2.3 on the cut calculator

[mrs k]

Hello,
Is a RB soliatire measuring 2.3 on the holloway cut calculator good?
Any thoughts?

Can still be. Do you have the IS/ASET image of the stone? If not, can you post all the information on the grading report, the information you used for the HCA, and the star and lower half sizes, girdle variation and actual dimensions of the stone.

It certainly can be especially if the diamond has top symmetry and is cut ' tightly'. Do you have images such as Idealscope? That would tell us more. Do you have a copy of the grading report or the report number so we can look up all the info needed please such as depth, table, angles, lower girdle percents etc?

 

[mrs k]

Thanks for your replies

Measurements 6.29 - 6.35 x 3.67 mm
Carat weight - .90
Colour - D
Clarity - VS2
Cut grade - Very good
Polish - Very good
Symmetry - Good
Flur - None
Total Depth - 58.1
Table Size - 63
Girdle - Thin to slightly thick, faceted
Culet - None
Crown angle - 32.5 degrees
Pavillion angle - 40.8 degrees

thanks girls! Did i miss any info that is important?

I am a guy.

Anyway, the table is slightly too big, but it is cut about as best as it can be for that table size. It has a very shallow crown angle coupled with a big table means it is cut more for brilliance and has very good spread for it's weight, meaning a bigger diameter that a more balance cut, but that scarifice fire performance.

So depends on what your priorities are.

Thanks stone cold!

 

[mrs k]

hmm so does that mean it won''t sparkle as much?

 

[Garry H (Cut Nut)]

It depends - what are the proportions?
What do you want to do with the diamond?
as well as the other questions you have been asked.

For example 2.3 could be with a very shallow crown and be OK for a pendant.

 

[stone-cold11]

It will return light well, but fire, which is the ability to produce color lights by the prismatic effect, is reduce.

 

[mrs k]

Thanks Stone Cold.
Hi Garry! I am actually from Melbourne too
It''s my engagement ring actually Where do I find the proportions?

 

[Lorelei]

Basically this diamond is geared more towards brilliance ( white light) than fire ( coloured light) so it might be a bright and brilliant diamond but won't show much in the way of fire. The diamond is also shallow depthed which means it can look large for the weight but its a trade off as due to the proportions you won't have as much fire. As Garry says these shallower types of diamonds are often good for pendants.

Agreed. That type of stone is not to everyone''s taste.
It''ll look bigger and brighter than similar weight stones, but may lack a bit of "life" or "character", possibly making the stone a bit boring.
I would only consider the stone in exceptional circumstances - perhaps if I really wanted very strong blue fluorescence and it was the only one available.

Otherwise, I would find a stone with more balanced characteristics.

Thanks Lorelei
When you say fire what do you mean? I''m very new to this and unsure of this term
I do feel sometimes that my ring looks a bit dull.. even know its a D colour!

Fire is the flashes of coloured light.
Scintillation is the twinkling of white light among darker areas.

[/url] to see examples of fire in diamonds. With the diamond you mention above, it is ' built' with the proportions that it will show more brilliance than fire due to the proportion configuration. So basically it won't show much fire because in this particular case the shallow depth, large table and shallower crown angle all lend themselves more towards brilliance than fire.

Ok thanks!
will check out the fire thread now
I am ok with just brilliance

 

[stone-cold11]

Color do not have much effect on the performance of the stone, so if you choose D color because the SA told you it will perform better, I would go to a F-H color grade and get a better proportioned stone.

Are you sure?

I think that the majority of people prefer diamonds characteristics in the following order:

1. Fire
2. Scintillation
3. Brilliance

Each characteristic is noticeable in different and specific lighting conditions and a diamond is best to have a good balance of features so that it can perform well most of the time.

In my opinion - although it''s a personal taste thing - adding strong fluorescence adds a bit of extra interest in strong daylight, when many diamonds appear almost black.

Agreed.
That stone is over-qualified on colour and possibly also on clarity - and is under-qualified on cut.

I recently had a choice between a similar-weight and similar-clarity F and a D, for a similar price. The F was cut to better proportions, so it was what the Americans call a "no brainer". The clarity was SI1. The stone is GIA 2115300794, 1.02ct, if you want to examine the cert on GIA's database.

I'd improve the cut and drop the colour to F. You might be able to drop clarity into the SI range, but confirm that SI's are eye clean.

Do you have any others in mind? It would be good if you could compare some well cut diamonds in person, for example Jareds sell AGS0 Peerless brand or Hearts on Fire if there is a dealer near you. That way you can see how well cut and balanced diamonds which show a good mix of fire and brilliance behave.

She is in Melbourne, Australia. Don''t think they have Jareds there.. But they have Holloways Diamonds.

Blast - so she is! Scrap that idea then unless you can get to Holloway Diamonds.
