I'm afraid I have to disagree with Trev on this one. Living in Australia, I've seen a lot of Yogya silver due to our close proximity to Indonesia and It having been (and possibly still is) the no1 holiday destination for Aussies. With holidays, come souvenirs and so now there are at least 1/2 dozen pieces are for sale online any day of the week here and the decoration of your box does not feel right to me.
Yogya silver designs are stylised representations of local things such as lotus flowers, peacocks and Wayang puppets. The flowers aren't quite right and I believe the centre urn contains fruit which look like pears to me.
When I first saw the box, my immediate reaction was Italian...more food for thought.
