This oval lab grown diamond tennis necklace brings together graceful proportions and continuous sparkle in a design that sits beautifully along the neckline. Oval diamonds create a soft elongated silhouette, while clusters of round brilliant diamonds between each station add extra brilliance without overwhelming the clean line of the necklace.
Seventeen oval lab grown diamonds are carefully spaced with sixty-four round accent diamonds to create a refined rhythm of sparkle. The four-prong baskets allow light to enter from every angle, while the secure box clasp keeps the necklace comfortably in place throughout the day and into the evening.
Made to order in your choice of eleven precious metal options and four popular necklace lengths, this piece transitions effortlessly from everyday luxury to special occasions.
Design Highlights
Spotlight
Rather than using a single uninterrupted row of diamonds, this design alternates oval center stones with sparkling round diamond clusters. The result is a necklace with beautiful movement, extra dimension and an elegant vintage-inspired rhythm while remaining unmistakably modern.
Oval diamonds combine brilliant-cut sparkle with an elongated outline that flatters the neckline while appearing larger than many other shapes of the same weight. The surrounding round brilliant diamonds enhance every oval with additional flashes of light.
Every Signora Jewels diamond is lab grown—chemically, physically and optically identical to a mined diamond. They are graded using the same 4Cs, offer exceptional brilliance and durability, and provide outstanding value with a fully documented origin and no mining footprint.
Available in Sterling Silver, 10K, 14K and 18K Yellow, White or Rose Gold, as well as Platinum. Choose the length that best suits your style: 16 inches sits close to the collarbone, 18 inches is the everyday favorite, while 20 and 22 inches create a longer statement look.
Clean using warm water, mild soap and a soft brush. Store separately to protect the finish and remove before swimming or applying perfumes and lotions.
Is this an adjustable necklace?
Yes. You can choose from four popular finished lengths—16, 18, 20 or 22 inches. The diamond count and price increase with longer lengths to maintain the continuous design.
What makes this necklace different from a traditional tennis necklace?
Instead of using identical stones throughout, this design combines oval lab grown diamonds with sparkling round accent clusters, creating more texture, movement and visual interest while maintaining the classic tennis silhouette.
Are lab grown diamonds real diamonds?
Yes. Lab grown diamonds are chemically, physically and optically identical to mined diamonds. They receive the same grading standards and offer the same brilliance and durability.
What clasp keeps the necklace secure?
The necklace features a box clasp that provides a secure closure while maintaining a clean, elegant appearance.
Which metal options are available?
