  1. There are a few issues to consider here. The first has to do with the grading reports. GIA is the most consistent and consumer protective (accurate) grading lab while the IGI is a little less so. The IGI in New York tends to be quite accurate but the one in Belgium (where this stone was graded), tends to be a little lenient. I would guess the VVS grade if close enough that the stone runs no real risk of being imperfect but I may not be as sure about the color. If you were to put these two stones side by side, I would guess the IGI graded stone would appear darker and might have come back as an I color from the GIA. This is pure guess work on my part, but it is an educated guess based on 30+ years of looking at these reports. The second flag is the make or cut of these stones. The GIA stone has a fairly large table (61%) by today's more 'ideal" standards and the crown angle is quite shallow (32.5°). The advantage is that the stones spreads larger, which is what you were looking for, but the downside is the stone is likely to appear shallow and lifeless, or at least not as brilliant. Here is a search for similar stones within your price range: I hope this helps
  2. As you start working with a vendor or two, especially online, ask for comparative videos. Videos with several stones next to each other in a live or real environment as opposed to individual clinical vids taken with differing methods that really don’t allow you to compare them at all.
  3. The other difference between #1 and #2 is the length to width ratio. The first is a 1.03:1 ration which appears square. Anything below 1.05:1 will look square. The second is what I call off square or a fat rectangle. There is no right or wrong, just a matter of personal preference.
  4. Based on your thread title, I would lean towards #2. It is a little bigger looking (6.94x6.44) as opposed to the first one (6.65x6.43) and it saves you a little money. I am not partial to the faceting pattern on the third stone as it looks too busy from face up. The faint fluorescence on the second stone will help the price without affecting the look of the stone in any way. Hope this helps,
  5. What is this? Real or Fake?

    It’s very hard to determine what this is from the pictures. What is fairly clear is that the setting is silver (925 stamp) and the stone does not appear to be a diamond. Based on the look and the apparent wear on the stone it could be topaz or moonstone or any number of other semi-precious stones. The best way to find out for certain would be to bring the ring to a qualified gemologist. I hope this helps.
  6. Pear Shaped Diamond

    At first glance this stone looks like a great candidate. I like the shape appeal and the stone does not appear to have any significant bow tie. I would not be concerned with the feather as if you look at the diagram closely, you will notice the feather is a minimal player in the plot. There are more needles which are internal and don't have the potential negative impact of feathers. That said, feathers in an SI1 are usually nothing to even think twice about unless they are visible. My bigger concern on this stone are the two black needles/crystals on the edges of the stone. They are probably nothing to worry about but as at least one of them seems to reflect, I would examine the stone very carefully to make sure it is clean to the naked eye. Fortunately you have a robust return policy to rely, just in case. On the off chance you reject this stone, keep in mind there is very little discernible difference between an E and an F and between an F and a G. You could, for similar money, consider a GVS2 and essentially eliminate the clarity concern without giving much up on the color side.
  7. Which heart shaped diamond would you choose?

    This is exactly where a comparative video of the 5 remaining stones would really help with the decision. Apart from the SI1 with the prominent black crystal inclusions, the other stones are difficult to differentiate while they are presented in their own bubble. What we do in cases such as this is line the stones next to each other and shoot a short video. Side by side, it is much easier to see which one you prefer over the other. It's worth asking.
  8. 1.71 carat RB, I/VS1- good purchase?

    The reality is that there is a slightly wider range of acceptable numbers that will still give you a gorgeous diamond. This stone will most likely be stunning. Have you searched the DiamondFinder on this site to make sure the price was competitive? Here is a link to the search:
  9. The pictures seem to have been taken by at least 3 different methods or sources. #1 and #3 from source A and the two others from different sources as well. this makes comparisons more difficult. That said, #2 has the best H&A images of any of them and I suspect would be the stone with the most fire, scintillation and contrast. Ideally I would ask the vendor to put all 4 stones side by side and get you a real comparative image or video. #1 and #3 have a dead ring just inside the table which is apparent in all images. #4 has an inconsistent pattern which may be due to poor photography or more likely due to symmetry issues.
  10. Dark Blueish-Gray diamond color?

    I don't believe so, no. It does not get rid of color, it just dims the intensity.
  11. Dark Blueish-Gray diamond color?

    I started the reply below a while ago and forgot to post. Davide beat me to the punch, of course.... Interestingly, when dealing with fancy colors, the last thing you want is an ideal cut stone. Ideal proportions maximize the light return, sparkle, scintillation and fire coming from the stone. Basically, the closer to ideal, the more you will see reflected light rather than material color. When shopping for an ideal cut diamond, it is not unusual to opt for a slightly lower color stone as the reflected light actually makes those stones look whiter than they are. In a fancy colored stone, most manufacturers will look to deepen the body color by deepening the pavilion or crown, or both. Ideal cut and natural color are counter productive. The better the cut, the less you see the body color.
  12. VS1 or VVS1

    Both stones are gemologically gorgeous. In this case you really can't go wrong either way.
  13. Some feedback please

    To add to Furquan's reply, I believe the thick girdle, very steep crown angles and greater than desirable depth will most likely result in a stone with a fairly dark center. Will is sparkle? Yes, but most likely not as much as a better cut stone. But as Furquan alludes to, a better cut stone of the same wight will cost more. A better cut stone of the same diameter, will weigh less, and thus you may save money for a similar visual size.
  14. Is this diamond or flourite ?

    Those are garden variety quartz crystals. Edited to say: Sorry. Those are just quartz crystals. There is such a thing as garden quartz and these are not that. This is a garden quartz crystal:
  15. Oval diamond, K colour, 0.51 carat VS2

    I noticed this too but had not thought of the rose gold angle.
