Lab-Grown Diamond Tennis Bracelets: Everything to Know

By Mike Fried,

A lab-grown diamond tennis bracelet is a timeless piece of jewelry featuring a single or multiple rows of lab-created diamonds set in a straight line. These diamonds are not mined but are instead created in a laboratory setting, making them an ethical and often more affordable choice without compromising on brilliance or quality.

Whether you’re looking for a bracelet for your wedding day or a special event, a lab-grown diamond tennis bracelet can offer brilliance and style. Lab-grown diamonds are less expensive than mined diamonds and look identical. Designs range from classic tennis bracelets to modern styles with colored diamonds. In this guide, we cover the best lab-grown diamond tennis bracelets, how much they cost, and where to shop. 

The price for a lab grown tennis bracelet can vary from $1,200 for a 1 CTW to as high as $10,000 for a 10 CTW bracelet. Prices vary based on factors like total carat weight, the kind of precious metal used, and the design style.

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.

What is a lab-grown diamond tennis bracelet?

Lab-grown diamond tennis bracelets are thin bracelets with a symmetrical pattern of lab-grown diamonds forming a complete circle. They’re typically made of gold, platinum, or sterling silver. Lab-created diamonds are made in a laboratory, but share the same chemical, optical, and physical properties as mined diamonds.

Why is it called a tennis bracelet? During the 1987 US Open, tennis champion Chris Evert lost her eternity bracelet on the court. In media interviews, Chris referred to it as her “tennis bracelet,” and the name stuck.

How much does a lab-grown diamond tennis bracelet cost?

The average cost of a 1 carat lab-grown diamond tennis bracelet is $1,200. Lab-grown diamond tennis bracelets range from $700 to $17,000 depending on the total carat weight, type of precious metal, and style. 

The cost of a 10-carat lab-grown tennis bracelet falls between $5,000 and $17,000 depending on the quality of the stones and the precious metal.

In general, lab-grown diamonds cost 30-50% less per carat than mined diamonds of the same quality.

How to choose the perfect lab-grown diamond tennis bracelet

Finding the best lab-grown diamond tennis bracelet means keeping an eye on a few important details, such as diamond quality and metal. 

Lab Diamond Tennis Bracelet Cut, Clarity, and Color

The quality of the diamonds, including their cut, color, and clarity, impact how brilliant and eye-catching your tennis bracelet is. In general, aim for a minimum color of H or better for diamond tennis bracelets and clarity of SI1 or better. 

Keep in mind that for bracelets with a total carat weight of 5 or less, the 4Cs of diamonds don’t matter as much as they do for an engagement ring. The stones are simply too small to notice imperfections. 

Lab Diamond Carat Weight

Lab-grown diamond tennis bracelets range from 1 carat to 15-carat total weight (or more). Determine what’s in your budget, but also compare what style you like the best. You may not want a thick tennis bracelet, but instead one with a more delicate appearance and smaller stones. Bigger isn’t always better.

Lab Diamond Shape

Diamond tennis bracelets can feature round diamonds for a classic look or other shapes such as princess cut and oval cut diamonds. Look at a range of shapes on tennis bracelets to see what appeals to you the most. 

Diamond shapes

Precious Metal

14K and 18K gold have more durability and longevity than sterling silver while being more affordable than platinum. You can choose between rose gold, yellow gold, and white gold. If you want a contrasted look, opt for yellow gold or rose gold. For a more understated but classic appearance, white gold is the way to go. 

Comfortable Fit

You want your bracelet to fit you securely but not be uncomfortable. You don’t want it too tight or to feel like it’s going to roll off your wrist. Measure your wrist before ordering your bracelet so you don’t have to worry about sending it back for a different size. Find more details in our tennis bracelet size guide below

Diamond Certifications

Diamond certifications matter when you’re buying a center stone for an engagement ring or a large diamond pendant. But for tennis bracelets, with 30 or more diamonds, the cost of getting certifications for each stone isn’t worth it (or necessary).

Vetted Vendor

You want a diamond bracelet that is well-made and holds up for years to come. Be sure you shop with a reputable vendor such as Blue Nile or James Allen. These vendors offer well-crafted jewelry at competitive prices. They’re also known for their excellent customer service and return policies. 


Put together an idea of what you’d like to spend on a tennis bracelet then compare prices at various vendors. Look at different carat weights and styles to see what fits your budget. Be sure to focus on the quality of the bracelet and diamonds overcarat weight. A stunning, well-made bracelet with a 3-carat total carat weight is far more beautiful and eye-catching than a faulty, cheaply-made 5-carat bracelet.

Moissanite vs. lab diamond tennis bracelets

Moissanite is a colorless gemstone composed of silicon carbide and is distinct from a lab-created diamond. It doesn’t have nearly the same brilliance as lab-grown or mined diamonds. They are duller than diamonds and give off a more rainbow-sparkly light. A lot of moissanite stones tend to resemble a K on the color scale, meaning they have a brown or yellow tint to them. Stick to a lab-created diamond for beautiful brilliance and fire.

Tennis Bracelet Size Guide

Your tennis bracelet should fit securely on your wrist, and not be too tight or too loose. While bracelet sizes don’t matter as much as ring sizes (which should be an exact fit), aim to get as close as you can for both comfort and security.

  1. Measure your wrist with a piece of yarn or ribbon.
  1. Cut the ribbon or yarn to the length of your wrist’s circumference.
  1. Measure the cut piece of yarn or ribbon with a ruler or tape measure.
  1. Add a half inch or one inch to your measurement to calculate your bracelet size. If your wrist measures six inches, consider a 6.5 to 7-inch bracelet depending on how loose you’d like the fit.

The most popular bracelet sizes for women are 7 and 7.5, so consider these as a starting point if you’re unsure.
