Be careful... If it sounds too good to be true, it probably is. Find a jewelry store locally, not one of the big chains either. Get educated and know what you're buying, that way you don't throw big money away on inferior jewelry. I got a crash course from an old jeweler and he explained and showed the difference between real quality metals and stones and the cheap, bargain priced ones. You might want to invest a little more up front (and maybe have to wait a little longer) before going for the instant gratification and settling for something that's lower quality.
Or go for the less expensive stuff and have fun with it. Ultimately as long as you're happy, it's a good decision, as long as you're not being taken for a ride by an online discount jeweler and overpaying.

Don't buy via a web. Go to a thrusted jewelry shop. Their is too much fraud around that on the internet and shipping is too dangerous.
