What is a Square Halo Diamond Ring?

A square halo ring compared to a commonly found round halo ring.

The halo ring is a setting where the center stone is surrounded by a collection of melee (small) diamonds. This “halo” of smaller diamonds is literally how the design style got its name and a square halo simply means that the halo is made in the angular shape of a square.

A well crafted square halo ring can add a dimension of sparkle to the ring and enhance the perceived size of the center diamond. Besides giving a better bang for your buck, the halo setting also acts as a protective buffer for the center stone to prevent accidental damage.

Now, I know some people may think that a square halo diamond ring would require a square-cut center diamond like a princess or Asscher cut. However, this is a misconception. The choice of center stone can vary depending on your own personal preferences.

Whether it is a round cut or a cushion-cut center diamond, there are ring designs that feature a square halo for these diamond shapes.

Over the years, there had been a steady increase in the demand for square halo engagement rings and a variety of designs created for different diamond shapes. There are also a lot of stylistic variations in the market – for example, rounded halo corners to soften the ring’s appearance as opposed to sharp ones and double or even triple halo designs for the ultimate wow factor.

At the end of the day, choosing the exact style of square halo rings would depend on your own personal preferences and lifestyles.

3 Important Things to Bear in Mind When Buying a Square Halo Ring

First of all, you will need to pay attention to the matching of the center stone and the square halo ring setting. Depending on where you buy the setting from, the specifications and melee quality used would differ.

This information (e.g. G/H and VS clarity diamond melee quality) can usually be found on the listing page or will be provided by the jeweler. In order to create a consistent appearance, the specifications of the center stone should be matched to the quality of the melees within 1-2 grade differences.

As you can see in the comparison above, the K color diamond shows a slightly more pronounced yellowish tint that makes it stand out from the setting’s color. If you want a blended appearance, I would recommend a center diamond with color rating between F to I. On the other hand, if you like the yellowish contrast, then it is perfectly fine to go with the K. You will also get to save some money too!

When it comes to clarity, there is more leeway as differences in clarity aren’t that noticeable to the naked eye. As long as you pick an eyeclean diamond, you could go down to SI1 clarity or even as high as internally flawless if you like.

Secondly, craftsmanship standards are very important when it comes to buying a beautiful and long lasting piece of jewelry. Now, the million dollar question is how do you determine whether a setting is well made or not? Well, there are no easy answers here as it boils down to the experience of the jeweler.

Personally, I have vetted hundreds of jewelers across the world and I can tell you that it’s hard to find someone that can consistently make great settings. In general, I look out for details like how well matched the melees are, how consistent the square halo is constructed, shank symmetry, prong placements, finishing and etc.

If you want to see indepth pictures and videos on assessing craftsmanship quality, check out the reviews of the rings I previously bought with these links here and here.

The third most important thing to bear in mind is to make sure that the center stone is selected for cut quality and light performance. Round cut diamonds are relatively easier to select because of their more established cut grading system compared to fancy shape diamonds.

One of the biggest mistakes I see beginners make is to solely rely on what is stated on the grading report and take the cut rating as the gospel. The fact is that there’s plenty of mediocre diamonds within the GIA triple excellent of AGS triple ideal ranges. In order to find a truly well cut diamond with the best sparkle, you will need to rely on tangible data like idealscope or ASET images to help you determine performance.

I’ve laid out a step by step guide to help you navigate this selection process. And if you are in the market for a fancy shape diamond like a princess cut or an Asscher cut, simply head over to the respective sections of Beyond4cs.com to find out how to choose them.

Summary: An Overview And Time to Go Shopping!

I hope this article has offered useful insights into buying a square halo diamond engagement ring. Personally, I love halo rings that also have pave shanks as they inject a lot of sparkle and life into the ring’s overall appearance.

Square halo engagement ring settings can make a bold statement and are very cost-efficient when it comes to enhancing the bling factor. This is because the halo helps the center stone look bigger without you having to pay the premium for a larger carat size diamond.

Before we wrap things up, I want to leave you with some information on the best places to buy square halo diamond rings. These are retailers that offer GIA/AGS certified diamonds and extensive collections of ring designs.

White Flash – A vendor that specializes in high performance super ideal cut diamonds. On top of magnified diamond photography, White Flash offers tangible data like the ASET and Idealscope images to show how well cut their diamonds are. They also have a wide range of beautiful in-house ring and designer settings to cater to different tastes.

James Allen – They offer incredibly detailed videography of their diamond listing and settings. This makes it really easy for beginners to see exactly what they are getting and perform a proper assessment of the diamonds they are buying. Besides GIA/AGS certified diamonds, James Allen also has a big inventory of lab created diamonds for people who don’t want to buy natural stones.

Blue Nile – They are the world’s largest online retailer of diamonds and you will be able to find something that fits any budget and style here. Blue Nile also offers video listings of their diamonds and work exclusively with some designers on their platform.

All 3 vendors are reliable places where I’ve personally bought multiple rings from. If you want to shop completely risk-free for a high quality ring at a competitive price point, make sure you check them out! Good luck with your search!

    I found your blog online and just wanted to say thanks for sharing your wealth of knowledge and willingness to help people on their challenging and often confusing diamond journey. I find your practical and no bs approach to informing the general public very refreshing!

    I’ve been doing research for the past several months on finding the best possible princess cut diamond within my budget. This will be for an engagement ring for my girlfriend. I’ve narrowed down my choices to several selections from white flash “a cut above” and would really appreciate your feedback in selecting the best pick from the bunch.

