Hello all,

So I have been trying to learn as much about diamonds over the last several weeks and have really just begun going in circles now. I was out looking at some diamonds today for an engagement ring and found this diamond:


Measurements 6.92 - 6.96 x 4.20 mm
Carat Weight 1.23 carat
Color Grade H
Clarity Grade SI2
Cut Grade Excellent
PROPORTIONS

Depth 60.6 %
Table 56 %
Crown Angle 33.0°
Crown Height 14.0%
Pavilion Angle 40.8°
Pavilion Depth 43.0%
Star Length 50%
Lower Half 75%
Girdle Medium to Slightly Thick, Faceted, 3.5%
Culet None
FINISH

Polish Excellent
Symmetry Excellent
FLUORESCENCE

Fluorescence None
CLARITY CHARACTERISTICS

Clarity Characteristics Feather

How this is SI2, I am not sure as it looked eye clean to me. Here is the cert number if interested in the inclusions plot: 2136856926.

I am looking to put this on a split shank lucida style band, ala Tiffanys.

At first I had my heart set on finding a 1.5 carat stone that fit my desire for performance and price but I have been having a very though time with this. I saw this diamond today and I thought it might be the one. My indecisive side needs a little moral though. Thanks so much!
 
Keep in mind a lot of S12's ARE eye-clean. I have one. But those inclusions don't seem to be S12. More like VVS2....
 
Dangerous advice being given. Tread carefully here. Cleaner plots at SI2 for such sizes equates to higher chances of having problems. Either the feather is obvious (for e.g., being colored) or it poses a durability issue. It isn't graded as an SI2 without reasons.
 
Yup. That's likely to be one big bad feather that breaks the surface and poses durability risks.
 
Thank you very much for the replies. I'm a little disheartened, but I would definitely rather know these things sooner than later. Assuming that the diamond is eye clean (I couldn't see anything, but I am by no means an expert) is there a way to further assess for durability? Would GIA give a SI2 and above stone such a rating if they were liable to break? Should I walk away?

I am not giving advice, I am not a gemologist. Just saying what it looks like to me. :)

Possibly. Ask the jeweler why its SI2. If the salesperson or jeweler can't tell you why, I would move on. There are tons of other diamonds out there available. It just isn't worth the effort and costs to get it send to another appraiser for an evaluation.

Have you seen it under a loupe?

The jeweler said that they own their own diamonds, and as such they buy the best. This is opposed to other jewelers who don't necessarily own the diamonds they show I guess. The person who does their buying is GIA certified (not sure how unique this is). I did look at it under the loup and had to try to hard to find the inclusions, but this is maybe my 7th or 8th time looking in a loup. I wasn't assessing whether these inclusions reached the girdle/surface as I wasn't thinking about durability being an issue at the time. Thank you very much for the comments!
 
As a vendor I do not want to get into the trap of analyzing another vendor's diamond, but I do want to make a comment.

You are not a professional, there is no way you are going to see what you need to see with a loupe and the jeweler should know this.

Ask him/her to show you the diamond through their microscope. If they do not have one, I recommend you find another jeweler. I have done this for a living since I was in my late twenties and I do not use a loupe for analyzing the fine details of a diamond. A good microscope is a critical part of my gemological equipment and is much more important to me than my ASET or Idealscope or a Sarin will ever be.

If they do not have one, they are not coming anywhere close to providing you what you need to be able to see these things for yourself.

Caution: These are just the cranky thoughts of a vendor doing paper work on a Sunday when he would rather be fishing...

P.S. I am 66 now, but my eyes are still in excellent shape. There are a gifted few people in the world who can do all they need with a loupe, but they are a very small number of VERY LUCKY people. In spite of doing this for most of my adult life, I am not one of them, not even close.
