PLEASE HELP!! Final choice!!!!!

Recommended Posts

Hi,

 

Looking for your thoughts on 3 diamonds. I’m at the last stages of picking so one of these will be my final choice.

 

For a bit of insight, the most important thing to me is cut. Clarity and colour I’m unsure what i prioritise although I am sure that I do not want a stone that is not eye clean nor a stone that looks noticibly yellow/ warm/ tinted in platinum setting.  All 3 diamonds below have a bit of a trade off.

 

Firstly, we go for the 1.05ct J GIA ideal cut, SI1 stone. This has been confirmed as eye clean and no green tint no brown tint and not milky.  It has medium flourecence. It falls in to ‘ideal’ cut grade with AGS and score 2.2 on HCA. In the comparison picture this is the stone in the bottom left corner. It costs £3,470. It is the cheapest stone but my main concern is it may look more yellow tinted/ warmer than the other stones. It looks that way from the comparison picture I attached but also don’t think it is a fair comparison as they are all in different background so is this making the other J look more whiter than this one?

Next up is the 1.07, J, VS1, GIA ideal cut, medium flourecence, confirmed as eye clean and no brown tint no green tint and no milkyness. This costs £3770 so £300 more expensive than the first stone. To me, in the comparison picture attached (this stone is bottom right) it looks more whiter than the first J. It looks significantly less warm, is this possible or is it just a trick of the light and more related to the background as 1 J has a grey background and the other has a blueish background? This diamond scores 2.3 in HCA calc But Falls in to ‘very good’ cut category in AGS (ie 3 from the top as it goes ideal, excellent then very good)

Thirdly, is the 1.06 I coloured SI2 gia ideal cut diamond. This is confirmed as eye clean with no brown tint no green tint and no milkyness. No flourecence, it scores 1.5 is HCA calc and falls in to ‘ideal’ cut catagory with AGS.  My worry here is if the generally more inclusions and the cloud on diagram on table will dull diamond and affect brilliance. It costs £4200 which is £700 more than the 1.05 J. this diamond Again, to me, this stone looks less warm than the First J (but is there a significant improvement in colour and is this just because of background used??). This diamond is top left in the comparison picture I sent which compares all 3 at same time. Main concern here is that is is SI2 (although confirmed as eye clean I worry that general inclusions will dull diamond and brilliance)

In summary 

 

The 1.05 J my main concern is colour/warmer tint/ visibly yellow.  Could this be significantly more warmer than other diamonds (both a J and an I) or is this just because the background isn’t comparible (ie some diamonds on a blue background some are on grey).  Do you think this will be noticibly yellow in platinum?

 

The 1.07 J, my main concern is Cut. It drops down 2 AGS grades in cut although it is still GIA excellent. It upgrades to VS1 clarity but not too bothered as all 3 eye clean. Is the downgrade in cut worth potentially having the less warm diamond compared to the previous J.  (if this actually is less warm on not a trick of the background, but how would I ever know?).  It is £300 more expensive than the other J.

 

The 1.06 I colour SI2 ideal cut diamond. My main concern here is clarity. Will there be a really big colour difference moving from J to I that would justify dropping from SI1 to SI2. This is £700 more expensive than the 1.05 J and also a slightly better cut than this but my concern is that other things going on in the SI2 such as clouds etc could ruin the brilliance and light performance and sparkle of the diamond anyway. Would you drop a clarity grade to go up 1 colour grade and would this affect brilliance? Would there be noticible colour change from J to I, ie going from noticing the yellow warmness in J platinum to not noticing it in I platinum? 

 

What would you think is the best choice? Sorry for large message but the end is near!

 

Thanks

Thomas

Couple of points - I think I have already given you feedback on all of these stones, so I'm not going to repeat this, but I'll focus on a couple of technical aspects:

1. Cut grades

gia ideal cut diamond

No such thing. That's Blue Nile's marketing categorisation which means "I want to sell you this diamond". If what you are using to determine "AGS" cut grades are the plots on the HCA app, then these are no longer relevant; AGS have changed their grading system at least twice since those tables were published, and the current AGS grading system is quite different from having a single set of parameters and measuring "distance" from those.

2. Clarity and effect on transparency

No they would not. There are (relatively rare) SI2 diamonds where the clarity grading is due to clouds or wisps - not simply "there is a cloud in this diamond" - where the overall transparency of the stone is compromised. 

The call on transparency is one you need to make with your own eyes (or at the very least photos and video) - no lab grades it, even in the extreme case of (I1), I2 or I3 diamonds, where the inclusions are deemed so prominent that they may affect transparency and brilliance - note the "may" rather than "do". And I have seen plenty of I1 diamonds where the inclusions do not affect transparency or brilliance, even though they are obvious to see, at times even with the naked eye.

3. Colour grading

25 minutes ago, Tomdiamond said:

I think what we are seeing is not so much a change in background, but in camera equipment and (especially) white balance setting. Which is why judging colour from photos is generally a thankless task, and judging colour from photos taken by unknown photographers using unknown equipment set up in an unknown environment and configured with unknown settings and post-processing is an impossible task.

It is so variable on the individual observing and the circumstances that it is impossible to answer this in a certain way. Generally speaking, J-K is where people start noticing warmth in a significant way. However, a really well cut J-colour diamond can still look white "on its own", and platinum is more forgiving in this respect than rhodium (but less forgiving than unplated white gold). It all depends on what you want to "buy insurance for".

Of these 3, ignoring price, my recommendation is to go with the 1.06 I. It's better cut than the other 2, it is clearly the least tinted and even though the inclusions may be easier to see they are not (to my eye and in as far as it can be seen in the video) unpleasant even though the main one is reflected 8 times! Whether the extra cash outlay is burdensome, only you can judge.

Thanks for your help once again. I’m down to the 1.05 J and 1.06 based on this so just have to justify if the £700 outlay is worth the benefit.  Thanks again
