Lab-Created Diamond Pendant: Buying Guide

By Mike Fried,

The perfect gift for anniversaries, graduations, birthdays etc, diamond pendants are one of the most sought after gifts for our readers. Many of our readers have asked how they can get a larger diamond within their budget. The obvious answer is staring right at us: Lab-grown diamond pendants. Yes, this 3/4 ct diamond pendant from James Allen is incredible. But if you are deadset on getting a 1 ct pendant, you can get this 1 ct stunner from JA for the same price (even a bit cheaper) because the diamond is lab-grown.

” I think lab diamonds are here to stay and I think it’s a choice for the consumer to make, and it’s our job to educate them.… A lab diamond doesn’t say I love you any less than a mined diamond says I love you.” Beryl Raff, Former CEO of Helzberg Diamonds as reported in JCK Online.

What is a lab-created pendant?

A lab-created pendant is a necklace with a lab-grown diamond attached to a jewelry chain. The chains are usually made of gold or platinum. Styles range from simple and classic to ornate vintage designs. With lab-created pendants, the main difference is that they showcase a lab-grown stone instead of a natural diamond

Diamond pendant necklaces symbolize love. They’re often given to partners, mothers, sisters and other loved ones. 

To help you with the diamond buying process we lean on our expertise and experience. The author of this article, our CEO, Mike Fried has over 20 years of experience in the diamond industry. Mike started from the bottom, sorting and evaluating hundreds of thousands of diamonds to learn every facet (pun intended) of diamond quality and value. Mike followed that up by spending years buying and selling diamonds on the wholesale market as well as selling tens of millions of dollars worth of diamonds to diamond retailers.

Where to buy lab-created pendants

Like lab-created diamond rings, it’s important to buy a pendant from a reputable vendor. In our experience, many companies offer lower quality diamonds to achieve lower price points. You’re better off getting a good quality lab-created diamond for a higher price over purchasing a poor quality product. That’s why we recommend James Allen for lab-grown diamonds, including lab-created pendants (You can also check out other recommended vendors for lab-created diamonds.) They have a build your own pendant option that allows you to design the exact necklace you want.

2. Choose your precious metal

Lab-created pendants are often made of white gold, yellow gold, rose gold or platinum. All these precious metals are durable enough for everyday wear. 14K gold gives you the best value, as it’s beautiful and sturdy, but costs less than 18K gold and platinum. 

Opt for the color that matches her other jewelry or choose the tone that will stand out. The dropdown menu gives you your precious metal options for the pendant you selected.

3. Check out the 360° view 

Online vendors like James Allen provide high-quality HD imagery with a 360° view of your jewelry. Review all angles of your design to ensure it’s what you want. If you don’t like what you see, go back and select a different pendant design.

4. Add a lab-created diamond 

Once you’ve selected your pendant, it’s time to pick out your lab-created diamond to go in the necklace. As with a natural diamond, you’ll have the chance to pick the exact stone you want.

5. Narrow down the specs

To get the most beauty for the best price, it’s critical that you hone in on a lab-created diamond with excellent features without overpaying. 

Shape: Depending on your vendor, choose anything from a lab-grown oval pendant to a classic round cut. The diamond shape you select is based on personal preference. Round diamonds are the most popular, especially for pendants.

Carat: A diamond’s carat refers to its weight, not its size. You may have a certain carat in mind, but if not, leave the range open so you can see different options and prices. In general, a 0.9 carat diamond will look very similar in size to a 1.0 carat diamond, but could cost a significant amount less.

Cut: A diamond’s cut quality impacts its beauty more than any other feature. We recommend limiting your search to diamonds graded as Excellent or Ideal. 

Color: For lab-created diamonds, those within the G-J color range will appear white, but cost far less than D, E and F graded diamonds.

Clarity: Narrow your search to SI1 to VS1 lab-created diamonds. They will be eye-clean (meaning no inclusions can be seen with the naked eye) and cost much less than better-graded diamonds. But don’t forget to check the inclusions anyway. Don’t take the clarity grade for granted.

Filters on James Allen

Adjust the filters as you want, but the above image is what we recommend for lab-created diamond pendants. Increase the carat weight as you wish, knowing the price will increase too.

6. Compare lab-grown diamonds 

After you’ve narrowed down your diamond specs, compare similar stones to figure out which one to buy. Look at the 360° photo to see the diamond from all angles. Consider aspects like how brilliant the diamond is, if it appears white, and the cost.

Comparing lab-grown diamonds

Other details like polish, fluorescence, and symmetry affect a diamond’s appearance to some degree, but much less than the 4 Cs of diamonds. In general, you won’t need to worry about these features with a diamond pendant.

7. Select your diamond

Check out the loose lab-created diamonds in detail before choosing the one you’ll put in your pendant. Ensure that it’s IGI certified — the only certificate we recommend for lab-created diamonds.

Once you feel confident with your diamond, select it for your pendant.

8. Review your pendant

Lab-created pendant prices

In general, lab-created pendants will be less expensive than natural diamond pendants. Lab-created diamond pendants range from $700-7,000 or more, depending on the style, carat weight and precious metal. 

It’s important to note that lab-grown diamonds don’t have any resale value. So while they cost less, they’re usually less desirable and less valuable than natural diamonds. For those looking for an affordable alternative, a lab-grown diamond necklace is a fine choice. More people are open to a lab-created diamond for a pendant necklace than they are for an engagement ring.

FAQs About Lab-Created Diamonds

Most people are familiar with natural diamonds, not as many know about lab-grown diamonds. Here are some answers to common questions about lab-created diamonds. 

Are lab-created diamonds worth anything?

No, lab-created diamonds aren’t worth anything after you buy them, because they have no resale value. For instance, if you bought this 1.20 Carat lab-created diamond from Blue Nile, you’d have a beautiful diamond, but no jeweler will rebuy it. If you try to sell it on Craigslist or eBay, you’ll get pennies on the dollar. 

Are lab diamonds real diamonds?

Yes, lab diamonds are 100% real diamonds. They consist of carbon atoms structures and display the same chemical and optical characteristics of a natural diamond crystal. They don’t grow in natural conditions, as they’re made in a laboratory instead of found beneath the earth’s surface. Lab diamonds can be grown in a matter of weeks, while natural diamonds take billions of years to form.

Why do labs grow diamonds?

Labs grow diamonds because they mirror the same visual and chemical characteristics of natural diamonds. These diamonds are placed in jewelry, including lab-grown diamond necklaces and earrings. The process for creating lab-grown diamonds is much cheaper than mining natural diamond crystal. Some people also enjoy the engineered quality of lab-grown diamonds and prefer them to natural diamonds.

Does GIA certify lab-created diamonds?

The GIA certifies lab-created diamonds, but IGI is the recommended certificate for lab-created diamonds. They are more wide-spread and offer the same exact details that you need to make an informed decision.

How much are lab-grown diamonds?

The prices of lab-created diamonds can vary greatly. A lab-grown diamond can be priced as low as this 0.70ct G/VS2 Pear shape from Brilliant Earth for $770 or as high as this 7.08ct Round cut from James Allen for $80,390. Keep in mind that lab-created diamonds have no resale value. 

Lab-grown diamond prices depend on a few main factors: cut, carat weight, color and clarity. The better grades a diamond has, the higher the price.
