Q&A: Choosing a 2.30 Ct. Emerald Cut Diamond for a Yellow Gold Vintage Setting With Up to $18,000 Budget

I’m really sorry, but I won’t comment on Brilliant Earth’s products. We find their company distasteful and can’t recommend them to people. https://www.diamonds.pro/reviews/brilliant-earth/

As for the three diamonds from JA, I’d go with the second one:

The black windowing effect is the least pronounced there and the overall specs are great.

However, I’d go even lower in color for the setting you chose:

www.jamesallen.com/loose-diamonds/emerald-cut/2.01-carat-i-color-vs1-clarity-sku-4893321?a_aid=dmnd1357

These two diamonds would look identical when it comes to color and you’ll save a lot.

The setting is beautiful. Generally speaking, the fewer side diamonds, the more the center stone stands out. You picked a perfect one for this. And if you like the style, it’s all good.

I wouldn’t go with that one because of the medium fluorescence on a G color. It usually causes a hazy/milky look even though it’s not visible on the screen. https://www.diamonds.pro/education/fluorescence

The I color ones are still my favorites

I don’t recommend either one.
1) IGI isn’t a good lab. https://www.diamonds.pro/education/igi/
2) Strong fluorescence should be avoided on I+ diamonds. https://www.diamonds.pro/education/fluorescence/

What do you think of this one?

The second one is gorgeous:

But it’s no longer available. Have you put it on hold?

Fantastic! Good choice.
