Tiffany vs. Blue Nile

If you’re buying a diamond ring or another piece of jewelry, there are plenty of online and in-store retailers in the market.

Blue Nile and Tiffany are two of the most prominent, though they offer unique buying experiences and products.

Based on their wide selection of jewelry, quality prices, and exceptional buying experience, we recommend Blue Nile.

But let’s compare Blue Nile versus Tiffany across the areas most important to buying jewelry, such as their selection, quality, price, return policies, and more.

Blue Nile: Overview

Blue Nile Retail Store

Blue Nile is an online jewelry retailer known for its wide selection of engagement and wedding rings, necklaces, bracelets, and more. They’ve recently opened physical retail stores.

It was founded in 1999 and is based in Seattle, Washington.

Shoppers used to rely on a personalized, in-store experience when purchasing such expensive pieces of jewelry. 

Blue Nile pioneered the online buying experience in an industry formerly dependent on brick and mortar retail. 

Due to its success, other online diamond vendors such as James Allen and Brilliant Earth have entered the market.

Blue Nile prides itself on working directly with manufacturers and wholesalers to offer customers  a low price. With minimal overhead and fewer parties involved in the transaction, they avoid the high markups of other retailers.

The company also promotes its diamonds as conflict-free and follows the Kimberley Process of identifying and sourcing diamonds.

You can read the full history of the company on their website here, or check out our extensive Blue Nile review.

Tiffany’s: Overview

Tiffany's Retail Store

Tiffany & Co, known as Tiffany’s, is a luxury jeweler headquartered in New York City. 

It’s primarily known for its engagement rings and the Tiffany setting, which is a six-prong solitaire setting designed to maximize the prominence of the center diamond.

Other retailers offer a similar design, but Tiffany patented its version of this setting.

 It also sells other jewelry such as:

  • Necklaces and pendants
  • Bracelets
  • Earrings
  • Sterling silver
  • Watches

Tiffany’s was founded in 1837 by Charles Lewis Tiffany and today has more than 300 stores around the world.

It began offering its products online as the idea of selling jewelry through a website became more commonplace. 

It’s still known for its in-store experience, but you can also find a wide selection online and have it shipped to you.

Like Blue Nile, Tiffany’s only sells conflict-free diamonds and abides by the Kimberley Process.

What are the Differences Between Blue Nile and Tiffany?

Deciding on a Blue Nile versus Tiffany’s diamond, engagement ring, or other piece of jewelry involves understanding how each compares across the entire buying experience. 

It begins with exploring their options and continues through purchasing the product and learning about warranties and return options.

We’ll examine each of these and more in detail.


Blue Nile has a much wider selection of diamonds than Tiffany’s. 

In fact, Tiffany’s doesn’t sell loose diamonds. Instead, they’re only available as part of rings.

Blue Nile has more than 350,000 round-cut diamonds across all carats, colors, cuts, and clarity grades. You can view the full selection on their “Diamond Finder” page.

Blue Nile Diamonds

It sells more than 34,000 emerald cuts, 13,000 pear cuts, and 3,000 radiant cuts.

Tiffany’s selection in the engagement ring category also pales compared to Blue Nile.

In the “Engagement Rings” section of their website, there are only 53 options. 

Tiffany's Engagement Rings

Variations include:

  • Platinum, 18k, and rose gold settings 
  • Cushion cut diamonds surrounded by a halo
  • Settings with pave diamonds down the shank
  • Three-stone engagement rings with pear-cut diamonds on the sides

Tiffany’s allows you to customize an engagement ring by pairing a diamond with more than 20 types of settings in platinum or rose or yellow gold.

But Blue Nile’s customization options allow you to do the same with all its loose diamonds and any type of shank

For example, we often point readers toward their line of halo settings, like this platinum design.

The same idea is true for wedding rings. On its website, Tiffany’s lists 129 variations in gold, sterling silver, titanium, and more. 

Some feature diamonds or rubies, and others are knife edge rings.

Blue Nile’s selection of wedding rings includes more than 1,000 variations across cobalt, titanium, tungsten, and more. There are 14 distinct styles such as channel-set, eternity, and vintage.

One of our favorite lines is their micro pave, half-eternity rings, like this one.

