Diamond Necklace Price | How Much Should You Expect to Pay?

There’s arguably nothing as elegant as a diamond necklace. It makes such a timeless statement necklace for a fancy night out and a gorgeous gift for a significant other, sister, or mother.

But it sure comes with a price, a steep one, might we add! Did you know that the most expensive necklace in the world is over $200 million!? But don’t worry because you can find ones for way less.

If you’re considering buying a fine diamond necklace or you’re just curious about its cost, this article is for you. We’ll cover everything you might want to know about the diamond necklace price range.

How Much Does a Diamond Necklace Cost?

Diamond necklaces can cost an average of $500 to $36,000 or more if you purchase a truly rare piece. If you go for a necklace with one small diamond, that’ll cost at least $250. Otherwise, necklaces with many diamonds surpass the $30,000 mark.

With that in mind, you’ll have a basic idea of the diamond necklace price range. Still, we can’t ignore the wide range of prices, which might get you to wonder about the factors contributing to that range.

Number of Diamonds

As you’d expect, a significant pricing factor is the number of diamonds in a necklace. Generally, the more diamonds a necklace has, the more expensive it is. But the “3 c’s” criteria, which we’ll detail below, can make it so that a single-stone necklace is very pricey as well.


Quality is probably the most significant factor, and we’re referring to the quality of the chains and diamonds. Concerning the chain quality, a reasonably-priced quality necklace can cost $1,000 to $6,000. Otherwise, 18k gold and platinum come with hefty price tags, and 14k necklaces are much less costly.

As for the quality of the diamonds, you can distinguish a top-notch diamond from a mediocre one by factoring in the “4 c’s”, which are:

1. Cut

The cut of a diamond refers to the quality of the angles, symmetrical facets, final details, and so on. A skillfully cut diamond features facets (cut surfaces) that reflect as much light as possible. As a result, a diamond’s cut contributes to its beauty and spark.

2. Color

This criterion refers to how colorless or white a diamond is. The Gemological Institute of America (GIA) has a quality grading system that labels diamonds with any letter from D to Z.

On the one hand, D is the most colorless and valuable. On the other hand, Z diamonds have a clear brown or yellow tint and are less valuable. Other than that, there are diamonds with unique and rare colors, such as red, blue, or green. Undoubtedly, their rarity makes them incredibly valuable.

3. Clarity

This rating scale can tell you how clear a diamond is. The fewer internal marks or inclusions and external marks or blemishes a diamond has, the more clear and valuable it is. So, the clarity of a diamond can range from “Flawless” and “Internally Flawless” to “Inclusion 1” and “Inclusions 2”.

4. Carat

Carat is a method of diamond weight measurement. A Carat Diamond is equal to 200 milligrams. Note that the size of a diamond doesn’t always reflect its weight. Accordingly, weight shouldn’t be the most prominent criterion of assessment. Nevertheless, high Carat diamonds hold more value than average ones.

Types of Diamond Necklaces

There are numerous types of diamond necklaces, but here are the main ones:

Diamond Pendant Necklace

Diamond pendant necklaces are trendy because of how easy it is to pair them with a casual outfit. They feature a main gemstone attached to the chain with a loop. The setting can be a single diamond or a main stone surrounded by smaller diamonds. Moreover, those pendants come in various diamond shapes, styles, and sizes (see cross necklaces).

But let’s touch on the cost of a diamond pendant necklace. A small dainty 1/4 carat pendant can be $300, whereas a big pendant with many diamonds can be $10,000.

As a type, we can classify pendant necklaces into several sub-types. For instance, we have:

  • Solitaire: A solitaire pendant necklace has a single diamond set on a chain in a prong setting. It’s elegant and stylish. Not to mention, the solitaire pendant piece has an open setting to allow plenty of light and spark.
  • Heart: As usual, a diamond heart necklace symbolizes love and is very popular. It makes for an excellent gift as well.
  • Floating: A floating diamond necklace features one stone, big or small, suspended from a dainty chain. Its style is both simple and classy.
  • Three-Stone: You’d be right to assume that a three-stone diamond necklace features three stones dangling from a chain. Also, they may or may not be in a vertical drop-like design. This necklace style is very ornate and intricate.

True Necklace

Where diamonds hang freely from a pendant necklace, they’re strung and secured to the chain or strand of a true necklace. These necklaces come in different lengths, widths, and designs. You can wear a full diamond necklace to a formal event or fancy occasion if you want to glam up.

As for the cost, such necklaces tend to cost a good fortune because they typically require many gemstones and diamonds. For example, a diamond tennis necklace adorned with small diamonds can cost anything from $950 to $50,000. And other more gigantic true necklaces can cost millions of dollars!

Much like diamond pendant necklaces, true necklaces also have several subtypes.

  • Tennis: A tennis necklace is encrusted with a set of small stones across its string. With so many gemstones, a tennis necklace is typically costly. But it’s the jewelry piece you wear to turn heads!
  • Choker: If you’re looking for a more modern style, consider a diamond choker necklace, which hangs tightly around your neck. It also costs more than a pendant diamond necklace.

The Diamond Necklace Buying Guide: Best Places to Buy

If you want to purchase the perfect diamond necklace, you need to find the right stores. Here are some of our favorite jewelry shops:

James Allen

James Allen is probably the number one online retailer of diamonds and jewelry. Its high-resolution photography allows you to turn a jewelry piece 360 degrees and get a good virtual look at it.

Aside from its spectacular online experience, the James Allen store offers you a wide selection of preset necklaces, but you can create your jewelry design. In other words, you can select your desired carat, color, clarity, and cut. Not to mention, you can pick a metal, whether that’s yellow gold, platinum, rose gold, or white gold. Nonetheless, not every metal is available for every design, so keep that in mind.


Zales is another popular option with a physical location and an online store. It has diverse options, including pendants, rings, earrings, and other jewelry pieces.

With its customization feature, you can create beautiful diamond necklaces by choosing your carat and metal, whether that’s sterling silver, platinum, or else. Even better, the online shop enables you to simulate the personalized styles you have in mind. But if you visit the shop, take care not to pick up a jewel or stone with natural inclusions and blemishes.

For one, the Fancy Yellow Cluster Cushion Necklace is a stunning piece from James Allen with 18k white and yellow gold. Its round diamonds sparkle, giving you an elegant glow.

Also, we’re in love with this Diamond Graduate Riviera Necklace from Zales. It’s made of 10k white gold. The graduation from the largest to the smallest diamonds gives this necklace the wow factor you’re in search of.

Final Thoughts

Overall, diamond necklaces vary significantly in their cost, costing anything from $500 to $36,000. That’s because some necklaces, such as pendants, may feature a single diamond, whereas other necklaces, primarily chains, chokers, or so, get encrusted with various diamonds.

Not to mention, even the quality of the diamonds differs. Some are more heavy, clear, colorless, and accurately cut than others, making these diamonds way more valuable and costly.

The biggest takeaway is to make note of such factors when debating the cost of a diamond necklace. Knowing what you can get with your budget will facilitate the shopping experience, make it more fun, and get you a great deal!
