Hello everyone,

First time poster and total diamond newbie here and I would appreciate your honest advice.

I just bought a diamond from a dealer last Friday for a pending engagement. The stone's cut, polish and symmetry are all excellent as graded by GIA. It is a G, VS2, 0.74 carats. The stone is hearts and arrows.

I only learned of the HCA tool after buying my diamond. I plugged these values in per the GIA cert:

Depth: 60.9%
Table: 60%
Crown angle: 32.5%
Pavilion angle: 41.4%

The result was an HCA score of 3.6. As this is above 2, should I return this stone?
I guess what I'm asking is, when a stone in the 2-4 range is considered to be "very good," is it worth keeping?

In a room with ordinary lighting, the diamond seemed to shine brilliantly relative to another I was comparing against.

Also, I'd appreciate any analysis or general commentary about the purchase. I just want my fiancee to have something great.

Thank you kindly.

Who said your stone is a H&A?
 
Hello Sakuracherry,

On the wholesaler packaging, it was listed as H&A. I forgot to look at it through the viewer before I left the appointment, but the dealer told me to go back and see it through the viewer so that she could show me the H&A. I know GIA wouldn't have it on their cert., so I need to verify but my dealer has shown herself to be trustworthy thus far.

please post a pic of the hearts.
 
Most decently cut stones will have a hearts and arrows image, that however does not make them a hearts and arrows stone. HCA judges pav angles higher than 41 severely and that is probably why your stone didn't score well. Did you have an opportunity to view your stone next to others EX cuts with different proportions? Is it possible for you to receive and idealscope image of your stone?
 
Thanks Christina and Dancing Fire. I do not have more pictures at the moment or the idealscope and this is all the information I have for now. Would it make a huge difference if it was a true H&A for the purposes of light return?

Thank you.
 
HA is optical symmetry not light performance, so it's possible to find a non HA stone that out performs a HA stone, but having both superior light performance AND optical symmetry is very important to some people and not so much to others. The question here is about a stone being sold to you with the impression that it is a TRUE HA stone and you paying a premium for that. If they want to sell it to you as HA, then they need to back that claim up with more information and or documentation.
 
Thank you for the helpful resources Christina.
