When it comes to buying a diamond necklace, the most asked question by our customers is, ‘How much does a diamond necklace cost?‘ Well, the answer depends on various factors. These factors include whether the necklace is made with natural or lab-grown diamonds, the cut quality, the carat weight and more. Depending on these factors, their prices can vary from hundreds of dollars to thousands. Before you make a final choice, it’s essential to understand what you are paying for.

That’s why here in this guide we will talk about real prices of diamond necklaces (natural vs lab), real market examples, expert insights and much more. So in order to make an informed decision, stay with us.
What Is the Average Diamond Necklace Cost?
According to the Gemological Institute of America (GIA), the average cost of a diamond necklace is determined by the 4 Cs of gems. These include the cut, colour, clarity, and carat weight of the gem. According to our experts and listings from major US retailers, the prices vary from as low as $300 to as high as $8,000.

But the luxury of diamonds can reach higher than $50,000. This depends on the necklace style, either a chain necklace or a classic gold pendant. International Gem Society suggests that lab-grown diamonds are about 60% cheaper than lab grown one. Here is the detailed breakdown of average prices of your fine jewelry neckwear.

Here is the table illustrating the average price of different necklace styles in our collection:
| Type | Average Price | Typical Carat Weight | Common Metal | Key Characteristics |
|---|---|---|---|---|
| Lab Diamond Pendant | $300 - $1,500 | 0.25 -0.75 ct | 14K or 18K gold, sterling silver | Contains a single lab-grown diamond on a simple chain. Considered unisex and loved by both men and women for elegance. |
| Natural Diamond Pendant | $800 - $5,000+ | 0.25 -1 ct | 14K or 18K gold, platinum | Features a naturally mined diamond. Purchased for anniversaries or milestone gifts. |
| Lab Diamond Tennis Necklace | $2,000 - $8,000 | 5 - 15 total carat weight | 14K or 18K gold | A continuous line of lab-grown diamonds around the neck. |
| Natural Diamond Full Necklace (Tennis or Multi-Stone) | $8,000 - $50,000+ | 10 - 30+ total carat weight | 18K gold or platinum | High-end necklace featuring multiple natural diamonds. Often considered luxury jewelry pieces. |
What Determines the Price of a Diamond Necklace?

When you are searching for the right neckline piece, you must choose one design that is according to your budget and personality. So you must know how the pricing for these neck pieces works. Here we have categorised the main ones.
1. Natural vs Lab Diamonds
One of the most debated factors that determine the pricing is the source of the diamond, whether it’s natural or lab-grown. One thing our expert guaranteed is that lab-grown diamonds are real diamonds with same chemical or physical properties.

The only difference is how they are made. For a natural diamond, it takes millions of years to grow, and discovering a big one is also difficult. However, you can create same diamond in a lab in just a few weeks using advanced techniques. Because of the rarity, the natural one is 40-70% more expensive even though both are visually identical.
Resale Value Difference

Natural diamonds traditionally hold stronger resale value, about 30 % to 60 % of their original retail price, while lab diamonds are popular for buyers who want a larger stone at a lower cost. However, lab-grown often resells for less because the supply continues to grow and manufacturing costs are dropping.
2. Carat Weight (Most Important Factor)
Carat weight is usually the biggest factor adding to diamond necklace costs. As the carat size increases, the price rises significantly. It’s because larger diamonds are rarer.
Common categories and design include:

- 0.5-carat necklace: It’s perfect if you are looking for an affordable option. It is used in men’s and women’s or unisex pendants. You can choose it as sending a luxury gift.
- 1-carat necklace: Our experts suggest that it’s a classic and perfect balance between size and price.
- 3-carat pendant: We consider it a luxury statement piece, as its price is high due to its large size.
- 10-carat tennis chain: This chain is a perfect example of the most luxurious jewellery pieces. Its design carries multiple diamonds across the chain.

We suggest that if you are searching for something elegant yet practical, you choose necklaces between 0.5 and 1 carat. Since these necklaces provide noticeable brilliance without extremely high costs.
3. Diamond Quality (4Cs Simplified)
Diamond quality is determined by the cut, clarity, colour and carat weight. But what do these actually mean? Let’s simplify these factors:
Cut: How your diamond reflects light is determined by its cut quality. If our diamond is created by an expert, it will have a perfect cut for elegance, sparkle and design.

Colour: Colour is not a property of diamonds. That’s why diamonds with less colour are typically more valuable.
Clarity: A diamond with fewer internal inclusions means a higher value.
Carat: Refers to the diamond’s weight.
You must apply these quality filters while picking up your favourite diamond necklace.

4. Pendant vs Full Diamond Necklace
The design and structure of the chain also determine the pricing. There are two major categories.
Diamond Pendant

The chain carries one single diamond. You can pick a small one, for instance, 0.25 carat for an elegant look or 1 carat for luxury. It usually comes in gold or silver metals. According to our designers, pendants are unisex; both men and women love to adorn them.
Full Diamond Necklace

