newbee5 :  FYI, “ideal cut” is not a term used by GIA or IGI (to my knowledge, only AGS uses this term to describe cut grade), so if it is the jeweler who simply told you that it is an ideal cut, that is just his opinion and a marketing term they use to sell diamonds (much like Blue Nile’s Aster, etc).  AGS ideal cut parameters are very tight, even tighter than GIA excellent cut parameters, and without a copy of the specs shown on the grading certificate there is no telling if it is actually “ideal cut”.  I think the most important thing is to get a copy of the grading certificate so you know what you actually have.  Diamonds graded by IGI (and those other lesser known labs) typically retail for less than those graded by GIA and AGS, so if it’s not graded by GIA or AGS I hope the price reflected that.

Excellent and Ideal would be in the same category ..if her jeweler said it’s an ideal cut then her GIA cert would say excellent

ringclique :  I beg to differ.  Ideal cut grade is used by AGS to describe very specific cut specs.  GIA excellent cut grade also includes specific cut specs, but a much broader range.  As such, although a GIA excellent cut grade might lie within AGS ideal cut specs, it does not necessarily equal an AGS ideal cut grade.  

Also, contrary to what I stated above, IGI also appears to also use the term ideal for its highest cut grade; however, their ideal cut specs are much broader than even that of GIA.  My apologies for the misinformation, I am not well versed in IGI.  Think of it as a target with IGI ideal cut specs being the outer ring, GIA excellent cut grade specs being next, and AGS ideal cut grade specs being the center.  OP, if you decide to go with an IGI graded diamond I would suggest you look into the specs for GIA excellent cut grading and at least shoot for a diamond within those limits rather than relying on IGI’s ideal cut grade.

ringclique :  No, that is incorrect.

Excellent cut is a GIA term. A true ideal cut is an AGS 0, and it has been evaluated for light performance. An IGI ideal has not been evaluated for light performance, and should be sold at a price point lower than either GIA or AGS. Expect to pay a premium for an AGS Ideal 0.

newbee5 :  I’m so sorry newbee5…I didn’t realize this is a lab created diamond.  It is almost guaranteed to be IGI graded. GIA does grade lab diamonds but not many so it is very highly unlikely that it is GIA graded.  And AGS only grades mined diamonds.

newbee5 :  I know that GIA grades lab diamonds but not in the same way as they do mined diamonds, as far as cut is concerned. Color and clarity grading is comparable. AGS does not grade lab diamonds which is unfortunate. If you could find a lab diamond with a GCAL report that would be best. They’re not as well known, but GCAL is a reputable lab.

ringclique :  Lol. They’re counting on you to be confused! When it comes to diamonds and jewelry, companies play fast and loose with language – and the truth. Look at all the ads for “man-made diamonds” or “lab-diamonds” that are really just cz. As a consumer it pays to educate yourself. Or, as the saying goes, believe half of what you hear and none of what you read lol.

Mine is a J. It’s set in rose gold. I notice a more steely grey in some lights, but never a yellow tint. I wouldn’t trade it for the world! And yours is stunning. Here are two photos in different lighting conditions. newbee5 :
