You also should see a video of them. Best a 360video to look at the inclusions. I’m a bit wary of buying diamonds for over 10k like that. I would want much more information.
And to bring in my personal opinio if you really want size - why not go with some high color, high clarity lab diamonds from James Allen?
If the mined part about the diamond is important to you I still would get certified mined diamonds.
Being in Australia it would be a big risk to buy something like that if and bringing it here (shipping and import taxes) and if you are not happy with it, then sending it back etc would be a nightmare.
I personally wouldn't buy an I clarity diamond, especially if it is not graded by one of the top labs. Instead I'd opt for a slightly smaller one that has a better cut and clarity and is graded.
Have you seen these in person? Who graded them? GIA or jeweler? Clarity of I1/2 is usually pretty included (visible). They could appear ”frosty” or “speckled” depending on how legit the grading is.
We need more information, pics, specs even.
Do you only want big?
Do you want big, sparkly, clear and lively?
Big but frozen spit? (Lol sorry)
We need more information. Not all diamonds are the same.
Also, what are the measurements of them?
Can I make a suggestion (apologies in advance), have you considered lab created diamonds? You might get a better deal than buying overseas and getting such a low clarity/cut?
Open to suggestions so don’t mind at all. I prefer earth mined, I have selected a few stones from JA. Not going ahead with these stones. Thank you.
For bad or for good when I see diamonds that included I think "worthless." I am so glad you did not purchase these. Honestly- what good is a pair of diamond earrings if they are not beautiful?
