What Are Lab Grown Diamond Necklaces?

Lab grown diamond necklaces feature real diamonds created in controlled laboratory environments using advanced technology. Lab grown diamonds have essentially the same chemical composition, crystal structure and optical properties as mined diamonds, delivering the brilliance and durability expected from diamond fine jewelry.

Choose Your Diamond Shape

Explore necklace designs featuring popular diamond shapes including round, oval, pear, emerald, princess, radiant, heart, marquise and cushion. Round diamonds provide classic brilliance, elongated shapes such as oval and pear create graceful proportions, while emerald and radiant cuts offer distinctive geometric styling.

IGI Certified Lab Grown Diamonds

Unii Jewels uses IGI Certified Lab Grown Diamonds across certified designs. IGI grading reports document important diamond characteristics such as carat weight, color, clarity and cut characteristics, helping shoppers evaluate diamond quality with greater transparency.

Choose Your Necklace Metal

Our lab grown diamond necklaces are available across precious-metal options including 10K gold, 14K gold, 18K gold, platinum and selected silver designs. White gold offers a bright contemporary appearance, yellow gold adds classic warmth, rose gold provides a softer tone, while platinum offers a naturally white precious-metal finish.

How to Choose a Lab Grown Diamond Necklace

• Choose your necklace style: Consider a solitaire or pendant for understated elegance, or a more diamond-intensive design for greater visual impact.
• Consider diamond size: Carat weight influences the overall presence of the diamond or diamonds in the necklace.
• Select your diamond shape: Compare classic round diamonds with oval, pear, emerald and other fancy shapes.
• Choose your metal: Select a precious metal that complements your preferred diamond shape and existing jewelry.
• Think about how you will wear it: Delicate pendants work naturally for everyday styling, while larger diamond necklaces can create a stronger statement for special occasions.
