need feedback asap

[jsal32]

Hello,

I have been reading a lot of info here on PS. I am about to purchase a diamond and just need some feedback before I commit.

The specs are as follows:

round diamond

ct weight: 0.79

cut: very good

color: D

clarity: SI1

depth %: 59

table %: 63

crown: 34.5 (degrees)

pavillion: 40.8 (degrees)

symmetry: good

polish: very good

girdle: thin to medium

culet: none

flourescence: none

measurements: 5.98x6.05x3.55 mm

In the GIA report it says it has a ''cloud'' but no plot to see where it stands within the diamond.



Thanks in advance. I truly appreciate any help provided. Please let me know if I''m missing any info

Hi Jose

The stone has good angles but the table is very large, if you can, look for a stone with a little more depth( 60 - 62%) and table of between 57 - 60%, these along with the angles should give you a pretty stone.

If the cloud is noted as a grade setter ( it will be drawn or noted on the clarity plot, or it will say clarity grade based on clouds) then be wary as these can sometimes impact performance in SI grades.

What are the adverse effects of having too large of a table?

By the way, price on this diamond is $2558

Thanks again. You guys are soo fast to respond I love it.

You get a lot of table glare and can see a dramatic reduction in the amount of scintillation (sparkle) and fire (colored spectral light), because those are a combination of the crown and pavillion facets working together to break up and redirect the incoming light. With a large table, the crown facets are moved too far to the outside of the stone to catch many of the reflected light rays and can't produce the wonderful effects that diamonds are noted for.

Jet has it covered, also read more here on table size. Another thing to watch out for is potential fish eye effect, read more here concerning this.

OK guys one more and I''m out of your hair...promise!!:

The only problem I see is that it has a ''Twinning Wisp'' which might be noticeable and not make it eye-clean??

Thanks,

With the shallow angles on the second diamond, you are very likely to have obstruction issues. This is where the diamond goes dark when being viewed at a close distance because of the available light being blocked--the diamond isn''t able to reflect from a broad enough area of incoming light. The only way to know if it is an issue with the stone is through Idealscope images, which BN does not provide. The other potential issue is whether or not it is eye-clean, as many SI2''s are not.

What about something like this? You can ask if it is eye-clean. Or would you prefer to purchase from BN?

This is a really wierd combo of angles to me. On the HCA it scores well, but I would not buy a diamond with this combo of angles unless I had seen an ideal scope image, which is not possible with BN. Like the first diamond, the table is larger than the depth which I don''t like. As Lorelei mentioned, try for depth( 60 - 62%) and table of between 57 - 60%.

I notice you are selecting diamonds with very good grades from GIA. Is there a reason for this? You really won''t find an ideal cut diamond with that cut grade very easily. Sometimes a top performer is knocked down a grade because of polish or symmetry, but if you really want a great diamond you will need to go up in cut grade.

If you tell us your budget and specs we can suggest diamonds to you

Are you set on BN or are you willing to work with other online vendors?

First off, thank you guys for all of your help. This is one very unique and very friendly forum.

I would ideally want to spend $2000-$2500 and would have to be a minimum of a 0.75ct., eye-clean is a must, at least a G in color, with faint to no flourescence.

I'm trying to get the best bang for my buck... but it seems that I'm looking at the wrong diamonds.

I'm going to look through the JamesAllen diamonds as the one provided by Jet2Ks looks awesome.

Finding the right diamond has been much harder than I expected. The sales guy at RobbinsBros trying to sell me a 0.70ct I1 for $2500 really drove me into doing this. I know I can find better. I just need to relax a bit and look around a little more.

Thanks again guys for your patience with me. You guys ROCK!!!

Why are people suggesting a table of 57-60%? Ideally, the table should be 55-57%.

Jose, here's what to look for:
Crown angle between 34 - 35 degrees (steeper crowns need shallower pavilions and vice versa)
Pavilion angle 40.6 - 41
Table: 54 - 57%
Depth: 60 - 61.9%
Symmetry and polish should be very good (or better).

Because diamonds with 60% tables can still be great stones Laila if the critical angles are within good range, some also particularly like the 60 60 type diamond ( 60% table, 60% depth).