Such necklaces carry a number of small diamonds, from a few to hundreds. It’s also unisex when it has just a single strip with multiple small diamonds. As it carries a greater number of diamonds, that’s why it’s expensive.
Real Diamond Chain vs CZ vs Moissanite
If you are a first-time buyer of diamonds, you might get confused between diamonds, CZ (cubic zirconia) or moissanite. That’s why knowing the difference is important so you may not fall for fake necklaces with lower pricing. Here is the difference in pricing, originality, and characteristics:
| Type | Is It a Real Diamond? | Price Range | Typical Carat Weight | Common Metal | Durability |
|---|---|---|---|---|---|
| CZ (Cubic Zirconia) | No | $50 -$300 | 1 - 5 ct (simulated) | Sterling silver, plated gold | Low |
| Moissanite | No | $500 - $2,000 | 0.5 - 2 ct | 14K/18K gold, platinum | High |
| Lab-Grown Diamond | Yes | $2,000 - $8,000 | 0.5 -3 ct | 14K/18K gold, platinum | Very High |
| Natural Diamond | Yes | $8,000+ | 0.5 - 10+ ct | 14K/18K gold, platinum | Very High |

Natural vs Lab Diamond Necklaces: Price, Look & Long-Term Value
Are lab diamonds real?
Yes, lab diamonds are definitely real diamonds with same optical, physical and chemical properties. The only thing that makes them different is the way they are grown.

Do they pass diamond testers?
Lab diamonds come with laser etching, and they pass the diamond testers. Only a well-experienced jeweller with specialised equipment can identify them.
Are they visually identical?
Yes, natural and lab-grown diamonds are 100% visually identical to the naked eye. No one, not even experts, can tell the difference with the naked eye.

Why are they 40–70% cheaper?
Lab diamonds are cheaper because they can be produced according to the demand. You can get same-size diamond cuts within a few weeks compared to natural ones that will take years to grow. Not only does this lab-grown meat not involve a mining process as well.
Resale value comparison
When it comes to resale value, definitely natural diamond necklaces take the edge, keeping their 50 to 60% resale value. However, lab-grown have a very low RSL value, about 20 to 30% of their actual price.
Are Lab Diamond Necklaces Worth It?

The worth of a diamond necklace depends upon the buyer’s mindset. For example, if someone is looking for smart use of Oneya and just wants a diamond for fashion, he should opt for lab-grown. Whereas the one who is viewing a diamond as an investment should opt for a natural one. Because natural one has low retail markup loss. The only diamonds, which are very rare, hold max value, which increases with time.

Diamond Chains in Hip-Hop Jewelry
Hip-hop culture has a special place for diamond necklaces. Artists used to wear them to show their class, elegance and success. The two most worn chains in hip hop in the 1980s and 1990s were the iced-out pendant and the Cuba link chain.

An iced-out pendant refers to a pendant that is completely covered with hundreds of small diamonds across its surface. Whereas a Cuban chain features thick, interlocking links. Such links create a strong, bold appearance. When diamonds are added to each link, the chain becomes a luxury statement piece.
Lab diamond vs moissanite
According to our experts’ experience, when buyers look for chains in hip-hop jewellery style, they can get them in both natural and lab-grown diamond forms.
Lab-Grown Diamonds

- Real diamonds with the same chemical structure as natural diamonds

- Stronger long-term value
Moissanite

- More affordable but not a real diamond
- Lower resale potential

Diamond Necklaces

Diamond necklaces come in various diamond cuts and settings with specific certifications and budgets. Before you make a decision, it’s important for you to know these cuts, settings and budget. So let’s explore it:
Diamond cuts used in necklaces

The cut of a diamond is one of the most important factors influencing the beauty and price of a diamond necklace. Diamond cut refers to how well a diamond is shaped and faceted to reflect light. A well-cut diamond enhances sparkle, brilliance, and overall design appeal.
Round Brilliant Cut

The round brilliant cut is the most popular diamond shape. It is designed with 58 facets. These facets allow the diamond to reflect maximum light and sparkle. We prefer to use this cut in our solitaire pendants and tennis necklaces
Princess Cut

The princess cut is a square-shaped diamond. It is known for its sharp corners and modern look. It has a square shape with a strong sparkle. The princess cut is preferred in modern pendant necklaces.
Oval Cut
The oval cut diamond has an elongated shape. This shape makes the stone appear larger than its actual carat weight. Customers who want an enhanced visual length opt for this cut.

While many diamond shapes exist, round, princess, oval, and cushion cuts remain the most common. The best cut depends on personal style, budget, and the overall design of the jewelry piece. We believe that a well-cut diamond can significantly enhance the brilliance and elegance of any necklace.
Common necklace settings
Not only are there cuts, but diamond necklaces are also available in different settings. Let’s get to know about them:
Sterling Silver Necklaces
Sterling silver necklaces are durable and brighter. Our sterling silver has 92.5% pure silver and 7.5% alloy metals. You can pick a lab diamond sterling silver necklace within your budget.

Yellow Gold Necklaces
Yellow gold is considered a traditional metal for diamond necklaces. It can be 10K, 14K, 18K, and 24K; you can pick according to your budget.
Rose Gold Necklaces
Rose gold is the result of mixing yellow gold with copper. It makes it a softer appearance. Such diamond necklace can be wear using cushion, or halo diamond pendants

White Gold Necklaces
Last but not least, the most popular diamond necklace setting is white gold. It is made by mixing yellow gold with white metal. Its sparse appearance enhances the diamond’s natural appearance.

- Is it lab-grown or natural?
- Do your diamonds have certifications with GIA or IGI?

- If you want everyday luxury pick lab pendant within $1,000 to $2,000 range
For a hip-hop statement you can choose a lab-iced chain. It will cost from $3,000 to $8,000
Finally, if you want an heirloom, your perfect choice would be a natural diamond. For this you mus have a budget of $8,000+
