Diamond proportions

[braydbraywilli]

Is this diamond worth buying? It scored a 0.8 on the HCA but I have read here that there is a less chance of obstructions while viewing the diamond close if the pavilion is above 40.6 degrees.

We need the magnified 360 video to evaluate further. Can you put it on hold and share the report number?

I know technically a 33.5 crown angle isn't recommended, but that stone sure looks pretty on the video!

(But I'm *not* an expert, so take this with a tablespoon of salt. I was just excited by the video )

I thought so too. I have been down a research rabbit hole the past couple days after learning the importance of crown angle, table depth, and pavalion angle. I know the calculations aren’t 100% due to rounding and I thought this would be on the safer side due to the hearts and arrow grade. Thanks for the input!

I think the cut is fine based on the video, but the CVD material is questionable. Not sure if it’s the video setup or the graining/straining making the face up a bit blurry. I think there are safer options for the price.

Yes, I thought the video was simply out of focus? Like the focal depth was off. But maybe it’s the material?

I think this is more favorable in proportions. I am planning on purchasing this stone and believe the video looks better.

I like this a lot better than the previous stone.

if you're still open to suggestions, here's one with slightly better cut precision.

@kim N’s 3.74 has less pavilion twist and more edge to edge brightness. But your second choice is definitely a good cut, too.

Thank you for the recommendation. I thought 58% tables weren’t ideal though? Is that not true?

 

[0515vision]

Tables of 55-58 are within recommended PS proportions. And remember that the whole conglomeration of angles needs to work together. That’s why we don’t just go by the numbers of a certificate. @kim N’s pick is a really great stone.

+1 to 0515vision. 55-58% is definitely considered ideal, and we use all the proportions along with the magnified video and light return images (when available) to evaluate a stone.
