    Proportions

    The depth percentage and thick girdle indicates indicates that the cutters' main objective was that of maximum weight retention. A proper 6.5 MM diameter usually goes with with a 1.05-1.07 carat weight. Question is why? Possibilities: Irregular shape diamond rough --- where the final weight would very close to 1 carat, or fall to under 1 carat. cutting away one or more inclusions that if left in, brings the clarity down to SI-2/I-1. Thus, removing them and still getting a 1 carat +, means you have to finish with a wider table facet and a deeper pavillion.
  2. From your video, overall, it looks like a nice diamond. On our computer screen, there appears to be a black reflection at 5 PM. Difficult to tell if it's an inclusion or light contrast due to the camera angle and distance to the ring. If you're happy, that's all that matters.
  3. This is a nice diamond but the 13% crown height combined with the 41.6 degree pavilion is a bit shallow/deep --- which reduces face-up brilliance and scintillation. A better combination would be a 14-14.5% crown height combined with a 40.8-41 degree pavilion angle. Such a diamond combo will refract more light through the top of the stone --- to the point where you would have difficulty telling apart a GIA graded D color from a G color.
  4. Go with #2. Crown angles are similar --- depth percentages are not. The 61.5% depth-preferable to 62.2 and 62.7
  5. IMO, the SI1 is the better cut stone. The VS2 has a shallow/deep crown/pavilion angle combination -> 32.5/41.4 --- which results in a darker center under certain lighting conditions. OTH, the 35.5/41 degree angle combo on the SI-1, combined with the 55% Table percentage, should refract more light up through the Table facet to your eye. The clouds are a non-factor.
  6. What color/clarity grade did the jeweler tell you?
  7. Does this round diamond have a grading report?
  8. It's a nice looking diamond, no doubt. GIA EX-EX standard is a bit broader than the Towlkowsky standard. My comment was directed to the point of contrast. Enjoy the stone.
  9. I believe some of that center darkness you see could be due to the 33/41.2 Crown/Pavillion shallow/deep angle combination.
  10. GIA did a study on the effects of fluorescence on a diamonds' face up color and transparency. Probably the best study ever done on this topic. Here's the link: https://www.gia.edu/gems-gemology/winter-1997-fluorescence-diamonds-moses Medium fluorescence should have no effect on your diamond. And, according to the results of the GIA study, neither should strong fluorescence. As David mentioned, other factors may be at play here. I do have two questions: 1. Was your diamond graded by GIA? 2. What are the specs; i.e., table-depth-crown/pavilion angle, girdle thickness? Did the jeweler give you a Sarine report which shows the cut angle of the facets.
  11. Profile, facing the feather, and perhaps also a top down if the feather is closer to the bezel facet. Good Luck.
  12. If the feather is close to or even slightly shows a break at the girdle surface, it might pose a durability issue. Best for you to talk to their Customer service rep and perhaps get a side view picture to assuage your concern.
  13. #2 will look bigger than its carat weight and certainly bigger than the other two diamonds.
