I was wondering the first....but it’s a good thing the second aspect was raised for informational reasons.
I first saw irradiated diamonds back in the ‘80’s....but I didn’t find them attractive back then.
I think the rising popularity of Lab Grown diamonds will bring a greater acceptance.
And the technology has surely been refined.
I do agree that disclosure is essential
It brings mixed feelings for me. On one hand, I don't have anything at all against lab grown diamonds, though they aren't necessarily for me as I prefer natural. On the other hand, the idea of irradiating for color is something I don't like at all. It just makes it seem very fake to me. If the diamond growers would add nitrogen or boron for yellows and blues, I'd be more accepting of that than irradiation. It would still be artificial, but with the elements that produce the colors naturally, if that makes sense. I don't know how they'd get browns or pinks though.
Now all that being said, I could imagine buying a couple small lab grown blue diamonds to set along side my natural fancy intense green yellow, because I don't know if I'd ever find reasonably priced small natural blues. And I might even buy a wild neon green irradiated diamond. BUT I would always disclose that they were lab grown and irradiated whenever anyone should comment on it. It would, of course, be none of their business, but its just how I am. Full disclosure.
For the record, I also don't like cups under diamonds to make them look more yellow or pink or whatever. Gold color to enhance - good. Gold to make it seem something it isn't - not good. My feelings about 'deception' in any form might be a little extreme, lol.
