Make a statement with our lab-grown diamond tennis necklaces, designed for those who love sustainable luxury. Each necklace features brilliant lab-grown diamonds set in recycled gold or platinum, blending timeless elegance with ethical craftsmanship.
A tennis necklace is a continuous line of diamonds or gemstones that wraps all the way around your neck, from clasp to clasp, creating a clean, symmetrical band of sparkle. A lab grown diamond tennis necklace uses lab created diamonds instead of mined stones, giving you the same brilliance, clarity, and durability—paired with a more modern and transparent origin.
In MiaDonna’s collection, each lab grown diamond tennis necklace is designed to sit comfortably along the neckline while showcasing a beautifully matched row of diamonds. Lab grown diamonds share the same chemical and physical properties as mined diamonds, so you’re still choosing a true diamond tennis necklace—with a style that reflects today’s most popular choice for those who care about ethical practices, social responsibility, and attainable luxury.
Our lab grown diamond tennis necklaces come in a range of styles, lengths, and total carat weights—so you can find the perfect look for everyday wear or special occasions. Choose from Riviera styles (diamonds grow larger toward the center for a spotlight effect), double-row designs (extra sparkle and presence), lariat styles (a dramatic drop that elongates the neckline), and graduated looks (a smooth, balanced transition in diamond size).
Popular lengths include 16" for layering, 18" for most necklines, and longer options for added drama. Available in 14k white, yellow, or rose gold, and platinum to match your engagement ring, wedding set, or everyday favorites.
Choosing the right lab grown diamond tennis necklace comes down to how you’ll wear it and what feels most true to your personal style.
Because lab grown tennis necklaces are often more price‑accessible than similar mined diamond styles, you can usually choose the carat weight, length, and metal you truly love without compromising on quality. Whether you’re drawn to a subtle, everyday line of sparkle or a show‑stopping strand of lab grown diamonds, a lab grown diamond tennis necklace is a timeless way to express your style.
