Hi all,
First time caller here.
To put it bluntly, I have done hours upon hours of research about RBC (round cut brilliant diamonds) as I am searching for a stone for my future fiancée.
I work with numbers all day in my job and naturally, I find comfort in them albeit know their limitations when it comes to the GIA reports.
From browsing Reddit, this forum, multiple websites, the JANNPAUL YouTube channel education videos and then building a spreadsheet to rank diamonds, I have gone quite deep in my search.
My goal is simple: Find the sparkliest (balance of fiery and bright) diamond with the highest carat weight within my budget ($19.5k AUD stone only).
The main reason I have done all of this is because many jewellers in AU who are 'wholesalers' don't carry physical stock and instead turn to their computer and show you stones they can order in for you.
I am now at the point where I may be overdoing it with respect to how 'strict' I am being with the parameters that I have set out.
For context, these are a mix of the member recommended proportions from Pricescope and the AGS 'Bullseye' proportions from the Whiteflash website.
The questions I have are the following:
1. I am aware that even if a diamond meets all of these that it is not guaranteed to sparkle however, do these proportions at least somewhat guarantee a higher chance of a diamond sparkling more, than a diamond outside of these?
2. Would requiring jewellers strictly stick to these proportions be too limiting, and could I be missing perfectly sparkling diamonds outside of these parameters? (assuming some leeway for GIA rounding)
3. I have noticed some diamonds outside of these parameters, still show a nice 8-pointed contrast star in the middle, is this any indication (without looking at the GIA cert) that the diamond already has good proportions and would have good scintillation and brightness?
4. The three jewellers I have requested to find stones for me generally provide a 360 video, sometimes H&A as well as GIA cert and inclusion plot - if I were to buy a stone this way and and ASET scope was not available, would you pass on the stone and find one with a scope image, or use other means to verify?
Thank you all and please be as frank as possible should my requirements be 'overcooking it'.
