It's crazy to prefer a natural diamond for anything other than a collectors' item. It's not about being 'cheap' - whatever your budget is, if you're picking an engagement ring say, why not get a technically superior (or larger) stone for the same price tag?
I pitched this to my wife a few years back. She insisted she’d rather have a smaller natural diamond. It makes no sense to me. Shiny carbon is shiny carbon to me. There’s no real logic in it. But given it’s a status symbol that derives its value from its rareness, I suppose it’s no different than a Luis Vutton or a Rolex. It’s not about the function, it’s about the fact that you can afford one. I hate that mentality,…
Hah!
The big issue with choosing a smaller, natural stone is you can't really be sure it's actually natural. The industry has so many unethical practices I wouldn't be confident in any "certification" that comes with a stone's origin. Even lower-grade stones might just be from lab rejects, or labs intentionally growing good, but not perfect stones.
