A diamond conducts heat, so a jeweler uses a probe that confirms that the stone you're evaluating indeed meets this criteria.
If you're interested in the quality of the metal, there are other tests that will give you this information.
all you have to do is the ring
A fake ring will have lots of color to it. You should also be able to see flaws inside a real diamond such as small air pockets. Real diamonds also have code numbers on them which only a diamond..
Show your diamond to a professional jeweler. They can usually tell you right away whether the diamond in an engagement ring is real or not. Another way to tell is to breathe hot air onto the diamond to fog it up. If the diamond holds the fog for a few seconds, it's fake. Real diamonds disperse the fog immediately. Professional testing is by thermal and electrical conductivity measurements, or by optical study of the crystals.
Real diamonds will cut glass, though there is speculation that some fake diamonds can cut glass, and that you can damage a real diamond by cutting glass with it. Another way to tell is to hold the diamond up in the light. If you see any orange color from the diamond, it is fake, as real diamonds have every color EXCEPT orange.
You can tell if a ring is real gold or not by putting it near a magnet. If the ring is attracted to the magnet it is not real gold, real gold is not magnetic at all.

The only real way to tell if a diamond is real is to let someone look at it that knows what they are looking at. They can tell you if it is a genuine diamond and tell you what quality it is. There are tons of imitations. There are diamond testers that pretty well for about $100.00 also. If the ring is inexpensive and the diamond looks clear not yellow with no visible imperfections, clouds, or black dots; then that sounds too good to be true. I'll attach a little more info about diamond quality as a resource.
I have a white gold and diamond ring stamped JWBR and it is definatly real.

The prices between a real diamond ring or a moissanite engagement ring can vary greatly. Generally, real diamond rings are up to 1000% more expensive than moissanite rings.
Take your jewelery to a local jeweler who can look at it, inspect it and tell you what it is made of and the gems it contains.
No
A better test is with a probe, which your jeweler will use to tell you if the diamond is a real diamond.
Yes it's real
No. This is not Harry Potter, magic is not real.
Drop the stone in a glass of water and see if it sinks to the bottom. Due to its high density, a real diamond will sink. A fake one will float at the top of the surface or in the middle of the glass.
