Even though you may not have heard of this diamond store, they're no stranger to the business with more than 20 years in operation. Both accredited and "A+" rated by the Better Business Bureau, you can rest assured that your purchase is in good hands here. You can also see James Allen's commitment to their customers with 24/7 customer service, free shipping on all orders and on returns within 30 days, and a lifetime warranty (with certain terms and restrictions, of course).

Shopping for diamonds doesn't get any easier than buying from this store. First, decide whether you want an earth- or lab-created diamond (keeping in mind that synthetic stones are usually less expensive but offer identical visual quality and chemical properties seen in natural diamonds). Then, indicate any preferences for shape, cut quality, color, carat, clarity and price (or select "advanced options" if you are something of an expert and want to specify even further details like certification lab or fluorescence).

Once you've found a diamond you like, you'll have an abundance of information about the stone, from its certification to a representation of how large it will actually look on someone's hand.

One novel feature offered by James Allen is their Real-Time Diamond Inspection. Via screen sharing, you and one of their non-commissioned certified gemologists can review your favorite stones from the online inventory in 360° HD and up to 40x magnification; they will go over all of the stone's specifications, the grading certificate, and any points of interest. It's like having your own personal diamond specialist on call!

You can also see when you can expect your diamond to arrive: usually within 3-5 business days when just buying it as a loose stone; delivery times vary when mounted into a setting. When you select a diamond, you will have three options: add a setting, add a pendant, or add to cart.

We were pleased by the wide range of settings available for all diamond shapes. There were more than 600 options in James Allen's inventory, and even for an unusual asscher shape we had nearly 100 choices. There were the usual pave and solitaire styles, but also some more one-of-a-kind designs; some of our favorites were Twisted Vine, Vintage Round Diamond and Marquise Sapphire, and Art Deco Inspired Fleur-De-Lis. Although most of the images show the settings in white gold, you'll see other options once you select the one you like (e.g. yellow gold, rose gold, platinum).

Once you've chosen the stone and its setting, you'll see the guaranteed delivery time. Don't be surprised if you're given a date a month in advance; it takes time to get your stone in the hands of their jewelers to be placed in the setting. Chances are good that it will be well worth the wait: browse the reviews below the settings to see what other customers say about the ring (and see many photos too). In general, most customers give James Allen a 4- or 5-star rating, with plenty of compliments about the quality and value of the diamonds and settings, ease of working with customer reps, and on-time delivery.

By the way, when we visited the James Allen site, we spotted an offer for a $100 discount on our first order if we gave them our email address. However, the fine print specified that loose diamonds were excluded.

James Allen provides everything you could want from the diamond shopping experience: in-depth information about your stone, ample choices for settings, expert consultations and a wide array of customer-friendly perks and policies. It's easy to see why this diamond store earns our highest rating, and we highly recommend you begin your search here.

Where Can You Find the Best Selection of Loose Diamonds?

If you've ever gone to your local jeweler in search of one of these precious gemstones but left disappointed, you're not alone! Most brick-and-mortar jewelry stores can't afford to keep thousands of diamonds in inventory - both financially and logistically, it's just too risky.

With that in mind, it's easy to understand why so many shoppers are turning to online diamond stores. Why limit the possibilities to just a handful of stones in limited sizes and cuts when you can browse literally hundreds of thousands of diamonds across the spectrum of carat size, shape, clarity, and, of course, cost? The best online retailers make it easy to see a 360° view of each stone, plus any available certifications and ratings from industry-recognized appraisers.

Diamond Store FAQ

One of the most sought-after gemstones in the world, diamonds are one of the hardest substances known to man. Diamonds form from carbon under high pressure and temperature.
Fun backstory: diamonds weren't commonly used in engagement rings until 1947, when the British mining company De Beers featured them in an advertising campaign! The rest, as they say, is history. Diamonds now represent financial success, long-term commitment, and status.
Cut, carat, color, clarity. Cut is the only human "influence" on a gemstone: round, princess, cushion, marquise and oval are some of the more common shapes given to diamonds. Carat represents the weight of the diamond, with 1 carat equal to 200 milligrams. Color evaluates the stone using letters of the alphabet; the closer to "A" , the whiter the stone, though most people find stones in the G-H rating to still be icy-white in appearance. Clarity is a little more difficult for the average consumer to see, especially without magnification: the categories measure inclusions, or irregularities that happen during the formation of the diamonds but are hard to see without magnification, as well as blemishes like scratches or chips.
The names say it all: natural diamonds come from the earth, while lab-created or synthetic diamonds come from scientists! But, other than their origins, these two types of diamonds are exactly the same chemically and optically: even expert gemologists have a hard time telling them apart without using a jeweler's loupe! And, as you might imagine, synthetic diamonds are usually much more affordable.
These acronyms all refer to gemological societies and institutes with diamond grading scales used throughout the industry: Gemological Institute of America, American Gemological Society, European Gemological Laboratory, and International Gemological Institute. Generally speaking, GIA and AGS are seen as the most accurate and scientific, so if you're buying a higher-priced stone you may want to ensure that it's been graded by one (or both!) of those two systems.
If you're looking for a one-of-a-kind piece, you're not going to find it by buying the first pretty ring or solitaires you see at your local jewelry store. Many customers want something with a story that can be handed down as an heirloom: the shape of the stone chosen to match her eyes, the setting selected to complement his personality, and so on. Buying loose diamonds is the first step in a truly unique piece of jewelry.
While you'll find no shortage of companies wanting to sell you diamonds as an investment, most experts say that the average consumer isn't likely to profit from them. Unless you're buying extremely large diamonds (e.g. 20 carats or more) or ones with a noteworthy history (like being owned by a celebrity), you may have a hard time selling the diamonds you buy for more than you paid. If you're planning on spending a significant amount of money for a diamond, do it because you appreciate the beauty or want to own (or give) something precious - but save your investments for more reliable means of generating profits!
Absolutely. Of course, you shouldn't buy a diamond from an online retailer without doing your research: choose a business with a well-established history, preferably with a high rating from the BBB, and be sure that the diamond you buy has been rated and certified by one of the independent institutes or laboratories mentioned above. You can rest assured that the diamond retailer will take every measure to get your stone delivered safely, including tracking and insurance.

Buying loose diamonds is a wonderful way to create a one-of-a-kind piece of jewelry: once you've chosen the stone, the sky's the limit with what you create next. The online diamond store you select will probably have an impressive array of settings: for engagement rings alone, the possibilities are nearly endless and range from traditional solitaires to the optical illusion of a tension set.

However, as you'd imagine, it's important to choose your retailer carefully. Your diamond purchase could represent an heirloom to cherish and pass down through the years, and you want to ensure that you get exactly what you pay for. We recommend keeping these criteria in mind, to help you choose the best diamond retailer:

  • Selection. How many loose diamonds does the store keep in inventory? Are there many choices in the cut and size you prefer? Will you be able to have your diamond placed in a setting you love?
  • Price. How do the prices compare with rival diamond sellers? Are there any promotions or perks like free shipping to make your purchase more affordable?
  • Certification. Does the retailer have documentation from GIA, AGS, IGI or EGL that certifies the qualities of your stone? Especially if you're buying a more expensive diamond, you want proof that the carat size, clarity and color are as-described.
  • Reputation. What do other customers say about their experience buying diamonds from the retailer? Has the Better Business Bureau rated the store or received any complaints? Buying a diamond is no casual purchase for most people, and so it's worth taking some time to make sure that the store has a history of honest, professional interactions with their customers.
