Let's get into it!

2. Blue Nile (top selection)
3. Whiteflash (best diamond cuts)
4. Brian Gavin
5. Abe Mor
6. Leibish and Co

Buying Diamonds At James Allen

James Allen is the best diamond retailer when it comes to buying diamonds online. They're investing millions of dollars in optimizing and fine tuning the online buying process for jewelry.

One could argue they're on the cutting edge of what's possible in e-commerce.

They do have a couple of physical stores in Georgia and New York, but mostly operate online. People love buying diamonds and engagement rings with James Allen because of their reputable name among online retailers in jewelry.

They offer a complete 360 degree view of the diamond, allowing you to see any diamond characteristics in that piece. The picture is extremely clear and allows you to see the slightest of inclusions without actually being physically present.

You can even set your loose stone in a pendant, earrings, or ring setting, allowing for a complete customization of your piece. 

While many of these features can be seen at other diamond retailers, James Allen has the best benefits for your diamonds online.

They offer their customers a lifetime warranty that includes retipping of prongs, deep cleaning, polishing, and rhodium plating.

All other repair work is sent in for an estimate, and then done if you decide to go ahead with the price.

From what I can tell, they do not cover loss of any stones, so keep that in mind when considering this retailer. James Allen also gives you hassle-free returns for 30 days.

While many retailers make you pay a shipping fee for returns, James Allen does not.

They'll send you a pre-paid label and refund back to the original card of purchase.

They really are the best package when it comes to getting the most out of your purchase. 

Your ring is eligible for a Lifetime Upgrade for trading up at least 2x its original value. That's basically like getting a brand new ring for half of what most people would be paying! Lastly, James Allen also offers you free resizing for a year.

Pros

  • Lifetime warranty
  • Free sizing for a year
  • Lifetime upgrade
  • Clear 360 view
  • Cons

    • Not many choices in diamond fine jewelry 
    • Does not cover loss of stones in settings

    Buying Diamonds At Blue Nile

    Right behind James Allen, is Blue Nile in terms of online buying experience for diamonds and gemstones.

    They have a similar 360 degree  camera for  select pieces,  but most are generic  2D pictures  with  some shots of models wearing the jewelry.

    When you buy diamonds from Blue Nile, you can be sure you are getting them from reputable diamond dealer.

    Blue Nile offers the best selection of everything from loose diamonds to tungsten carbide rings for men. They also have a wide range of diamond fine jewelry, unlike some of the other competitors that focus solely on loose diamonds. 

    As for warranties, I have to say I'm not a huge fan of Blue Nile's. The jeweler has the typical manufacturer defect policy, but other than that, everything is out of pocket.

    They recommend you get your jewelry cleaned and inspected for retipping of prongs or loose stones ever six months. They'll inspect it for free but you will have to pay if it needs any work.

    In addition to the inspection, you also have to pay to ship it to be inspected. And, if you choose to have your diamonds worked on by anyone else, it voids the warranty.

    Blue Nile has it all when it comes to diamond certification. You may receive a GIA grading report from the Gemological Institute of America, Gemex Light Performance report, and a GIA Diamond Dossier for all diamonds under 1 carat weight. 

    When inspecting the diamond characteristics with Blue Nile, I love that they are like James Allen with the way you're able to rotate the diamond, rather than the view. I really wish they had HD viewer though, because I can't really see it as sharp as I'd like to.

    Pros

    • Diamonds from reputable dealer
    • Loose diamond and diamond fine jewelry
    • Diamond certification
    • Rotating view of diamond on website

    Cons

    • Unimpressive warranty
    • Diamond view on website is not as high definition as James Allen




    Buying Diamonds At White Flash

    White Flash is an online diamond jewelry retailer that also has a brick and mortar store in Houston, Texas.

    When it comes to buying diamonds at this store, they make it pretty easy on their website although they have some big differences when compared to James Allen or Blue Nile.

    whiteflash online diamond jewelry store

    I looked at their loose diamond collection and I do like the way they have their filters set up. 

    I really like that when I search for a certain loose diamond, I can scroll over each result quickly and narrow it down to ones I'm interested without ever having to open a tab. Very convenient.

    While White Flash has plenty of diamond ring and jewelry options, they are definitely lax when it comes to gemstone jewelry. In fact, they don't have any on their site, but you can inquire within and they can arrange an order for you. 

    whiteflash diamond retailer

    White Flash prides themselves on their own American Gem Society (AGS) certified diamonds. They are also laser-inscribed with a unique number so you will always be able to identify or report it if stolen.

