Bottom Line Recommendation

When you’re in the market for loose diamonds, you’ll almost always find better value and a greater range by shopping online. The advantages of shopping online are explored in-depth in this article.

It’s vital, however, that you choose a trusted vendor when shopping online. The best diamond retailers will offer a large range of high-quality diamonds at respectable prices. They should also offer the ability to inspect your diamond through high-quality images, so you know what exactly you’re getting for your money.

Here we’ll summarize the best places to buy diamonds online, and give a summary of what makes each retailer special.

The 5 Best Online Diamond Retailers

If you’re going to buy diamonds online, make sure you know which vendors can be trusted and which can’t.

Poor quality retailers may offer diamonds priced too high, a small range of diamonds on offer, or even diamonds that don’t carry certificates from reputable grading entities. This can lead you to spend a lot of money on a diamond that is worth a fraction of that price.

To ensure you have no post-purchase remorse, shop with a retailer that comes recommended across the diamond industry. Here are our recommended places to buy loose diamonds (click them to get to the proper section):

James Allen

Best for: all-round customer experience.

James Allen have established themselves as the go-to place to buy diamonds or diamond jewelry online. Everything they offer goes into providing the best customer experience possible and allowing you to walk away happy with your purchase. The technology James Allen provide on their site allows you to closely inspect every diamond, almost as if you were seeing it in person. Each diamond has a 360° high definition photo which can be rotated and magnified to see any small inclusion or flaw in the diamond.

On top of this, they offer a huge range of diamonds: more than 200,000 diamonds, conflict-free and certified by the GIA, AGS or IGI. They also happen to have one of the best ranges of loose lab-created diamonds, should you choose to go down that route.

Other hallmarks of the James Allen customer experience include superb 24/7 customer service, free worldwide and US shipping (each shipment is insured for extra peace of mind, and hassle-free returns within 30 days. All this makes them the first place you should go just about any time you want to buy a diamond online.

Blue Nile

Best for: selection.

Founded in 1999, Blue Nile was one of the first businesses to offer diamonds online. They began by operating on a business model that has been adopted by many other retailers since; they don’t carry stock themselves, instead, listing diamonds on their site that are being held with various manufacturers and wholesalers.

Blue Nile’s relationships with these suppliers allows them to offer an unparalleled range of diamonds, at competitive prices.

They also have the customer experience covered, with 24/7 expert advice, 30-day returns and lifetime guarantees.

The technology side of their shopping experience has also advanced massively in the last 10 years, with more than 60% of their inventory offering high-quality 360° images, helping ensure you pick a diamond that is eye-clean.

Blue Nile Round cut diamond

Their prices are competitive and much better than if you were to buy a diamond from a physical retailer.

Abe Mor

Best for: high-end diamonds, and loose melee diamonds.

Abe Mor is a diamond wholesaler, who buys and sells loose diamonds. If you’re looking to sell a diamond they are your best option, but they are also an interesting choice if you’re in the market to buy.

We’ll qualify by saying that Abe Mor is not the place to go for your everyday diamond buying. If you’re after a classic 1 carat diamond, the other names on this list are better to go for. However, for a high-end diamond and a bespoke experience, Abe Mor is a fantastic company.

They excel in rare and expensive diamonds – you’d generally consider this option if your budget is over $50,000. Abe Mor is excellent at sourcing large diamonds, where the choice on sites such as James Allen and Blue Nile may be more limited.

They also offer rarer diamonds, such as old mine cuts and old European cuts.

Abe Mor is also one of the few places that stock loose melee diamonds, however, this is unlikely to be a concern for everyday retail buyers.

Leibish & Co

Best for: fancy colored diamonds.

Leibish & Co are one of the oldest names in online diamond sales, having been selling to consumers online since 1995. Where they differentiate themselves from all other diamond sellers is their range of fancy colored diamonds.

If you’re in the market for a fancy color diamond, Leibish & Co are without a doubt the number one place to look. At many places, your options for colored diamonds are limited. James Allen and Blue Nile do stock a selection of fancy colored diamonds, but it’s nothing like the range that Leibish & Co offers. This is their bread and butter.

They are the best in this category for several reasons:

  • Their range is the best.
  • Their diamonds come with high-quality images (a must when buying online, and not always available for fancy colored diamonds at other retailers).
  • Being a name that is synonymous with fancy colored diamonds, their expertise in this area is better than anyone else.

The range Leibish carries includes the more common canary yellow diamonds, bold and unique black diamonds, and even incredibly rare and valuable pink diamonds and chameleon diamonds. As well as everything in between, of course.

Simply put, for fancy color diamonds, Leibish is the best.

Brian Gavin Diamonds

Best for: high-quality cuts.

Brian Gavin Diamonds is the best place to go for a truly spectacular cut. The name behind the company, Brian Gavin is one of the industry leaders in diamond cutting, and has been since the 1990s. Any diamond you purchase from Brian Gavin Diamonds comes with the same perfectionism with which Brian’s name is synonymous.

See these examples of the superb diamond cuts from Brian Gavin:

Brian Gavin Diamonds Round cut
Brian Gavin Diamonds Cushion Cut

As Brian Gavin Diamonds is a vendor that actually holds their own inventory (unlike virtual listers such as James Allen and Blue Nile), they are forced to concede somewhat on range and price. Thus Brian Gavin is not for everyone. If you’re looking to sacrifice on cut to get a bigger diamond for a better price, a vendor like James Allen is a better choice. But for top-end craftsmanship, and the service to match, Brian Gavin is your choice.
