You really need to look at websites like Park Cameras, Cameraworld, Warehouse Express, but ideally get to a store where you can physically handle the cameras. It is so subjective, and everyone has a different view.
There are some cameras I just can’t get on with, but may suit others.
As someone who has owned over time over 50 cameras of varying types, some will fit your needs more than others.
A DSLR is useful, as you can change the lenses and even buy a macro lens for close-up photography. I can recommend Nikon DSLR’s the D7000 , D300S, and for full-frame super quality the D700, D800, or D810, but they are quite expensive. Macro lenses are available 40mm, 60mm, 85mm, 105mm, and having the 60mm and 105mm I can select the best one for any subject. You can get very good depth of field with either and particularly the 60mm. Find a good second hand D300 or D300S Nikon body and a second hand macro lens, and you can get super results, or the Canon equivalent.
Look at Fuji cameras too. The more compact XE1 and XE2 have interchangeable lenses of very high quality and have a sharper image than even my Nikon DSLR’s. They do a super quality Macro lens, but even their standard zooms are bitingly sharp. Panasonic and Olympus, also do some excellent designs. Panasonic do a Lumix DMC range which is worth looking at.
I always recommend cameras where you have an exposure compensation dial on the camera, rather than having to go into menus.
A ringflash or circular flash is useful, and Metz are the best make, which I have seen discounted for around £220, but is so controllable as regards shadow reduction. I used it on an artist’s tiny mosaic ceramics and obtained wonderful results. There are good, cheaper ones out there, even second hand is worth looking at. Alternatively, you could buy two cheap small flashguns and position either side of the jewellery /silverware.
Finally, you might consider a polarizing filter to control reflections and the sturdiest tripod you can afford.
