Lab Grown Diamond Necklaces

A lab diamond necklace is a piece of fine jewelry that uses diamonds grown in a lab instead of mined from the earth. The diamonds are real—made of carbon with the same hardness and optical properties as natural diamonds—and are set into pendants, bars, drops, or station designs on gold or platinum chains.

Yes. Lab-grown diamonds are considered real diamonds. They share the same chemical composition (pure carbon), crystal structure, and durability as mined diamonds; they simply form in a lab rather than underground. They are not simulants like cubic zirconia or moissanite.

Both lab and natural diamonds offer lasting sparkle and strength. The key differences are origin and price. A lab-grown diamond necklace often allows you to choose a larger or higher-quality stone within the same budget, making it appealing if you’re value-focused or prefer a more modern production story. If you want earth-mined stones, you’ll find those in Barkev’s natural diamond necklace collection; if you like the idea of more carat for your spend, lab diamonds are a strong option.

In this collection, you’ll see a range of lab diamond necklace styles, including:

• Minimal lab diamond pendant necklaces with bezel or prong settings
  
• Floating and station lab diamond necklaces with multiple stones along the chain
  
• Lab diamond cross and heart necklaces
  
• Pear-shape and drop lab diamond necklaces with graduating stones
  
• Sculptural and intertwined designs that echo Barkev’s natural diamond line, reimagined with lab-grown diamonds
  

Our lab-created diamond necklaces are set in solid 14k and 18k gold (white, yellow, and rose) and select styles in platinum. Chains are typically 16–18 inches and adjustable, so you can fine-tune where the pendant sits and easily layer it with other necklaces.

Yes. Lab diamonds share the same hardness as mined diamonds (10 on the Mohs scale), so a lab-grown diamond necklace is well suited for regular wear. A bezel-set lab diamond pendant or dainty station necklace is a great everyday choice—low profile, comfortable, and bright. Just avoid harsh chemicals, heavy impact, and snag-prone situations, as you would with any fine jewelry.

Absolutely. A lab diamond necklace offers high-impact sparkle and fine metals at an approachable price point, which makes it a strong option for birthdays, anniversaries, and self-gifting. Heart necklaces, cross pendants, and classic solitaire lab diamond pendants are especially easy to wear and don’t require guessing a ring size.
