Q&A: Choosing a Radiant Cut Diamond Within a C$2.5k-$3k Budget

By Mike Fried,

Hey,

I’m picking out a radiant diamond (0.8 carat range, 2,500-3,000 CAD$). I’ve found several ones I like, but have very thick girdles like this one:

Or they have what I observe to be a bowtie effect and darkening in the middle:

How would the larger girdle effect the look of the diamond… I can’t really tell.

I wouldn’t recommend this diamond as it has strong fluorescence and might end up looking hazy/milky. For DEFG diamonds you should get only none or faint fluorescence. The girdle is not an issue, as long as it’s not extremely thick/think, it’s fine.

And you are right, this one has a prominent bow-tie.

I found this one that looks much better:

The one you suggested looks great. It says it’s girdle is ‘very thick’ though, what are you thoughts about that? I’ve also taken a look at similar diamonds in the 0.70 carat range in case I want to spend a little more on the setting – do you have a suggestion in that range?

What would you think of this one I just came across: www.jamesallen.com/loose-diamonds/radiant-cut/0.69-carat-d-color-vs2-clarity-sku-5525543?a_aid=dmnd1357

Very thick girdle is still fine. And it didn’t look bad in the video.

This one is cut a bit too deep and the inclusion on the table is also a concern. It might be noticeable in person.

How about something like this?

I had a couple more diamonds I would love you opinion on for piece of mind. I do like both the 0.8 and 0.7 carat’s you suggested above.

For a 0.7 carat I saw the following
www.jamesallen.com/loose-diamonds/radiant-cut/0.70-carat-g-color-vs1-clarity-sku-7730987?a_aid=dmnd1357
How would that compare to the one you suggested? I know the cut is deeper and the polish is not as good – are those noticeable for the price difference?

For a 0.8 carat I found the following:
www.jamesallen.com/loose-diamonds/radiant-cut/0.82-carat-h-color-si1-clarity-sku-7611270?a_aid=dmnd1357
I spot a tiny inclusion on one of the corners, do you think that is worth the price difference ($300) from the one you suggested? How much does the depth% affect the brilliance?

www.jamesallen.com/loose-diamonds/radiant-cut/0.70-carat-g-color-vs1-clarity-sku-7730987?a_aid=dmnd1357
This one is cut a bit deeper, but it’s not the worst. It’s an ok diamond and it’s even slightly larger than my recommendation.

www.jamesallen.com/loose-diamonds/radiant-cut/0.82-carat-h-color-si1-clarity-sku-7611270?a_aid=dmnd1357
This one is even deeper than that, but it’s not terrible. It’s absolutely eye-clean. It’s the largest of them all so if size is your priority, go with this one, it’s still going to make a nice ring.

Thanks for all your help. I ended up choosing the original 0.8 carat you suggested.

Cheers!

That’s fantastic news! I’m glad you liked my suggestion so much!
