Help me compare these two AGS stones

[sna77]

These are both AGS certified.  The second one is the Diamond Quality Document (has 000 grades) and the first one is the Diamond Quality Report, which is less detailed, and used on stones that generally would not score 000, but are still ideal (or near ideal) cut (I think).  

#1 scores a .5 on the HCA with all excellent in all 4 categories….

#2 scores (the 000 Ideal) scores a 2 with only VG in all 4 categories….

Can someone please help clarify this for me?

Thanks!

 

#1. 2.37 E SI1

The second is also an old system AGS0 and might not get AGS0 under the new system.

Interesting diamond.
Misses AGS0 on finish so its a AGS1 which should be a price break with no effect on performance.
The table is larger than most AGS0''s its almost an old school 60/60
Some like that look and some like the smaller table look better.

Biggest question is if its eyeclean which you will need to find out if your going to consider it.
An IS image would be nice but last I heard BN dont offer them.

An option would be to see if one of the pricescope vendors that provides more info could call in the stone for an evaluation and IS image.

Sna77, here is another personal opinion for you: there is nothing utterly wrong with any of these diamonds if the price is right. Although buying a diamond with Tolkowsky proportions (34.5° crown and 40.75° pavilion) is safe, you can still have a great diamond with slightly shallower or deeper crown and pavilion angles.

Some people like Storm don't like slightly shallower diamonds while other find them attractive. Take for example stone A used in this article (33° and 40.6°). Quite a few people at GIA symposium including GIA instructor preferred it to Tolkowsky stone (see e.g. this clip with Maarten DeWitte from Hearts on Fire).

I'm not saying you will prefer it. Just want you to keep your mind open. A few things good about diamonds #1

1. it is listed by different vendors i.e. you can haggle the price and work with a vendor of your choice. E.g. Abazias list it on Pricescope for $24,069 (bank wire).
2. It has good spread: 8.68-8.75 instead of 8.51 i.e. will look slightly larger than the same carat weight Tolkowsky cut stone
3. It has smaller table and same 14.9% crown height i.e. you'll see as much of the stone form the side when it is set as #2 and more than #3 (crown height 13.9%). (some people call it vertical spread and find it important too).

It is very easy to get scared by numbers

- you shouldn't be

Elitist would recommend you to buy only certain type of proportions/symmetry/color/clarity/etc. while in the real live most people won't see any difference or might actually prefer slightly different proportions.

It's also about how you feel about it. If you don't mind paying an extra grand or two for the peace of mind and absolutely "perfect" numbers, then by all means go for it.

I should upload more video clips of comparison on the server. What we saw is that people might also prefer different stones based not only on lighting environment but also clothes (dark or light) and viewing distance...

There are not too many diamonds available in that carat range...

Here is another diamond comparison video clip. Thomas and Myriam Tashey from Professional Gem Sciences are looking at Tolkowski and slightly shallow diamonds.

Hi sna77!

What happened to all of the diamonds on your thread, Who wants to help me find a diamond?? Let me guess, after 3 pages of advice, when you got ready to purchase, the diamonds were sold?

Finding the perfect diamond isn''t easy. When you have a budget constraint, as most people do, it''s all about trade-offs. What happened to the one your brother-in-law (?) took you to see?

Good luck with the search.