    Not only do you get the 4Cs of your diamond certified, but each diamond in their Premium and Expert selections also comes with a full light performance analysis for brilliance, fire, and dispersion.

    This jeweler also offers 100% trade up for life, 30 day return policy, and a buyback program after one year. 

    Some of the staff are also GIA certified through the Gemological Institute of America, the most prestigious university in Gemology. You can be assured you are getting correct information from White Flash.

    Pros

    • Laser inscribed
    • Money back guarantee
    • Name brand selections
    • 30 day returns
    • Buyback

    Cons

    • Bad diamond lighting for viewing characteristics
    • No gemstone jewelry (or loose stones) 



    Buying Diamonds At Brian Gavin

    Aside from James Allen, Blue Nile, and Whiteflash, Brian Gavin is another popular online jewelry store with some major differences.

    brian gavin inline diamond retailer

    Brian Gavin is an online retailer that offers stunning loose diamonds of various shapes, cuts, carat weights. They even have their own hearts and arrows patterned diamonds and loose gemstones as well.

    Their gemstone collection isn't the greatest. They only offer rubies, emeralds, and sapphires.

    Also, looking at the prices, I can say I've seen much cheaper and bigger selections elsewhere. They are really beautiful stones, but I can't imagine many people buying gemstones from this jeweler.

    I do like that they have a decent selection of colored diamonds.

    Brian Gavin offers you a nice discount for purchasing via bank transfer rather than using a debit or credit card, which is kind of nice is you don't mind that. They only offer lifetime upgrades on their hearts and arrows diamonds and their "blue" diamond collection.

    Any other diamond jewelry is not covered under that. However, unlike other diamond retailers, you can return an engraved ring as long as it is on the inside of the shank of the ring.

    Most places won't let you return any type of engraving. Just make sure to do it within their 15 day refund policy.

    I don't really care for their view of the loose stones. Brian Gavin gives you a view of your loose diamond, but you are simply moving the camera around the diamond, not the diamond itself.

    You can't control the light to look for inclusions and it's certainly not HD. Their diamond selection is also a little small and pricey compared to some of the other retailers. 

    Pros

    • Sell diamonds for cash
    • Carries more shapes
    • Fancy yellow category

    Cons

    • Have to sign in to see prices
    • Not a wide selection of jewelry
    • No info on warranties

    Buying Diamonds At Abe Mor

    https://www.abemor.com/

    Shopping at Abe Mor for diamonds may takes some getting used to, but you'll have the hang of it in no time.

    The website is different from most of the online diamond retailers in our list. It can make diamond buying just a little confusing. Abe Mor Diamond Cutters is a jewelry store that looks like its meant for diamond vendors, rather than normal customers. 

    Still, you can purchase from them. They carry loose stones as well as diamond fine jewelry, but they don't have a very wide selection.

    Read Also: What are the types of diamond cuts?

    Looking at the site, I think the main appeal to Abe Mor is that it allows you to sell your own diamonds. They will determine how much your diamond is worth and as long as its over .3 cts, they are worth something. 

    Abe More prides itself on being the one that gives you back the most money when you sell through them. Each offer is individualized through a query, rather than being one ballpark price.

    They send you everything you need to ship it to them and appraisers will inspect it, then give you a final offer. Once you accept the offer, you will receive payment within one business day.

    They also respond to your initial request within one business day. The process is very quick and clean. 

    Most diamond retailers, if not almost all, don't allow you to sell your own merchandise for cash. Generally, they'll allow you to use it as a trade-in and the deal is pretty dismal in retrospect.

    This factor alone makes Abe Mor worth checking out, especially if you have old diamonds laying around. 

    In their loose stone sections, you can buy diamonds in more fancy shapes than the other stores on this list.

    Most stores carry around 10 shapes in their loose stones area, but Abe Mor does 12.

    The other two cuts are a couple of the most early diamond cuts known, the old mine cut and old European cut.

    Additionally, they have a section for matching diamond pairs for earrings and a fancy yellow diamond section. 

    Pros

    • Sell diamonds for cash
    • Carries more shapes
    • Fancy yellow category

    Cons

    • Have to sign in to see prices
    • Not a wide selection of jewelry
    • No info on warranties



    Buying Diamonds At Leibish & Co.

    https://www.leibish.com/

    Leibish and Co. is the diamond dealer you want to visit when you're looking for a diamond outside the box. They specialize in fancy diamonds, or colored diamonds.

    They offer a wide range of results for every color diamond, including the most rare colored diamond, the red diamond. Granted, the price is off the wall for a high quality one. 

