Hi all!
What does it mean exactly when your stone is an ideal cut (GIA)? GIA's highest cut grade is excellent. A stone can be labelled ideal by a vendor, or it could be referred to that because it's cut parameters might fall in AGS Ideal. Does that mean hearts & arrows? Definitely not. H&A is a measure of optical symmetry only--overall cut grade takes much more into account. It is possible to have a H&A diamond that is not an overall great performer. This is rare because if the cutter is going to spend the time to get H&A symmetry, they will usually make sure it gets the highest grade from a lab. There are also a lot of extremely well cut stones that are "near H&A" that just miss in some area, but have exceptional light performance. Does it guarantee excellent light return? GIA Excellent has a pretty broad range and includes some angle combinations that just do not work well together, so no it is not a guarantee. A diamond with a new AGS Platinum report graded ideal has a light performance component, so would be a much safer choice. Does it help hide inclusions and help warmer colors face up whiter? A well cut stone will definitely face up whiter due to better light return. On inclusions, it depends on the type and location of the inclusion.
Appreciate your feedback...![]()

Cut should be the top priority--that is what is going to make the diamond sparkle and shine. Then it depends on your personal preferences. Size? Color? Clarity? Budget? Once you have determined what your wants are, then you can start searching. For instance, it you are wanting the largest size within a budget, I would say look at the lowest color you are willing to go in SI1 or SI2 clarity--as long as the vendor can confirm eye clean. I personally feel that G-H color is a great starting point to guarantee a very white stone. I or J stones can be beautiful, but some people will start to see the warmth in them. Some people like that 'warm white' color, others not so much.
Color is very much a personal preference, with no wrong answer. Have you had a chance to look at some well cut stones in various colors? If you are near a Jared's, their Peerless line of AGS0 stones would give you a good idea, or a Hearts on Fire dealer would also be a good place to look at what colors you like.
Some people have a preference for higher clarity, so their search will be based on their clarity choices. Others want a certain size or specific color. Once again, no wrong answers, you just need to rate your preferences for Size, Color and Clarity and go from there. Which is most important to you?