Whether you want your wedding ring to shine like your engagement ring, or want a simple band without sparkle, you can explore every type at Blue Nile.

So if you’re looking for which diamond store has the most choices, we recommend Blue Nile over Tiffany’s.


You shouldn’t judge the quality of a diamond based on the vendor, whether it’s Blue Nile, Tiffany’s, James Allen, or Zales.

Instead, it should be evaluated by a reliable third-party organization such as the Gemological Institute of America (GIA) or American Gem Society (AGS), so you can be confident in its traits.

All Blue Nile diamonds are assessed by the GIA, and they often include a copy of the report on its website. This is a feature that makes Blue Nile one of our recommended vendors.

Select a loose diamond, scroll down, and click “View Report” under the GIA logo.

GIA Report on Blue Nile

It will show its clarity, cut, carat, and color, in addition to other important measurements such as:

The GIA applies its rigorous standards to each of these areas. If the report rates it highly across many of those characteristics, you can have confidence in its quality.

Tiffany’s diamonds don’t come with GIA reports. Instead, Tiffany’s has its own grading lab. Grading diamonds in-house is often viewed as a conflict of interest. 

The company has incentive to grade diamonds higher than a third-party institution would, so the diamond will sell at a higher price.

That being said, Tiffany’s is known to use high standards. It may not live up to the standards of the GIA or AGS, but it often exceeds those of less reputable organizations.

For example, they only sell diamonds in the “near colorless” or “colorless” ranges. This often means any yellow tints aren’t visible to the naked eye.

The same idea is true for clarity. Tiffany’s says they won’t sell diamonds that have inclusions visible to the naked eye. This is known as an eye-clean diamond.

Whether you’re buying a diamond from Tiffany’s or Blue Nile, don’t determine its quality based on the brand. Examine the grading report to learn its traits.


Tiffany’s diamonds are more expensive than ones from Blue Nile. If you compare diamonds from each retailer, Tiffany’s diamonds often cost twice as much.

For example, let’s compare the prices of Blue Nile and Tiffany’s engagement rings with a solitaire setting and a diamond with the following traits:

  • Carat weight: 1.01
  • Color: H
  • Cut: Excellent
  • Clarity: VVS1

At Tiffany’s, this engagement ring sells for $14,600.

Tiffany's Engagement Ring

At Blue Nile, this engagement ring sells for $7,356.

As another example, this engagement ring from Tiffany’s includes pave diamonds on the shank. It sells for $21,000.

This ring from Blue Nile also has a platinum band with pave and the same quality diamond on top. Its price is $7,696.

When comparing the prices of Blue Nile versus Tiffany’s diamond rings, you can save a significant percentage by ordering the same quality ring from Blue Nile.


The reason Tiffany’s diamonds are so much more expensive than ones from Blue Nile, even if they’re the same quality, is because of branding.

Tiffany’s knows jewelry shoppers aren’t only buying a ring. They’re often buying a status symbol and want a strong brand associated with their jewelry.

That’s why Tiffany’s has spent decades, and millions of dollars, creating a sought-after brand that stands for quality. It’s why their pieces come in that iconic blue box.

Tiffany's Blue Box

They want to convince you that you aren’t only buying jewelry. You’re buying luxury.

So their jewelry commands a premium price compared to many other online and in-person retailers.

Blue Nile, on the other hand, brands itself as offering a smooth online shopping experience and low prices. 

By working directly with wholesalers and manufacturers, they’re less concerned with building a luxury jewelry brand and more concerned about affordable, quality diamonds.

As a result, their margins aren’t as high.

If you’re focused on value, choose Blue Nile over Tiffany’s. 

But if you want a premium brand that adds a sense of luxury to your purchase, Tiffany’s offers this experience.

Customer Service

When you’re buying an expensive item like an engagement ring, you expect excellent customer service from the beginning to the end of the buying experience.

Both Tiffany’s and Blue Nile promote their quality customer service, but each offers it in a different way.

To categorize them broadly, Tiffany’s wants to offer a personalized buying experience, while Blue Nile’s business model is more about allowing the customer to handle the transaction themselves.

What we mean by that is Tiffany’s in-store experts can walk you through buying a piece of jewelry, explaining its qualities such as cut and clarity, and allowing you to view the piece in person.

