Do you think 1.01 ct G/ SI2 will have obvious inclusions?

Hi
Looking at a Princess 1.01 G / SI2. The clarity is starting to get a little over the top for me but, I am planning on viewing the diamond in person to be sure. Anything in particular I should be looking for. Its for a ring. Thanks for your input.

There are lots of eye clean SI2s out there, you need to see it in person to determine whether or not it is eye clean to your taste, or have an experienced vendor look it over for you. With inclusions, the only thing to watch for is when a cloud is a grade making inclusion, which can sometimes affect the optical performance (I believe, Lorelei has written about this before and may reply here shortly). No need to worry about "additional clouds not shown", only ones that are grade making.

Do you have an ASET image or a photograph of the diamond? Those tools will help us tell you if it is a good cut or not, but with fancies, ultimately you need to see it. AGS now offers cut grading of princess cuts, and for my money, I would look to purchase and AGS0 princess cut to make sure I was getting the best light performance.

Spot on Dreamer, saved me a lot of typing! The other time to worry about clouds is if it says in the comments section " clarity grade based on additional clouds not shown" that could be an issue so check such diamonds out carefully. Also see if you can check the diamond out away from the store lights as inclusions can sometimes pop out more in some lights than in others.

Thank you.
I know from my time spent learning on this site, that Idealscope and Asetscope are the best ways to determine cut performance, but, I am dealing with a smaller rural retail store and they don''t seem to endorse these tools - not because they are in any way trying to deceive me, but they haven''t yet made the move to this new "technology." They insist that there is no international standard grading system for the princess cut, and I guess, to a degree, they may be correct.
I am going to have to rely on my personal inspection / opinion of the diamonds. I have been comparing table/depth.etc to the AGA charts - don''t know if this is worthwhile or not.
Thanks for your help.

As I mentioned previously, AGS has developed a standardized method for grading cut in pricess diamonds, so you can always ask your retailer to call in some of those diamonds for you to view.

Also, the IS and ASET are not *required* to assess the cut as long as you can a) see the diamonds in person b) compare a number of different diamonds that vary in their angles etc (ideally including an AGS0 pricess) and c) can take the diamond for a "test drive" in many many different lighting environments -- store lighting, natural diffuse lighting (under a tree for example), bright sunlight, spot lighting, dim lighting (under a table for example).

Absolutely - ditto Dreamer. Also you can buy an ASET scope to take with you, it will work on any round or fancy shape diamond and you have it for future purchases! This tutorial explains about ASET and its use.
