Hi elfkin! Welcome!
You'll want to purchase a digital camera which has a Macro mode. Macro modes allow you take very close-up shots of subjects such as flowers, jewelry, insects, etc.
In addition, it's a good idea to use a tripod for macro shots. This helps prevent camera shake.
I'm not a professional photograher but have taken some fairly satisfactory photos of jewelry without using a lot of expensive equipment and special lights. You can see some of them here:
http://bykari.com/gallery/index.htmI took these particular photos outside, under an awning. The day was bright but overcast. The light was diffused so there were no harsh shadows. I used white paper for the background, though a white cloth would work too.
I put my digital camera in macro mode and set it on a tripod to get close to the subject. My camera was also set in single auto focus. Every time you press the shutter release button with your finger, there is a chance of camera shake, particularly at slow shutter speeds. So I use the camera's self-timer when taking close-up shots.
Many digital cameras have Macro modes and most work extremely well. I've heard the "older" Nikon CoolPix 4500 is an excellent consumer digital camera for close-ups. It has a split body design and excellent quality lens.
Cameras with swivels LCDs should also be considered. You can change the position of the LCD to get a better view of the image when the camera is positioned at an awkward angle.