Blue Nile and many of their online alternatives allow you to create your engagement ring online, and they’ll ship it to you.

Blue Nile Buying Experience

You don’t have to interact with anyone on their team throughout the process, though they’re available by chat, email, or phone to assist you.

Recently, they’ve expanded their footprint beyond their online store and built physical retail stores, but the vast majority of their business is still done online.

Tiffany’s customer service department offers many of the same features as Blue Nile’s, but they pride themselves on that one-on-one experience.

If you’re looking for an efficient buying experience that still offers comprehensive customer service when you need it, Blue Nile fits the bill. 

If you want a personalized experience in selecting the perfect diamond ring, Tiffany’s could be the right fit, but you’ll pay a premium.

Returns and Warranty

Jewelers know their pieces are often too expensive of a purchase for their customers to be anything but satisfied. 

That’s why Tiffany’s and Blue Nile both offer returns and warranties, but it’s important to know the details of those policies.

Tiffany's Warranty

Tiffany’s offers refunds for items returned within 30 days, and they’ll pay for the shipping. 

They don’t provide refunds for engraved items, so if the setting has a few words engraved inside, you won’t get your money back for it.

You can read Tiffany’s complete return policy here.

Blue Nile also requires you return the item within 30 days, and they’ll send a shipping label. Similar to Tiffany’s, they don’t offer returns on engraved items.

You can read Blue Nile’s complete return policy here.

Both companies provide warranties, and there’s not much difference in coverage between Blue Nile and Tiffany’s.

Tiffany’s offers free cleaning and polishing for the life of the ring. For repairs, you can send in your ring, and they’ll provide a free estimate. 

Tiffany's Ring Repair

It also comes with a ring upgrade program, where you receive a credit for your original purchase when buying the new one.

Blue Nile offers a lifetime warranty with an upgrade program and free cleaning. 

If your piece has a defect from manufacturing, it can be returned for an inspection. From there, they’ll either replace or repair it.

This warranty doesn’t include the slight irregularities or variations that result from the craftsmanship or natural characteristics such as inclusions.

The company says it’s part of the natural characteristics of the diamond and isn’t considered a defect under its policies.

Reviews from Customers

It’s not enough to read what companies promote about themselves on their website. Where you learn whether they live up to those promises is to read what customers have said and wrote about them.

Blue Nile boasts an A+ rating from the Better Business Bureau (BBB). 

That doesn’t mean they’ve never received a bad review from customers, but it does mean they take complaints seriously and connect with customers to resolve them.

Tiffany’s has also earned an A+ from the BBB, so if you have an issue, you can be confident the company will at least try to resolve it.

Other online review platforms are less kind to Tiffany’s. 

For example, they have 2.1 out of five stars on their TrustPilot.com profile from 260 reviews. 

Tiffany's Customer Reviews

Common themes include customer service teams that are slow to respond and feeling the quality of the jewelry doesn’t live up to its price.

On the other hand, customer reviews on Tiffany’s Consumer Affairs page are more positive at four out of five stars from 175 ratings. 

Feedback includes the high degree of sparkle in the diamonds and the quality of the in-store experience.

The overall online sentiment toward Blue Nile is more positive versus Tiffany’s. 

Blue Nile Customer Reviews

For example, one reviewer on Reddit documents their experience of buying the wrong diamond. 

They sent it back, were provided the refund, and the customer service representatives were knowledgeable about the process.

Another reviewer wrote how it’s the right place to buy an engagement ring if you’re familiar with the four Cs of color, clarity, cut, and carat. 

If so, you might not need a jewelry expert to walk you through the process, so Blue Nile makes it easy.

Should you Buy a Diamond Ring from Blue Nile or Tiffany’s?

Blue Nile and Tiffany’s are two of the largest diamond and jewelry retailers and boast many satisfied customers. We’re confident you’ll be satisfied with both vendors.

But if you’re deciding between Blue Nile versus Tiffany’s, we recommend Blue Nile because of their quality inventory, low prices, and smooth buying experience. They’re one of the best online diamond stores.

As one of the first jewelers to popularize buying online, they have perfected the model across many different pieces.

They don’t offer the prestige of a brand like Tiffany’s, but many buyers are more concerned with value than luxury. 

But in the comparison with Tiffany, Blue Nile earns our recommendation.
