Top 4 Places to Buy Marquise Cut Diamonds
#1 Buying Marquise Diamonds at James Allen
James Allen doesnโt have the largest selection of marquise diamonds on our list, but thereโs other reasons why theyโre deserving of the number one spot. They carry over 1300 loose marquise diamonds of various grades and qualities.
If youโve read any of our other guides, youโll probably notice James Allen frequenting the top of our list. One of the big advantages they have on the other guys is that they have full 360ห view on all of their marquise shape diamonds. All of their marquise diamonds in their inventory have GIA, AGS, or IGI certifications. Iโd advise staying away from IGI certifications for natural diamonds though.

The unique and slender shape of a marquise diamond cut stone limits the types of ring setting available for this shape. James Allen has around 150 settings for you to choose from.
Every engagement ring should have a maintenance plan and a manufacturerโs warranty wonโt cover it. James Allen gives all their customers a free lifetime warranty that covers prong retipping, rhodium plating white gold, and other wear and tear issues engagement rings face over the years.
#2 Buying a Marquise Diamond at Blue Nile
On the other hand, Blue Nile has the biggest selection of marquise diamonds on our list today. With over 4,000 different marquise diamonds of varying qualities and sizes, thereโs plenty of choices. Unfortunately, not all of the diamonds at Blue Nile have interactive 360 video like James Allen. When we filter that though, weโre reduced to around 1,900.
Still, thatโs a generous amount.
Blue Nile often competes with James Allen when it comes to price. However, when it comes to customer service, Blue Nile has the edge. They were the first online diamond retailer and have built up an excellent reputation with their customers. They are a trusted name in diamonds online.
If you buy your marquise with Blue Nile, youโll also get a free jewelry appraisal, alongside your GIA or AGS grading report. Unlike James Allen, Blue Nile only offers grading reports from the best authorities for natural diamonds.
What they donโt give you is a free lifetime warranty to cover the ring setting of your marquise engagement ring. You can get free cleaning and inspections of your prongs, but repair work is done at a cost.
#3 Buying Marquise Shaped Diamonds at Ritani
Ritani has a pretty large selection of marquise diamonds for excellent prices. With their diamond market analysis, they have transparent pricing. They show you the cost breakdown of your diamond, including what it costs from the diamond manufacturer.
Not all of Ritaniโs 1,900 marquise diamonds have 360ห video. Unlike Blue Nile, you canโt filter which ones do. That means itโll take more time to find your perfect diamond. The ones that do have 360 view are uncontrollable. Theyโre video clips rather interactive video.
I do like that you can view the diamond certificate for your marquise diamond right there on the page. Some of our other retailers donโt do that.
Ritaniโs a ring designer, so the settings for their engagement rings may be more expensive than the average retailer. The diamonds themselves are affordable, but the settings are more costly. However, Ritaniโs exclusive ring settings canโt be found in other places.

Ritani has a lifetime warranty that will cover everything you need to keep your engagement ring looking pristine and your marquise diamond protected for years to come. Itโs also free, but must be registered online.
#4 Buying a Marquise Shape Diamond at Clean Origin
Clean Origin has the smallest collection of marquise diamonds but still has over 500 loose marquise diamonds to choose from. You wonโt be able to be too picky with your grades though. If youโre looking for a smaller carat size, Clean Origin might not be the best choice.
You see, all the diamonds at Clean Origin are lab-created diamonds. They are real diamonds that have formed in a lab instead of the earth. Lab diamonds have the same properties as natural diamonds but are less expensive.
Lab Created Marquise Prices from Clean Origin
Some of our other diamond retailers like Ritani and James Allen also offer lab created center diamonds. But Clean Origin is the only one that has ring settings with lab created accent diamonds. All of their gold and platinum is recycled. If buying ethical diamond engagement rings are a must on your list, Clean Origin would be an excellent option.
As for warranties, the Forever Service plan is a great option to add to your purchase. Their warranty covers all the routine repairs youโll need for your engagement ring. The only downside is that itโs a paid warranty, not free. Still, itโs worth it. Plus itโs based on the overall cost of your diamond.
What to Look for When Buying Marquise Cut Diamonds
Cut Quality and Grades
Like majority of fancy shapes, the marquise cut diamond doesnโt have an official cut grade, though they may be sorted that way online. When choosing the cut quality of a marquise diamond, you need to pay attention to its shape appeal, not just the numbers and measurements.
The recommendations for a marquise cut diamond with excellent cut quality are as follows:
Length to Width Ratio
The length to width ratios of diamonds can be abbreviated as L/W ratio under diamond details. The ideal length to width ratio of a diamond varies among shapes. For a marquise diamond, it can determine how skinny or wide the heart looks.
Length to width ratio (L/W ratio) to look for:Between 1.85-2.0
The length to width ratio of your marquise diamond will determine the overall shape appeal. Though most online views have a magnified view of their diamond, thereโs also some that have a minimize feature. This can really help you see if you have a well-cut marquise diamond on your hands.
Marquise diamonds with length to width ratios of 1.85 may appear shorter, while 2.0 will make it appear longer. Some retailers will even let you filter them by their length to width ratio.
Girdle
A girdle is the outermost edge all the way around a diamond. Most diamond girdles are thin to slightly thick.
What to Look for in a Girdle: Thin, slightly thick
Itโs better to choose a marquise diamond that is slightly thick at the ends. Thin is okay too, but stay away from extremely thin girdles. The girdle thickness can impact the pointed ends of marquise engagement rings.
Other Recommendations:
Desirable Table Size: 53-63%
Desirable Depth: 58-62%
Clarity Grades
Marquise diamonds are brilliant cut, so they have extra facets that can hide diamond inclusions. There are many types of inclusions, but too many of them can affect your diamondโs appearance. Some are more prominent than others and some have a larger number of inclusions. Your diamondโs clarity grades determines whether you have an eye-clean diamond or not.
SI2 Marquise Diamond Clarity
VS2 Marquise Diamond Clarity
A marquise diamond doesnโt need a super high clarity grade, unless you really want it. If it was a step cut diamond shape, like an emerald cut diamond, itโd be another story.

