I believe that when the mark is transliterated, it is read Yiyuan. I have no information on this mark. It might be a regional or retailer's mark.
This is not a mark designating silver content. The bracelet might still be silver or contain some silver, but if so I would suspect it to be of a lower grade. It is hard to say from photos, but there appear to be some spots of minor brassing.
The overall impression, from the photos, is one of relatively recent manufacture, probably in Nepal or Tibet. Of course someone else, in particular someone who could examine the piece in person, might have a different opinion.
