lab created diamonds are a strange breed. Thanks a LARGE part to the bastards at debeers.
There is a stigma against them, and all the labs that make them have to go to a TON of effort and trouble to mark them so they are "easily distinguishable" from a real diamond.
That being said, depending on how shady you are, there are HUGE deals to be had.
And some of the newer processes, (not really legal to be imported into the US, gotta love regulations by debeers) DO introduce seemingly "random" imperfections into the diamond and slightly different crystal structures.
They aren't really random, cause you would have 2 diamonds the same size, exactly identical. But without having the 2 to compare, it's MUCH harder to tell lab versus real with the new gen.
Now all that said, it depends your size and price point. If you're looking in the 1/2-1 carat stone size, it's barely worth the hassle. If you're going for the oh my dear god that's a tennis ball on her finger style, then lab could be the way to go.
I have a friend down here who's dad is a "bit on the shady side" and he always kept promising his wife a bigger diamond one of these anniversaries. For their 30th he got her a 4 carat stone. (I think, it was around there give or take .25) Slightly sketch, imported, then he got it certified via brazil. So technically, it's a legit stone.
He paid I want to say around 25k for the stone and certification.
It was considered D/E color (right on the border) VS1/2 (once again, that's not much difference)
For a "proper" stone he'd have been looking around 80-90k.
So for him, HUGE savings.
But I know for me, I had a friend who was a jewler make the ring, and I'm slightly less sketchy. (OK a lot less) Difference of price would have been negligible. BUT I was doing a 1 carat stone.
That being said, I have a feeling eventually my wife will want an upgrade too.(probably upgrading me, but that's another thread
) But I'm putting it off as long as I can.
But no matter what you do, unless it's giving her a huge family heirloom stone, GET HER INVOLVED. Let her make the decision, otherwise you'll be paying hell for it for the rest of your marriage.
If she's cool with cheap, great, if not, great. BUT it's her diamond. You wouldn't be happy with her telling you which brand lift to run, or "but you can get these little retread tires so much cheaper" so same thing. If it's important to her, let it be important.
