3 carat Round Opinion

[longwood50]

I appreciate all of the advice. I am still a novice but starting to pick up on a few things. I am the person looking for a 3 carat round brilliant excellent cut. One of the posts talked about HCA and how one stone with an excellent rating would be a brilliant stone. I notice that most of the stones do not contain that grading. The following stones are two that do. First, what is the opinion of these two stones. Secondly how is the HCA rating determined and who does that. How can a person realistically know what the HCA grading is since neither the GSA or GIA do that? Thanks in advance.

You can calculate the HCA yourself. Under the Tools tab above, the first choice is HCA.

Holloway site on the HCA and how it is developed. Methodology in the method link.

I would be very wary of SI stones in 3 carat size. Garry Holloway has they will rarely be eyeclean at that size. You'd need someone to call in the stones and take magnified images as well as idealscope images for you.

Is this stone for yourself or for someone else?

Okay, that is good because you can assess the color and clarity that is comfortable to you. There are going to be J SI stones that are better and worse than others, and it is good for you to be choosing it for yourself.