The bottom line is, itโs not hard to find eye-clean marquise diamonds without obvious imperfections on the SI clarity tier. But if youโd like to go higher to VS2 clarity, thereโs nothing wrong with that either.
Color Grades
Evaluating color of a marquise diamond is up to personal preference. Some people are more sensitive to brown or yellow tint in a diamond, while others not so much. Some people notice the tint and prefer the diamondโs color for their skin tone.
The color grade you choose for your marquise diamond doesnโt impact its brilliance or durability. It is completely up to you. Of course, marquise diamonds of high color grades such as DEF will be considered more valuable-and more expensive.
K Color Marquise Diamond
I Color Marquise Diamond
F Color Marquise Diamond
If you want a recommendation, Iโd stay above an I color grade for a marquise diamond. Iโm very sensitive to color and a marquise diamond can reveal color tint more than with some of the other diamond shapes. I suspect it has much to do with the elongated shape of the marquise diamond.
Carat Weight
While the elongated shape of a marquise diamond isnโt a huge advantage toward a cheaper color grade, it works in your favor regarding carat weight. Fancy shapes that have elongated edges look bigger than other diamonds.
For example, a hereโs a 2 carat marquise diamond cut next to a 2 carat round diamond. The cutting styles for each shape is different. Marquise diamonds are cut more shallow with longer face-up carat size. Round cut diamonds have a deeper pavilion and a smaller face-up size. They may be the same carat weight, but the perception of size is different.
Keep in mind that this only works if youโve purchased marquise diamonds with ideal length to width ratios.

Red Flags When Buying A Marquise Shaped Diamond
Every shape has itโs pros and cons. The marquise cut diamond engagement ring is no exception. Here are some things to keep in mind before you buy marquise engagement rings.
Engagement Ring Settings
Marquise diamonds have pointed ends, which means theyโre extra vulnerable to chipping. But donโt worry, this can be a problem with many diamond shapes. As long as the marquiseโs pointed ends are covered by either prongs or metal that protects the edges.
Round prongs and claw prongs can protect the edges of a marquise diamond engagement ring, but V prongs are the best protection. Instead of just the pointed ends being covered, the whole corner is secure.

However, you should know that all prongs are suitable for a marquise diamond, but you can always take extra precaution if youโre worried.
The Bow Tie Effect
A bow tie is an optical effect that appears on certain fancy shaped diamonds. Marquise cut diamonds, oval cuts, and heart cut diamond shapes can show the bow tie effect.
Bow ties show on nearly all these shapes. Theyโre not necessarily a bad thing either. The bow tie effect is purely optical and has no contribution to the durability of your diamond. Some people feel a bow tie gives their diamond some extra character.
Prominent Bow Tie
Medium Bow Tie
No Bow Tie
You be the judge yourself.
A bow tie happens on a marquise cut diamond during the cutting process. It happens to shapes that have brilliant cutting techniques. Brilliant cut diamonds have extra facets. When the facets arenโt cut optimally, the light reflection casts a shadow shaped like a bow tie. A more prominent bow tie will usually cost less.
Deciding whether the bow tie effect adds or takes away from your shape appeal is up to you. You canโt sort marquise cut diamonds based on their bow tie. Thatโs why shopping online from a wide selection of marquise diamonds will give you more options. Youโll have a much harder time spotting a bow tie in-store, even under a microscope. 360ห views online make them much easier to see.

- Make sure your engagement ring setting covers the pointed ends of your diamondโs girdle. V-shaped prongs can offer extra protection for a diamondโs girdle.

- Choose a marquise diamond with a girdle thickness of thin to slightly thick.
- Keep your length to width ratio between 1.85-2.0 for ideal marquise diamond engagement rings.
- Select a loose marquise diamond online instead of in-store for a bigger pool of diamonds to choose from
- Choose an online retailer that offers 360ห view on their marquise cuts to see the bow tie effect clearer
- Choose an online retailer that offers a warranty, whether paid or free.