    The prices at Leibish and Co are high when it comes to the average diamond buyer, but its is wholly dependent on the color of diamond and how vivid it is.

    Colored diamonds have 9 grades when it comes to color, which is where they increase in price. Not only do they sell the colored diamonds, they also have colorless diamonds, much to most people's surprise. 

    Read Also: What's the deal with diamond colors?

    They also have this cool section on their site called The Vault. It features some of their most prized stones in the store and requires a written inquiry about each if you're purchasing.

    I can only imagine how much they cost. Leibish and Co also allows you to look at the stone at one of their affiliate retailers, should you want to see it in-person rather than just purchasing off the web. I thought that was unique. 

    And if that isn't enough, they still offer a 30 day money back guarantee or refund if need be. They offer a lifetime warranty for all of their items, but it will only cover free wear and tear repairs like prongs, rhodium plating, or polishing.

    You also get one free ring resizing if you need it and it can only be within 1.5 sizes of the purchased size.

    When you send in your merch to be repaired under warranty, you are responsible for paying the shipping and insuring the ring.

    When they send it back to you, Leibish and Co. insures and ships it back to you on their end.

    All other repairs can be sent as well, but at a cost. Lastly, the free resizing can be done at one of their affiliate jewelry stores near you. 

    Pros

    • High quality colored diamonds
    • Unique designs
    • Free lifetime warranty covers normal wear
    • One free resizing


    Cons

    • High prices
    • Few colorless diamonds
    • Can only be resized 1.5 sizes


    Online Diamonds FAQ: What To Know?

    Is It Cheaper To Buy Diamonds Online?

    It's a hard question, it really is.

    There are so many different diamond retailers both online and at physical stores. Some places are going to sell diamonds at a higher cost if they are brand name, have special cutting techniques, or even name brands like Verragio or Ritani.

    There are a lot of factors that will make diamonds cheaper or more expensive. 

    The main factor in pricing a diamond is their grades within the 4Cs: carat, cut, clarity, and color. Some diamond shapes are more expensive as well.

    The round brilliant diamond is actually the most expensive of all the cuts. But the Asscher cut diamond is going to cost less. 

    best online diamond stores

    Similarly, a high quality cut diamond such as an ideal cut is also going to be on the higher end of diamond prices. 

    So is it cheaper to buy online? My answer is not necessarily, but I can guarantee you can find a cheaper and better quality diamond than you'll find in a diamond retail store.

    Corporate jewelers get away with charging you more for a lower grade diamond than an online retailer might. 

    This is because these jewelers are banking on the thought that you would rather purchase something you can see rather than something you'd order online. 

    Red Flags When Buying Diamonds Online?

    While none of these online diamond vendors on this list are red flag worthy, there are a few things to keep in mind when buying diamonds on the net. 

    Blood diamonds are taken extremely seriously by diamond retailers. All of the retailers on this list are conflict-free diamonds, meaning that people are not being hurt as a result of the production of the diamonds.

    They are sourced ethically. Always look for sites that mention if they are conflict-free diamonds.

    Secondly, if you're thinking about buying diamonds from a place, make sure they are using proper terminology when referring to the quality. For instance, make sure they are being graded by the GIA 4Cs, and not their own system. Some places will also claim to be certified, but are only certified through their store. 

    Tip: Certifications by GIA, IGI, IGS, and GemEx are all legitimate certification authorities. Some stores may also do their own certifications in addition to one or more of those mentioned. 

    Lastly, make sure that your purchase comes with a solid return policy, just in case your diamond doesn't look like what you buy online. You may have to pay a shipping fee, but most reputable diamond stores will pay for it. 

    How To Get The Best Deal When Buying Diamonds Online?

    Generally the best deals (10-25% off) come during the popular holidays like Valentines Day, Christmas, Black Friday, etc.

    That said, I would advise you wait to buy anything until sales come online around these holidays. Lab created diamonds also offer a way of getting a bigger diamond with a better cut at a lower price that is essentially identical to the natural counterpart.

    Aside from just waiting for sales or buying a lab diamond, it pays to brush up on your knowledge of carat, cut, color, and clarity so you know what details to look for vs ignore.

    Thankfully, you can learn everything there is to know about diamonds through our buying guides and informational articles. If you are new to the diamond game and are considering purchasing, definitely brush up on your knowledge of the 4Cs.

    You'll learn that you don't necessarily need the top grades or biggest carat weights to get the best deal. 

    And of course, after you've learned the tricks of the trade, you can now utilize any deals the site you're buying off of may be offering. Double the discounts!
