This ufo looks really strange. It has a kind of a box, but you can't open it.
You cannot wear it on a necklace, so no idea where they use this for.
Also the country / maker is a mystery. It is marked.
Originally perhaps a single locket, with a stuck hinge. Try some Imal to make the hinge work again.
The oriental looking decorative triangle with spatulas (2 missing) was added later, marriage.

:::: I had something like this once & do a search for "Chinese Opium Chatelaine" and it has something to do with the preparation of Opium. :::::
:::: The box part even looks like an opium poppy head, at least to my eyes, the search results seem to suggest that this is a Chinese Opium Chatelaine:
:::: Initially I was thinking India because the tiny silver discs are similar to the tiny silver Chuckram coins of the Travancore Kingdom. :::::
::::: The hallmark might be in the script of the Travancore Kingdom, but there are so many separate languages and different cultures in India. ::::::
