"Snuff Container" or "Urn"

I obtained this over ten yearsago. I was told it was bought overseas many years before that.  It is metal and the inside looks to be silver but there are no markings. There are 10 gems embedded on each side. Long looks to be brass chain 13 inch in length.  There looks to be a 1/4 inch brass band around the entire item to bring both sides together. Weight is 7 oz..

Looks to be handmade and very ornate.Reminds me of those containers that in asia would be used for incense and swing around,  but there is no opening except for the top which does close tightly. Could be some sort of brass on the outside but the inside is definately silver color with soldering or weld points along the inside seams. The top is hinged. Someone told me this could be a "snuff container". Looking forward to selling this but do not know what to call it or describe it properly in the ad. Hoping it worth lots of money but I have not won the lottery yet and this also is probably a long shot :-)

Please feel free to ask any questions that might help you identify this item.

By the way, there is no smell on the inside from liquor or drugs. Not that I know what drugs would smell like on the inside :-)
