Not only one of the best known name in the world, but JamesAllen.com is actually one of the premiere diamond and diamond jewelry retailers you’ll find.

No wonder we chose them as our top pick as the best place to buy diamonds and jewelry online.

But why? What makes JamesAllen so special? Where they are the best and where they need some improvements?

This is what we will see in a full & thorough review of JamesAllen.

  • If you’re looking for a small diamond (<0.7 carat), your options might be limited if you’re looking for something specific

JamesAllen & Revolutionizing Diamonds Imaging

When we started this blog around 2014, JamesAllen wasn’t known as of it today, (personally I remember when I first heard of JamesAllen, I thought it was the known British philosophical writer), but when we visited their website, they had something no other company we’ve come across had.

Actual images of the diamonds they were selling, not stock photography or generic pics like we used to see in 2014.

What’s more is they offered 360-degree 3-dimensional views directly on their website. Needless to say this was very, very intriguing.

This gives immediate “relief” that the company was so confident in the products they sell, to the level they were ok with you scrutinizing them for hours behind your laptop screen.

We’ve all been to jewelry stores where the sales person makes you feel uncomfortable for examining what you intend to buy closely.

It’s as if you’re wasting their time (and.. let’s be honest… no annoying sales people pushing things down your throat is one of the best things about buying online).

JamesAllen Collection & Inventory

For decades, Blue Nile occupied the “largest diamond store” spot, whether online or among physical stores, this was the case for long time.

Later 2018 & probably 2019, JamesAllen heated up the game, they knew how to scale up their inventory while maintaining their best imaging standards (keep in mind, Blue Nile at that time had almost no images of diamonds, while James Allen had 360-degree with 20x magnification for EVERY single diamond).

When we’re talking about “large inventory”, we’re not talking about thousands or even tens of thousands, the competition between JA & BN was who will have half a million diamonds for immediate purchase on the website.

Insane number, isn’t it?

Indeed, we remember when we kept updating numbers for inventories of these stores when we revise content, JA has 200k, oh 1 second, BN made it to 240k, 6 months later >> check inventory, it’s 400k!

Today (Nov. 2022., James Allen has 575k loose diamonds (all shapes), and Blue Nile has 625k! 1.2 million diamonds in just 2 stores online, what a crazy world we live in!

Beside the standard cut grades (good, v.good, and idea), James Allen offers best of the best ideal cuts, their True Hearts™ line of diamonds, they guarantee that these diamonds have unmatched sparkle & brilliance, thanks to the perfect internal symmetry and proportions, and the highest gem grading for cut and polish.

True Hearts™ collection comes in round, princess, and cushion shapes.

JamesAllen Website Shopping Experience

Put simply, the way things are laid out and the control you have over what you want is second-to-none when you browse at JamesAllen.

If you work in website design, or at least have the passion for this, you will immediately tell that there were a lot of sleepless nights for those who created this journey, the listing, filtering, customizations, comparison, up until checkout, you get the feeling that you’re mastering using the site, from the first time you visit it.

You can start by choosing either the stone (they also sell other gemstones) or the setting you want.

If you want to browse loose diamonds, you can.

You want to explore rings only? That’s also available.

It’s pretty easy to navigate around, choose various options and examine your diamonds, gems and jewelry close-up. Filters & ordering options on diamonds page are very intuitive (they must be, when you’re selecting between 575k diamonds!).

You can go broad – like any type of princess cut diamond. Or you can narrow your search by shape, color, cut, clarity, price, carat and even more (under advance options).

And with each choice, you’re shown how many diamonds match your criteria and a 3D image of the actual product.

JamesAllen Lab-Created Diamonds

Can’t exactly remember when this started, but probably later 2019 or early 2020, JamesAllen decided to get into the lab-grown diamonds industry.

If you’ve already read our review for lab-created diamonds, you will relate how hard it might be for a big name like JamesAllen to get into this industry or keep doing what they’ve been doing for +15 years.

It’s because people are still very careful (and probably anxious) when they hear the term lab-created diamonds, we won’t go into this debate, it’s already covered in that post.

So, JamesAllen said yes, and started offering lab-created diamonds (at that time, graded by IGI only), and they started with kind of limited collection, less than 10 thousands as we remember (yes 10k is tiny compared to their earth-mined diamonds).

As of now (2022., JamesAllen has +62k lab-created diamonds, mostly graded by IGI, but recently they started offering GIA grading for their lab-created inventory.

The same details you expect on a natural diamond page are also available for lab-grown one, as well as very HD 360-degree images & 40x magnification, for every single diamond.

The Purchase, Checkout and Support

Buying a diamond at JamesAllen is pretty easy and straight-forward. The checkout process isn’t convoluted but, like any online checkout, there are probably a few too many clicks you have to make to get to the end.

You do need to create an account to checkout and complete your purchase but they offer a lot of payment options which was great. You can buy with:

  • Credit Card
  • Wire Transfer (with 1.5% off your purchase)
  • PayPal
  • SplitIt
  • In-House Financing

If you have specific questions about something it’s nice to be able to live-chat with someone from JA immediately, they have 24/7 chat support, and their customer service is spectacular, we’ve tried them more than once, but don’t take our word for it, give them a try yourself and see.

What’s even more is they employ GIA graduates as gemologists you can actually talk to before buying, so if you’re in doubt about a specific diamond and you want a GIA-level expertise, you can ask for that over chat.

Overall Recommendation

JamesAllen (along with their competitor Blue Nile) is a main pillar of online diamonds industry, they raised the bar and pushed competition in this industry on all fronts.

Whether you want to buy a diamond now, get an idea about diamond pricing, customize a ring with a rock, or even just wanted to explore diamonds beauty, JamesAllen is the store to go.

They are a great company to purchase diamonds and jewelry from, and they really seem to be confident in the products they sell and they want you to feel that.

If you want to buy a ring from JamesAllen, you won’t be disappointed. Ask them about return shipping and full refund policy, and you’ll likely also be pleasantly surprised.
