Brasslight UAE. I think they closed their Dubai shop (used to be in The Curve building on SZR), but still have a showroom in Abu Dhabi and I believe in Jebel Ali, need to check their website.
Alternatively, Heritage Touch in Al Quoz (it's in the street where the Sun & Sand Sports Outlet store is, just a bit further down on the right hand side) or the Antique Museum (Al Quoz, opposite Al Serkal Avenue in a side street)
