The term 10X optical zoom means it has a real 10X zoom as opposed to a "Digital" zoom.

 

The optical zoom is a real zoom lens. The digital zoom is merely a cropping of the image and then the camera fills in a bunch of pixels to make up for the ones it cropped out.

 

The quality of digital zooms is awful.

 

A 10X optical zoom may or may not have a macro facility and the macro facility (If it has one) may or may not be able to focu close enough for jewellery.

Take the jewellery in to the camera store and test the cameras to find one that focusses close enough for what you want. (The joys of digital)
