Comparing these two stones??

[johncdbass]

Hello all, I am comparing these two stone. From what I''m readin the proprtions are out of whack. 1.75 VS2 J 57.4 Depth 64 table #2 1.75 VS1 H depth 58.2 table 65. The stones look pretty good to me under the loop but I''m new to this and think that the proportions are wrong. Tried the price scope comparison and nothing comes close. What would these command. Man I''m really tired of this searching. Getting this for 20years married, don''t know if I''ll make it two more weeks, thanks a million, John

Ok... what shape are they? Rounds.. princess... emerald cuts?

I assume you are talking about round stones, If you are than htese stones are flat,and might be fisheye as we call them,depths lower than 59% iwth a lrge table like these have,tend to have that glassy look to them,I dont' recommend them,
try to stay withing these parameters,
d=59-62
t=53-60
grdle=thin-med-sltk
polish vg-ex
symm=vg-ex
flour=n-f
no comments of cr%greater than 35% or less than 30%

stick to these numbers and you will have a nice stone.

Yes they are round. I thought that these dimensions were incorrect. They kind of pass it off because they have a GIA and say if the stones have a GIA then they are great stones. I thought not. I got to tell you that finding a local retailer with good stone and a fair price is almost impossible. Everyone is trying to screw everyone. Its pathetic. Thanks John

Round diamonds are small prisms and the tutorial here contains straight-forward guidelines to what makes their optical properties produce the best light return and an attractive look. With this set of rules in mind I was wandering wether the two were rounds at all... they were not cut with light return in mind.

GIA is great at giving precise color and clarity grades, but does not grade cut. Among labs, only AGS does that, and the AGS0 (best cut grade) stones can be improved upon. However, the logic behind AGS's cut grading is not light years far from what PS considers good crieria for cut quality. However, AGS is perfectly unbiased and PS is a good place to start choosing 'winners' among AGS0 stones, either from the usual sellers here or wherever you can find them

Thanks for your help and great explanations. I recieved a call today regarding the price of the H VS1, with two h color but not certified side stone, with a platinum setting for $14,8. Seems like way too much for this arrangement. I also could get a G VS2 same as above for about the same price, but the proprtions of the G are 55 table and 61.1 depth(other proportions I do not know) Would someone put themselves in my shoes and advise what THEY would do if they were going to buy this ring for themselves. Personally I like to G ring but think the price is too high, again thanks alot John

 

[diamondsman]

what are the size of the side stones? and what size is the center stone? "inquiring minds want to know

"

 

[valeria101]

The proportions of the H stone listed previously does not make me dream about it at all: it is not all that cheap a buy to make all quality concerns an overstantement.

With no info on the size of the sides, there is allot of guess work left. What are those sides? Really small ones could be quite inexpensive. Also, stones around 0.5cts will likely come uncertified...

There is one thing you may want to consider. While each seller will likely set a price difference between a G and a H stones, all things equal, you can get either if shopping around a bit: H-VS2 stones of around 1.7cts get prices from 6500 to 7100 per carat and simmilar G stones from 6800 to 8500. There seems to be some middle ground. These are prices for GIA certified stones. A G with an EGL cert could probably do the trick if the worst that can happen is some uncertainty between the G/H 'GIA equivalent' grading, I supose.

The 'fish-eye' stones you have posted first must have been discounted for their cut... and should have. No idea why they would make an attractive use of money, to be honest.

Thanks again, the sides for the H, VS1, are .45 uncert and are H in color. The side for the G, VS2 are also approx .40-.45 and G/H in color. Both centers are 1.75 with the G having better proportions. Both are listed as good/good in polish and symmetry. John

 

[diamondsman]

Assuming that these are g.i.a stones? GVS2 is more expensive than an HVS1 by about $1,500-2,000.00, I like the depth and table on the G color stone and I think that if the stone does not have A black spot right in the center, or any noticiable inclusion ,that would be the one I would pick.
as far as the side stones are concerned with the GVS2 center ,in platinum I would say that the price should be around $14,500 set and ready to go.
If you were to pick the HVS1, it shoud be around $13,000

check around do your homework and then decide.

John,

Having just completed what you are trying to do, I’ll pass on what I went through as a contribution back for all of the help I received.Hopefully it will help you.I posted the details a few days ago here:

https://www.pricescope.com/community/threads/project-complete-thanks-to-pricscope.13991/

It took about two weeks of fairly intense work.As well, I only wanted ideal cut H&A stones, which my appraiser said command a 10% or more premium at wholesale.

I quickly learned, as did you, that diamonds in the .4 to 1.01 carat range are plenty but diamonds above 1.25 C in the cut, clarity and color combination you want are tough to find.I originally wanted to find an eye clean SI1 G, but realized, although doable, it could take months or I would need to be a little lucky to come across it. After reading all of the tutorials and looking at specs on many of the websites I established a range of acceptable criteria.For me they were: SI1 H or better, ideal H&A cut (perfect H&A pattern not necessary, but desirable), excellent idealscope performance, excellent HCA score (as a filtering tool!), depth above 62%, table in a 55-57% range (to more easily match side stones), good spread for carat weight (looks big for weight), no open feather inclusions on the girdle and a competitive cost/carat price.Once I had my criteria (I had the fortune of having fairly wide budget for the center of $6K to $8K or more for the right stone), I went to work.Of course, I would use judgment in accepting stones that did not fit one of the criteria.However it wasn’t necessary.It was much easier to narrow the choices down and I knew what to ask for.Once I narrowed it down, I asked the vendors to look at the diamonds and give me their opinions compared to other ones they had in stock.I find that the good vendors here will give you an honest opinion.I ended up with a beautiful 1.36 C VS2 H that fit my criteria. The added bounus was it was in the difficult to find 1.3x to 1.4x carat category. The diameter makes it look as big or bigger than non-ideal cut 1.5 carat stones and I did not have to pay the 1.5 C premium.

After I found the center, the rest was easy.Any of the reputable vendors can find top-notch side stones to match in the 0.5 carat range.Settings are personal preference.

I also might add that if one is looking for the perfect diamond at the best price in the world, it won’t happen.If you find a diamond that fits your needs, you should buy it.I have seen several threads where people ask for opinions about gorgeous diamonds with competitive prices and someone tells the originator that they should be able to get it for hundreds to thousands less and to look around.IMHO, forget it.If you’ve done your homework you already know what a reasonable price is. In the carat range you are looking for you could be looking for a long time.

I hope this helps.
