I care more about where the jewelry was made than where I buy it from. It's probably all mostly the same crap china stuff though anyhow. I wonder if any specifies being made in the states.
I dunno where the diamonds in my wife engagement ring came from, but it was made by a shop in Texas that sells on Amazon. They called me several times over the course of it being made for her to make sure they got it right.
I've bought a few rings from Amazon and been quite happy. So much so, I don't imagine ever buying from a local jeweler again, since they comparatively so expensive.
My wife bought me a $300 tungsten ring for my birthday one year. I subsequently lost it a few months later. I bought what seemed to be the same ring on Amazon for $50 to replace it. A few weeks later, I found my original ring. To this day, I can't tell which one is which.
So, is the one from Amazon is a lower quality. Is there a way to justify the higher price from the local jeweler? I have no idea, nor do I care.
Jewelry typically has a 50% or more markup to start with....like most retail goods.
Your best bet though is to go with a company that stands behind their sales with a good return policy. If you buy something from Amazon, make sure it's sold BY Amazon and you should be safe.
I'd be ruluctant to buy diamonds online as many may be cloudy or inferior. They're difficult to buy in most big box jewelry stores without paying significantly more than what you should. They will often rate stones as "At least a I-J color" instead of giving you a GIA certified stone.... They show you a lot of inferior stuff so when they pull out the real bling, you are inclined to pay their markups to get what you should have been shown to begin with.

If you goto the right sites you can get magnified images of the stones along with all the measurement you can put into a brilliance simulator and photos of the certs. However if you're buying anything online of real value I'd insist on GIA. EGL, etc tend to be very loose. I bought a stone this way and ended up with something that is near perfect under a loupe. I knew about any inclusions ahead of time. Color clarity was spot on, and the cut was great. Nice thing is you have a much wider selection online than you'll find local. When I looked locally nearly everything was garbage for cut. Might colorless F, but uniformity, etc were always crap.
The best thing about jewelry is no matter where you go, it's always 75%+ off everywhere, every time.
