Blue Nile Review - Bottom Line Recommendation

Searching for Blue Nile lab diamonds? They don’t sell loose lab-grown diamonds or engagement rings with lab diamonds as a center stone. If this is what you are interested in, you should check James Allen and Brilliant Earth. In short, Blue Nile’s agenda is against lab-grown diamonds, which is why they promote them only for everyday jewelry. Above all, they don’t really see them as an alternative product for natural diamonds because it’s bad for their business.

To sum up, their lab-grown jewelry collection is very generic and small. For that reason, I don’t see any reason to buy from them when you can buy beautiful and unique jewelry from this retailer.

Blue Nile is one of the most popular online diamond retailers. They are known for their large selection of natural diamonds and competitive prices. However, they do not offer lab-grown diamonds for engagement rings. In this review, we will look at Blue Nile’s lab-grown diamond inventory and agenda. After reading this, you’ll know if Blue Nile is the right fit for you.

Blue Nile lab-grown diamonds

Does Blue Nile Sell lab diamonds? Yes and no… Depending on what you are looking to buy.

First of all, I have bad news for those of us looking to get an engagement ring with a lab-grown mounted from Blue Nile. They didn’t jump yet into the lab diamonds world. But why? Well, the answer is quite simple. The lab-grown diamond niche divided the diamonds industry into two groups:

  1. Those who support affordable and alternative products.
  2. Those who stand against any alternative for natural diamonds.

The agenda is straightforward. Suppose more and more customers will buy lab diamonds instead of natural diamonds. In that case, the demand for natural diamonds will decrease, and so will their prices. 

The leading company that stood against the entrance of lab-grown diamonds into the market is De Beers, one of the largest mining companies in the world. I have a reason to believe they made Blue Nile stay away from loose lab-grown diamonds.

Let’s spill the tea.

De Beers wanted to make lab-grown diamonds look cheap in the eyes of the everyday consumer. So what did they do? They created a company called “Lightbox Jewelry.” Overall it looks like a friendly company with excellent branding, BUT! They only sell lab-grown diamond jewelry: Earrings, bracelets, and necklaces. No loose lab diamonds, no engagement rings. Their salty message is clear: Lab diamonds are cheap; as long as you buy them for everyday jewelry, we are fine. Yet, lab diamonds for engagement rings? Not allowed.

Certainly, we know Blue Nile took De Beers’ side because the only lab-grown diamonds they offer are made by Lightbox Jewelry. Blue Nile’s CEO also said it loud and clear in an interview on Fox news.

Did their shady plan work? I don’t think so.

Meanwhile companies such as Brilliant Earth and James Allen are on the rise, growing and selling lab-grown diamonds, Blue Nile is sitting on the bench and losing momentum.

Blue Nile lab diamonds selection and Lightbox Jewelry

Blue nile lab-grown diamond selection is minimal, and that’s an understatement. Their inventory is built over Lightbox Jewelry products: pre-made earrings, bracelets, and necklaces. Since they have an agenda against lab-grown diamonds for engagement rings, you won’t find any loose diamonds. You won’t be able to pick your own lab diamond like you can find here.

If you are looking for a loose lab-grown diamond, I recommend checking James Allen and Brilliant Earth. They offer a wide selection of lab-grown diamonds (over 20,000); each is photographed and comes with a 360HD video. This way, you can inspect the diamond and pick the best one. If you need help, contact me here and let’s find the right diamond.

Both also offer a wide variety of lab-grown jewelry. Let me tell you a secret, Brilliant Earth is my recommended retailer for lab-grown jewelry. They pay attention to little details, and every piece of jewelry they offer is stunning and affordable.

James Allen vs. Blue Nile

Unlike Blue Nile, James Allen offers over 20,000 loose lab-grown diamonds, from 0.3 carat to 5.00 carat, in a wide range of colors and clarities. Doesn’t matter if you have a $1,000 of a $30,000 budget; you’ll find your lab-grown diamond there. But not only that, James Allen also wins in the natural diamonds’ battle. They currently offer over 500,000 diamonds at a much better price than Blue Nile. The only niche that Blue Nile wins is in its natural diamonds and gemstone jewelry (earrings/bracelets/necklaces). Seems like they know they lost the engagement ring battle against James Allen, and now go All In with their jewelry game.

Brilliant Earth vs. Blue Nile

Like James Allen, Brilliant Earth is one of the market’s largest and most well-known lab-grown diamond online retailers. They offer an extensive inventory at competitive prices. But here is the twist. In my taste, Brilliant Earth cast a shadow over Blue Nile with their jewelry collection. They pay attention to little details and sell stunning designs at competitive prices. Similarly, they put all their heart and soul in their engagement rings.

You can find there anything: Natural and lab-grown diamonds, fancy colored diamonds, and a gorgeous collection of gemstones.


I think it’s pretty clear that Blue Nile is not the right place to buy your lab-grown diamond. They have limited products and don’t offer loose lab diamonds for engagement rings. James Allen and Brilliant Earth are the ideal alternatives for Blue Nile if you are on the hunt for the perfect lab-grown diamond, so check them out and feel free to reach out and have me on your side.