    I apologize in advance for the long email, but I would just like to provide you with as much pertinent info as possible.

    My girlfriend wants a princess cut and has a preference for size and color, with size probably winning out as long as the color still appears colorless. Inclusions are not so important as long as it is eye clean. I believe cut should not be sacrificed, hence my choice to stick with the ACA line from whiteflash. I want to find a colorless looking diamond at least 1.5carats that is as sparkly as possible. My budget for the diamond alone is around the $12k range. I’m practical though so if I can stay under budget, all the better, haha. I also know she would like a cushion shaped halo setting and for the center stone color not to stand out from the setting stone color.

    Here are the ring options:

    https://www.whiteflash.com/loose-diamonds/princess-cut-loose-diamond-4087225.htm

    https://www.whiteflash.com/loose-diamonds/princess-cut-loose-diamond-4087222.htm

    https://www.whiteflash.com/loose-diamonds/princess-cut-loose-diamond-4007489.htm

    I plan to put the diamond into this platinum halo setting:

    https://www.whiteflash.com/engagement-rings/diamond-settings/amphora-for-princess-diamond-engagement-ring-1520.htm

    I’m tempted to opt for the 1.7carat diamond, but I am not sure if I should be concerned with the H color, especially in relation to the F/G color stones in the setting. Will it stand out too much? Also, I’m not sure how favorable the ASET image is for the 1.7c diamond. The other diamonds seem to have more bright red on their ASETs. But the 1.7c diamond also has the most favorable inclusions in my opinion.

    Two of the other diamonds have better color and all have possibly better ASETs, but they are also a smaller carat wt and although they are labeled “eye clean”, I’m not sure if I should believe it blindly. I can easily spot a black dot inclusion located left of center on the F colored diamond, as well as other ones across the table surface.

    We are Asian, like you, and I happen to like the thought of an icy white sparkly diamond. I feel like size matters more to my girlfriend though, although she definitely does not want a colored diamond.

    If it helps, I am not stuck on buying from whiteflash only and am open to other stores. I’ve just heard great things about their ACA diamonds and thought it would be a safe bet.

    Sorry for the long-winded message. This is the biggest purchase I have ever made and I highly value your opinion on the matter.

    Thank you so much in advance for your consideration and I hope you can please take the time to offer your input!

    WF is one of the best vendors to buy a super ideal cut princess diamond.

    For such a large size diamond and for a non-round stone, I would recommend at least a H if you are color adverse. Watch this video and see if you are OK with an H.

    Now, I reviewed the diamonds and can tell you that all 4 have superb performance. For best overall value + performance, have an extremely strong preference for this diamond:
    https://www.whiteflash.com/loose-diamonds/princess-cut-loose-diamond-4087222.htm

    This would be my second choice:
    https://www.whiteflash.com/loose-diamonds/princess-cut-loose-diamond-4007489.htm

    Go for either of these. If you value carat size more, then go for the 2nd diamond.

    By the way, this setting you chose is a great looking design and I love the design elements it has.

    With a halo setting, I would say that you can get away with a Large looking ring with the first diamond. It’s a question of how big you want the ring to look now. Let that help you decide which to get.

    Thank you so much!

    My girlfriend really values size and would most likely be okay with an H. So I am leaning more towards your second choice.

    Do you think the F/G color stones in the settings will clash with the H center diamond?

    Nope. It would not be an issue. The side diamonds are too small and if their color varies a few grades from the center stone, it’s perfectly fine. So no worries there, go with the H diamond if that fits your needs. Both are superb options.

    If I may seek your assistance one more time, which would be your pick between these 3 diamonds? Priorities are size and color. They are all considered eye clean, but I worry about the location of the inclusions on the higher color grade diamonds.

    I realize the first two are higher color grades and will cost more because of that, but do you think it is worth it in your opinion? Or would it just be throwing more money into a negligible visual difference?

    Thanks again for your help

    The 3 diamonds are all eyeclean and color is subjective.

    If you are color sensitive, then get this diamond: https://www.whiteflash.com/loose-diamonds/princess-cut-loose-diamond-3891971.htm?a_aid=recommended it’s a better diamond over the F color option and is larger.

    It really depends on what your preferences are at this point.

    https://www.whiteflash.com/loose-diamonds/princess-cut-loose-diamond-4007489.htm?a_aid=recommended is perfectly fine as well. So, make the choice between these 2.

    I’ve read that there are generally 2 categories of square halo diamond rings and they can be classified as designs that have a round center diamond or a squareish center diamond (e.g. princess or Asscher cut). But what are the differences between them and is there anything I should look out for when buying a non-round center stone.

    There are a number of differences between choosing a round cut diamond for a square halo ring compared to choosing other fancy shapes. First of all, round cut diamonds are relatively easier to purchase because of the availability as well as the selection process. It is easier to choose a well cut diamond because of the established science in light performance and data available in grading reports.

    For example, the GIA report contains a cut rating while the AGS report provides light performance data. This makes it easier to assess diamonds for their sparkle factor. Round cut diamonds tend to display broader flashes of lights instead of splintery looks.

    On the other hand, fancy shape diamonds like princess cuts are much cheaper per carat. If you were to buy a 1 carat princess diamond, it would cost 30-40% less than a round cut diamond. Likewise, this applies to many other diamond shapes. The key problem with most fancy shape stones is that they aren’t well cut for light return and a layman would have difficulty choosing one unless you understand what you are doing.
