Cheapest camera for gemstone photography as well as domestic outdoor use?

I need to buy a latest digital camera for domestic use as well as for gemstone photography, but not expensive.
earlier i had casio exslim ZX 60, with that i could not take gemstone pictures.
i just noticed nikon S 3000 for $ 125. What about that? Any other suggestion?

Cheap small P&S cameras are just that… Cheap. Don't expect miracles beyond basic little snapshots.

Spend a little bit more on a decent bridge camera and you'll start getting somewhere.

However, many of even the smaller cameras are actually surprisingly good at simple macro shots, providing the photographer knows what they are doing. Usually problems like that are 100% user error.

You can't expect a small camera to do it all… YOU still have to make the effort to learn how to use it.
The more effort you make to educate yourself, the better the outcome will be. Even if you buy an expensive camera, it still needs YOU to use it properly.

Learn about your camera!

Read your manual! Read it several times, and practice in between. If you don't have a book, download a new one from the manufacturer's website.

Attend a class, read some books, read/watch online tutorials.

The major camera manufacturers (like Canon, Nikon, Olympus etc) all have very useful sections on their website for learning about photography.

Understanding at least the basic principles of photography (as well as being familiar with your camera) will enable you to make the most of your gear, and will make a HUGE difference to your images.
