Blue Nile Canadian Diamonds Review: 6 get the Nice Ice Stamp of Approval

Blue Nile has one of the most extensive selections of Diamonds from Canada, but finding Canadian Diamonds that meet my selection criteria can be a bit of a challenge. I was helping a client find a very specific diamond today, and in the process ran across a few viable options and thought that a Blue Nile Canadian Diamonds Review might be in order… After all, if one person is asking me to look at Canadian Diamonds from Blue Nile, the odds are that lots of other people are also. By the way, I got the idea for this picture from a banner that Brian Gavin Diamonds ran a few years back, I even used one of their diamonds to make the eyes, they’re probably going to kill me, but I couldn’t help it 😉

It’s like the line from the old Abbot and Costello movies “I’m a bad, Baaaad boy!” but even Brian Gavin knows that the most sincere form of flattery is imitation – right buddy? And it’s not like they have a lot of Canadian Diamonds in their inventory at the moment, those little suckers are hard to come by these days! In fact, I only found a few within the Blue Nile inventory of Canadian Diamonds that met my selection criteria, so let’s get down to business and review the few that did:

Blue Nile Canadian Diamond Review #1:

This 0.70 carat, F-color, SI-1 clarity, Canadian Diamond from Blue Nile is graded by the GIA with an overall cut grade of Excellent, which is the highest rating available from the GIA. With a total depth of 60.7% it has exceptional spread, which translates to a slightly larger outside diameter, which gives you more surface area to look at for the carat weight. The table diameter is 57% and the crown angle is 34.0 degrees which is a good offset for the pavilion angle of 40.8 degrees, this diamond should exhibit a lot of brilliance! This diamond is actually part of the Canadian Love Diamond collection, as indicated by the inscription that appears on the girdle edge of the diamond. According to the Canadian Love Diamond web site, they produce hearts and arrows diamonds, but without a photograph of the pattern of hearts and arrows, I have no way of verifying that claim. But the characteristics of the diamond look promising, it is cut to a combination of proportions that is known to produce great light return.

Blue Nile Canadian Diamond Review #2:

Next up we have this 1.06 carat, H-color, VS-2 clarity, Canadian Diamond from Blue Nile, is also graded by the GIA with an overall cut grade of Excellent. It has a total depth of 61.8% with a table diameter of 56% and a crown angle of 34.5 degrees which is a good offset for the 41.0 degree pavilion angle, which is just one tenth of a degree off of the 40.9 degree mark which is the upper crust of my preferred range of 40.6 – 40.9 degrees which represents the “sweet spot” for pavilion angle… now the range of pavilion angle for the zero ideal cut rating is much broader than my preferred range, so a tenth of a degree is not a really big deal, but it would be if the crown angle were much steeper – so it works in this particular instance, but it is something which needs to be considered on a stone-by-stone basis.  This diamond is inscribed with the Canadian Maple Leaf logo, signifying that it is a Canadian Diamond, and the inclusions meet my selection criteria…

Blue Nile Canadian Diamond Review #3:

This 1.28 carat, I-color, VS-2 clarity, Canadian Diamond from Blue Nile, has an overall cut rating of GIA Excellent, and has a total depth of 60.8% with a table diameter of 57% and a crown angle of 34.5 degrees which is offset by a pavilion angle of 40.6 degrees with a medium to slightly thick, faceted girdle and no culet. The proportions are well within the spectrum which I’ve designated as my preferred range of proportions, and represents the center region of the range designated for the zero ideal cut proportions rating, it’s like hitting the bulls eye on a target! This translates to superior light return… the inclusions look fine. The diamond is inscribed on the girdle edge with a symbol of the Canadian Maple Leaf, indicating that it is produced from diamond rough that originated from Canada.

Blue Nile Canadian Diamond Review #4:

This 1.51 carat, I-color, SI-1 clarity, Canadian Diamond from Blue Nile, is graded by the GIA with an overall cut rating of Excellent, and has a total depth of 61.8% with a table diameter of 56% and a crown angle of 34.5 degrees with a pavilion angle of 40.8 degrees and a thin to medium, faceted girdle and no culet. It is cut to the parameters of Tolkowsky’s Diamond Design, which means that the proportions of the diamond are optimized for maximum light return. Now the plotting diagram of the diamond provided on the GIA diamond grading report, might look a little busy, but realize that all of those little dots represent tiny little diamond crystals which were trapped within the larger diamond crystal as it formed, diamond within diamond, no big deal… I’d much rather have a bunch of tiny diamond crystals running through the body of a diamond, than a bunch of feathers, knots, twinning wisps, or cavities, which might actually pose an issue to the durability of the diamond. Once again, the Canadian Maple Leaf logo is inscribed on the girdle edge of the diamond, which indicates that the diamond is  produced from diamond rough that was sourced from Canada.

Blue Nile Canadian Diamond Review #5:

Now if you’re looking for something a little brighter and whiter, this 1.53 carat, E-color, VS-2 clarity, Canadian Diamond from Blue Nile is the ticket! The diamond has an overall cut rating of GIA Excellent, and a total depth of 61.6% with a table diameter of 54% and a crown angle of 34.0 degrees which is offset by a pavilion angle of 41.0 degrees with a thin to medium, faceted girdle and no culet. Now if you’re familiar with my preferred range of proportions, you know that I like to see the crown angle of the diamond between 34.3 – 34.9 degrees, offset by a pavilion angle between 40.6 – 40.9 degrees, but you might have also have noticed that I frequently indicate that other combinations work perfectly fine… this is one of those instances, the slightly shallow crown angle is a perfect offset for the slightly deep pavilion angle, and the E-color of the diamond is going to give it a little extra POP, so it’s all good!  In terms of inclusions, there are only a few diamond crystals and needle shaped diamond crystals, everything looks great! Once again, this diamond is inscribed with the Canadian Maple Leaf symbol, indicating that it is produced from diamond rough that was mined in Canada.

Blue Nile Canadian Diamond Review #6:

All right, the last Blue Nile Canadian Diamond which I found interesting, is this 1.62 carat, G-color, SI-1 clarity, Canadian Diamond from Blue Nile, which has an overall cut rating of GIA Excellent. This diamond has a total depth of 60.5% with a table diameter of 57% and a crown angle of 34.0 degrees, which is offset by a pavilion angle of 40.8 degrees and a thin to medium, faceted girdle with no culet. Once again, the 34.0 degree crown angle is a little shallower than I prefer, but the volume of light return is going to be off the charts because of the 40.8 degree pavilion angle… the crown angle primarily controls the type of light return, in this case, if I were to guess, the diamond will exhibit a little more brilliance than dispersion, but I’m not so sure that the average person would notice without a great deal of coaching, and probably another diamond to compare it with… what they would see, is a diamond that is reflecting an incredible volume of light, and a lot of icy, white sparkle! Naturally, the inclusions meet my selection criteria, everything looks good… and the diamond is inscribed on the girdle edge with the Canadian Maple Leaf logo, indicating that it is cut from a piece of diamond rough that originated in Canada.

This concludes my review of Canadian Diamonds from Blue Nile, the diamonds referenced above meet my selection criteria in terms of polish, symmetry, proportions, and inclusions… Of course, their inventory of Canadian Diamonds is updated all the time, so feel free to contact me if you would like me to help you find a Canadian Diamond from Blue Nile.
