautiful necklace with an interesting marker's mark that I would like to find out more.
Necklace measures about 18 inches long with 7 dangle inset lapis stone with sterling bezel. Each bezel has a mark of "925" also.

There is a round tag with a mark like 2 trees and STERLING and (C).
My guess is this is from Norway, Denmark or Sweden.
I could be wrong and I appreciate any information to help identify this beauty! Please make sure you scroll to the right hand side to see the tag mark.
Thank you!
