.48 JSi2 GIA

[Equator]

Hi all,

I saw this stone earlier, and thought I''d ask you before making any decisions. It''s a 48 points JSi2 GIA Graded stone. It was graded recently enough. Can''t remember the dates, though... I thought the numbers were more important.

It has Very Good Cut Grade, Very Good Polish and Very Good Symmetry, which I think sounds like what I''ve been reading here. It''s 5.02x3.1mm with 61.1%depth and 56% table with 34.5degree crown and 41 degree pavilion with very small cullet.

With HCA, it scores 1.7 and it''s almost in the middle of GIA''s TIC and very close to the edge of the AGS box.

Please tell me if this is a good/so, so/bad stone, because I can only read the theories on Pricescope, but you all can tell me and describe how it would look to me.

TIA.

What is the girdle measurement please? I would like to see an Idealscope image for the diamond if you can get one.

This link explains about IS, ASET and their uses.

Have you checked it is eyeclean?

Hi, Lorelei.... errmm... no I haven''t checked that it''s eye-clean.

However, here is the girdle measurement: very thin to medium (faceted) 2.5%. The other numbers were 15% and 43.5% near the crown and pavillion angles. 55% next to the table percentage (not the table, but the other number next to it). And 52% near the bottom left. I am ashamed to say that I don''t know the terminology (which is probably why I am asking).

Can you check that figure please? Bottom left is the lower girdle facet measurement on the diamond outline, should be a percentage in the 70's or 80's, see here for example

The other measurements look fine, ask the seller to inspect the diamond if they have access to it to check it is eyeclean to your standards.

I think the numbers look good.

The very think part of the girdle push the cut grade down to a VG. Should not be a problem, especially if it is only at a very small portion of the stone. Check with the vendor if he knows the location and that to take into account of it when setting it.

Do you have the GIA report numbers so that we can double check the numbers online?

 

[Equator]

Whhooppsss... now that you pointed it out, it could have been an 80 or 82%. It was taken by a camera phone, and it turned out rather blurry.

I haven''t checked/asked whether it''s eye clean. But just out of curiousity, how horrible could a GIA Si2 ? Would the Very Good cut/polish/symmetry help much ?

Stone-cold11, did you mean that it should have been and excellent, but the very thin girdle made it only a very good cut ? Unfortunately I didn''t take a picture of the number, because I only took the diamond picture on the bottom of the certificate. I think the jeweller said that it was laser inscribed, though....

Yes it will, very thin will not get Excellent.

Yes, a very thin girdle will not get an Excellent cut grade, a very thin girdle will disqualify it from Excellent. This isn't always a problem as SC says get an experienced person to evaluate it. I thought that was the case with the other number, no worries!

Good and above for polish and symmetry look the same to the naked untrained eye. If the diamond is eyeclean and the proportions work well it could be a lovely diamond, but I would really prefer to see an IS image for that angle combo. Is the diamond with a jeweller and you have seen it in person?

I have a 0.52 K SI2 GIA graded stone which is eye clean and beautiful. However, I once ordered my mom a GIA 0.82 I SI1 for a pendant which turned out to have a black inclusion which I could see. So eyecleanliness is not guaranteed -- something had to make it an SI2 -- but it is likely that the inclusions will not be visible or at least noticeable when set. Just make sure you have a good return policy and you should be fine.

Hi, Lorelei.... the stone is with the jeweller, and as far as I could remember, it was eye-clean. I''d have to check again before I go there and buy it. I needed opinions and assurance from experienced diamond buyers.

I know there has to be something that makes it Si2, but for just under 500, do you think it''d be worth it ? If it is eye clean, and it looks good, should I go ahead and buy it ? It has a good size I think.... I was looking for a half carater because it would reach the 5mm range, but this one does... and the price isn''t bad either, is it ?

It could be a good diamond, like I said with that angle combo an IS would be useful but it probably won''t be possible as jewellers don''t often have access to an Idealscope - but you could ask.

What I would do is check it out carefully away from the store lights to see how it looks, if it performs favourably in daylight and any other lighting conditions you can view it in then thats fine. One thing I would say though, look on the grading report to see if clouds are plotted on the diagram - don''t worry if it says " clouds not shown" in the comments section, what I am concerned with is if the diamond has grade setting clouds or a cloud. Rarely in SI grades these can cause a loss of brilliance so best to get an independant expert to check if that is the case.

