Any help on knowing the exact use for this chain? and maybe the date?

The two ends of the chain go inside both berries , the purple berries are made of enamel and although the piece is unmarked its tested for sterling silver.

Hi, please look to this kind of jewelry, it Russia we call it "loriat".

Hi,
Yes, it`s called lariat necklace in English, without clasp, either tied into a loose knot if long enough or fastened with a ring or a brooch.
Regards

Thanks for the information from both of you :).
