Which diamond should I buy?

[Kojack]

I am new here and could use some advice. I am torn between these 2 princess cut diamonds. The diamond will be going into the Ritani Endless Love setting. The second diamond is listed at 300.00 more.

Diamond1

Lab-GIA
Shape- Princess Cut
Carat- .70
Color- H
Clarity-VS1
Measurements- 4.87-4.83-3.33
Depth-68.9
Table-72
Cutlet-N
Polish- Excellent
Symmentry- Very Good

Diamond2
Lab-GIA
Shape-Princess Cut
Carat- .71
Color- E
Clarity- VS2
Measurements- 5.06-4.97-3.49
Depth-70.20
Table- 67
Cutlet- N
Polish- Very Good
Symmetry-Very Good

I was aslo told that the girdle on the first diamond is thick to very thick.Is that good or bad?
Any advice would help.
Thanks!

if these are from the same vendor, have them compare the two and let you know if one performs better than the other.
a thicker girdle on a princess can help it from chipping.

Is it true that most (not all) people cant really tell the difference between a E/F to a G/H? And since the diamonds used by Ritani on the sides and around the diamond are G in color, would the H work just fine?

For me it would... It would be hard to tell these grades apart on alternative centre diamonds, let alone the melee. They''ll just look colorless.

Between the two diamonds, the one thing that can tell them apart at this point is brilliance and the information available doesn''t help with that at all.

Belle is right about chips. ''Very thick'' is a bit much for me, but I wouldn''t mind that too much if #1 the stone doesn''t look way small for its weight because of it and #2 that girdle is not paired with an extremely flat crown.

The setting is a fine one, I wish there were some way to choose a diamond with a nice cut for it. You will get to see these stones and can make that decision (comparing with one that is known for a great cut would help). Without a ton of numbers or light return tests I can''t say anything about that from this side of the screen

Just my 0.2

Like I said, I am very new to this and appreciate everyones advice so far. I asked if the 1st diamond was an ideal cut and this was my answer....

"Yes it is a very well cut diamond. It has the GIA lab report though and not an AGS lab report so I''m not sure how they would grade the diamond. Although some of their ideal cut diamonds get lower light performance than this one."

What do I need to ask for or see about this diamond before I take the next step of purchasing it? I had a pic of the "actual diamond" emailed to me and it looked really nice. What info do I need now though?

Like I said, the diamond is H in color and a clarity of VS1 going into a setting with G colored pave diamonds.

i thought that if you were buying ritani that you had to use a ritani stone?

 

[Kojack]

I thought that too but this dealer reassured me they could do it. So should I be skeptical about this or is it not unheard of to have a dealer do this if you buy their diamond? They said they would send the diamond to Ritani and they would set it, send it to them and then over to me.

 

[lovelylulu]

i was told something else -- perhaps you should call/email ritani and make sure this is acceptable...

From numbers alone, I MUCH prefer the second stone. My concern with the first stone is there is a good chance it will have a low crown and thus not nearly the fire of the second stone. And while a thicker girdle is good in princess cuts, the ideal is TN, TN-M, M, M-STK, and STK. I have never heard of anyone wanting a TK-VTK girdle.

Now, can your vendor provide you with ideal scope images of your stones so you can compare the light leakage? I just have a feeling the second stone is going to outperform the first, making the $300 completely worth it (a better cut AND better color).

 

[researcher]

Also, there will be a visual difference in size between the two stones, with the second being bigger!

 

[Kojack]

Thank you so much for the feedback. So the clarity difference would not really make a difference correct? VS1-VS2 is pretty much the same to the naked eye? I will ask the dealer to provide me with the ideal scope images for both diamonds to compare. Is there any other info I should ask for regarding either stone? I don''t have the crown angle, crown %, pavillion angle, or pavillion %. What does all that info tell me?

 

[Kojack]

I just recieved some more info on both.

.70- H color VS1
crown height- 13.4
pavillion angle- 53.4
girdle- thick to very thick

That is all the info they had on the .70

.71- E color VS2
crown height-11.3
crown angle-37.2
pavillion angle-54.9
pavillion depth-55.9
girdle- 2.7-2.9 medium to slighlty thick
300.00 more

Any more help on a decision would be appreciated.

I also just looked at the ideal scope images of these 2 diamonds and the .71 performed better. The .70 recieved a medium in white light, a high in colored light, and a med/high in Scintillation.

Where the .71 recieved a high in white light, high in colored light, and high in scintillation. Is the crown height of the .71 too low?

As long as your crown is over 10% you're doing well (very well). I'm actually amazed the first stone had a good crown as the numbers didn't suggest it--I guess there are always exceptions to the rule.

At any rate, the performance scores you referred to are actually from a Brilliance Scope, not an ideal scope. Ideal scope images show the diamond in red, black, and white. The ideal scope images will actually reveal more to you about the performance of the stone (its light leakage) than the brilliance scope--IMO.

The info you received from the Sarin (the crown height, angles, etc.) look good for both stones. So, it may just come down to which one looks better to your eyes. Try to get an ideal scope image to post so we can tell you which looks best!

I think that is only a particular setting in the Endless Love line if memory serves me. If not, I''m old and it fails me frequently.

Well, I went with the .71 E VS1. It just looked better overall to me. Now I am in waiting for 4 or 5 weeks until it is complete. I''m sure I will be pulling my hair out the last couple of days before it arrives. Thank you for all the help and input. I look forward to posting a pic as soon as I can.

 

[researcher]

Good choice, Kojack! I can''t wait to see pictures of the stone in the setting!!! I think you definitely made the right choice. The stone will be bigger, whiter, and better performing! Congrats!

 

[Kaleigh]

Congratulations, can't wait for pics. You made an excellent choice!!!

Just one more quick question.... Wht do the symbols really mean on the GIA certificate. The diamond I am looking at has a grading of VS2 but in the symbol area on the GIA it lists that the diamond contains a crystal, cloud, and indented natural. How important are these to look at when buying a diamond. The numbers are good and the diamond looks clean. The symbols listed and shown in red on the GIA show the symbols almost smack dab in the middle of the diamond.IS this something I should really look at? This is the .71 E VS2 as listed above.