Hi, Lorelei... thanks for being patient with me.... I think it said feather on the clarity characteristics. It also said it had an additional inscription with a set of numbers on it (not just the GIA laser). I didn''t really pay attention to it, though..... Could it be a brand ? It surely didn''t look like a date... Just some random numbers of about 8 numbers and had USA at the end of it, if I recall correctly.

Glad to help, thats what I am here for! In that case make sure the feather doesn't break the surface and or is in a non vulnerable area by getting a pro to check it, it is rare a feather is any kind of issue but best to check with SI2. It is likely the diamond has a GIA Diamond Dossier which means it will have an inscription, the GIA DD don't have the clarity plot unlike the usual GIA report, so an inscription is used for indentification purposes. Definitely check but that is probably what it is.

OK.... I bought it. And here is the pic. I definitely can''t see anything under any light and any angle (inclusions). I can see a little colour, but I think that wouldn''t be a problem once it''s mounted.

What do you think ?

 

[stone-cold11]

Looks good. Congrats.

I think it looks very nice! Congratulations!!

 

[Equator]

Thanks, SC and Lorelei....

I am staring at it now... squinting, more like. And I still can''t see a thing. Even with a loupe. I still can''t find the inclusion even with a loupe. It is night time here. So I''d probably see it in daylight tommorrow. Why would GIA grade it Si2 ?

There is also a comment on the stone that it has an extra laser that says LK (which after a research, I found that it stands for Lazare Kaplan). The certificate did not come with the ring (to which it was mounted), but rather, it was graded after it was taken off the ring. I couldn''t find any marks on the surface either.

Any opinion on this ??

Grading is subjective, some graders are harsher than others and this clarity grade is not created equal, some SI2 are extremely clean to the eye.

 

[joelly]

Good find Equator!!! Congrats!!!

 

[stone-cold11]

If they want to grade it SI2, but it is a VS2 then you got a great deal. So why bother trying to think why it was graded a SI2? If you really want to know, send it to an independent appraiser and ask him his opinion on the clarity and ask him to show you how to spot it?

[MichelleCarmen]

Pretty stone. Congrats on finding it for such a great price.

 

[Gypsy]

Wow that''s a pretty stone at a nice price, congrats.

 

[Equator]

Thank you, Lorelei and SC for being patient with me during the buying process. SC, you''re quite right about not worrying why it''s a SI2. It would be very silly indeed.

It''s a very nice stone, and yes, I''m very happy with it. So thank you, Joelly, D&T, MC, Gypsy I''m going to enjoy this for a lonngg lonngg time.

It suprisingly matches my 54pointers well. In my other thread, I bought a 54 points JVS2 (diameter 5.23mm), then in the quest to match that, I got a 59pts IVS2 (diameter 5.47mm). And even after some of you has advised me that it would be fine to put these into a pair of studs, I wasn''t quite sure, and I thought I''d wait. I didn''t mean for this 48 points to match the 54 points, but when I put them side by side, they look fine (this one is 5.02mm).

My jeweller might be getting a 50points GIA ISi1 soon. Should I wait for that, and just pick the best matching pair or should I just go ahead and make a pair of the 54 points and the 48 points ? It''s been almost 5 months since I''ve wanted this year''s blings done. But I don''t mind waiting a bit more.

Here is a not so good picture of the three just to give an idea.

 

[AprilBaby]

Gorgeous find!

 

[stone-cold11]

Wait? See what he can get you, maybe you like it more?

If you don''t mind waiting a bit longer, then see what he comes up with.

 

[tyty333]

That is a beautiful stone! Congrats! What are you doing with all these stones...I know one pair for earrings what about
the other/rest? Or are you just a collector of pretty stones that are good deals

?

 

[Equator]

Hhmmm... with your support, I shall restrain myself and wait for the 50pointers, SC and Lorelei.

Thanks, AprilBaby, I love these three. I also have a small 40 pointers with the similar cut quality that I love.

tyty333, it all started with one stone for a ring (the 54 pointers). Then I thought about a pair of studs, so I bought the 59, but they didn''t fit. And then the diamond bug bit me, and now I have all these lose stones that I couldn''t help buying. One day I''d wear them all. But now they''re sitting in their little pretty boxes.

I still owe myself a marquise ring (already had a stone, and then upgraded it once), and a pair of studs. But I was thinking that since I have all these stones, I might do a set of matching ring (59), pendant (54) and earrings (48 and it''s other half that I have yet to find).

Anyone has done a whole set of matching pieces ? Please post pictures if you have.
