What digital camera can I use to have a good quality of picture for some of my crystal jewellry?

The reflection allways changes the image. The picture is far bad from the real jewellry.

Hi, I suggest you get a camera that states it has a macro (close up) facility. If you look at reviews on line, pay particular attention to that part of the review discussing how good the macro facility is. Major digital camera review sites (e.g. Imaging resource, or www.dpreview.com) usually rate a camera's macro facility, often with an image of a coin or a banknote. They vary quite a lot. p.s. - if you buy a camera that takes filters, you could try a polarising filter on the lens - they cut down on reflections.

Use any digital camera brand which supports upto 3 Megapixel of resolution.
Incase you want to buy a digital camera then NIKON L1 would be a good buy.

Jewelry is very hard to photograph. The trick to making it come alive is not the camera however, but the lighting.
* Use any camera that has a macro lens
* Use a tripod
* Place the jewelry against a neutral backgroud.
* Get some spotlights in there to illuminate the jewelry. Try different angles and different distances from the subject. Try direct light and reflected light. Rotate the jewelry. Play with things untill it looks great through the viewfinder.
* Shoot the picture - obviously without any flash.
