I did a quick calculation for 0.314 , E VS2 = $847 (Wire Price)+ $ 55 (Shipping) = $902 in total , Ideal weight 0.313 ct , Crown angle = 15.3%

WhiteFlash for 0.327, E, VVS2 = $909 (Wire Price including shipping) , Ideal weight= 0.324 ct , Crown angle= 15%

With just a price difference of $7 , would you think the first rock would be a better choice in terms of its spark knowing that the crown angle is more than 15% (i read your blog ) And in your opinion, which properties of the rock that takes precedence , the clarity or the ideal cutting weight or the crown angle approach?
Clarity may or may not affect the performance of the diamond, depends on the location of the inclusion. For the WhiteFlash VVS2, I am pretty sure no inclusion will stand in its way. The video of the diamond is giving me so much confidence that that diamond can perform. Even the contrast level in the certificate itself looks good.
As a matter of fact, if we want to talk about fire performance, this diamonds should be able to perform very well:
https://www.whiteflash.com/loose-diamonds/r...id=myengringexp (affiliate link). This is the 0.313ct F VVS1 you listed out yesterday. The hearts and arrows looks great, maybe some minor bending tip at the heart at 5 o'clock position but looking at the hearts and arrows on the cert, it hearts look great, so I would say this diamond has perfect hearts and arrows. The only reason I did not choose this is because the video of the diamond did not attract my attention as much as the 0.327ct E VVS2 or the 0.307ct D VS1.
Now, if I were to buy a diamond again, I would really go for E VVS2, considering the value for money it brings over Brian Gavin Diamonds. The contrast level is there to bring this diamond alive. However, if I were to buy based on specs, I would go with F VVS1 - That diamond should be an excellent performer and I don't think the video can show how well it can perform. Did you see how steep the angle is and how high the crown height is? . the calculated weight is exactly the actual weight as well! I am actually looking forward to buy more diamonds from WhiteFlash to check things out if possible, but so far no budget yet. Haha!
However, since this could be your first diamond, the safest diamond for you to buy should be Brian Gavin Diamond's because he is a master cutter after all, and he handpicked each Black by Brian Gavin diamond himself. After scanning through the E colour diamonds, I think this will go home with me:
https://black.briangavindiamonds.com/diamon...?a_aid=myengexp (affiliate link) - USD 890 (without shipping).
- Calculated weight is 0.330ct, Actual weight is 0.327ct.
- E VS1 provides sufficient eye-cleanliness.
- Small table, excellent crown height, should provide good fire.
- And that 76% lower girdle should provide big blast of sparks!
Hope this helps?
