Hello,

I need help deciding a a diamond for an engagement ring. I found a 1.00 ct pear 8.47 x 5.72 x 3.56 d/vs1; 62.2% t.depth; 51% table; no fluor; small to no cutlet; pol/sym both good; girdle slightly thin to slightly thick; pavilion and crown, I don't have exact %s but after looking at dozens of stones and doing lots of reseach I can say they are well proportioned to each other. i.e. the crown isn't to thin the pav. doesn't seem overly thick. The jeweler is asking $6400. My concerns are with the small table and slightly large t.depth. I know the AGA suggest a t.depth of up to 63% for quality cut pears, but I have also heard not to go over 61% to maintain maximum quality. My number one concern is with the cut and minimizing the bowtie effect. Could someone coment on this stone and give me some advice.

Smaller table usually causes deeper stone.

Imagine a cone. If you cut the top too low, the cut area will bee larger and vice versa.

I'm not sure whether 51% table is too bad.

Thank you for your reply.

what do you think about the so called 61% rule. By the way that is another fred c. rule. I have read many negative comments about him on this forum.

Cnuddeje, there are many combinations of diamond proportions that can yield a beautiful diamond. GIA admitted it in 1998 for round diamonds.

Fancy shapes even more complex objects. Playing only by table and depth % is not accurate.

Fixing one of them is pointless. As I shown above, different table size can cause different total depth while all the angles (which are more important for light reflection than depth%) will be the same.

It is MUCH more important that YOU have seen many stones and like this particular one.

The only reason you might not want a deep stone is that it looks smaller for its weight. But I don’t think this is the case.

Hi there,

I would want to see a larger table size that will give the diamond a better light refrection.
You should be able to get a diamond like this for $5400-5900.

Glad to help.
