At 9.8 carats with a bold 2.75mm profile, this 14-inch lab grown diamond tennis necklace sits high along the collarbone, creating a sharp, defined line that doesn’t fade into the look. The larger diamonds give the piece a stronger visual weight, while the 3-prong setting keeps each stone open so light moves across the surface instead of sitting still. This is a lab grown diamond tennis necklace that feels immediate the second it’s worn.

How It Wears

At 14 inches, this sits close and structured, framing the neckline with precision. The 2.75mm diamonds create a fuller, more dominant line, making the necklace immediately noticeable without needing additional layers.
The 3-prong setting allows light to pass through each diamond, creating subtle variations in reflection. Instead of a flat shine, the necklace produces a more dynamic, shifting sparkle that feels elevated in motion.

When You Will Reach For It

When you want something bold but controlled.
A last minute gift that still feels substantial and intentional.
A birthday anniversary where impact matters without delay.
An event this weekend where a strong neckline completes the look instantly.
It wears clean as a standalone statement or pairs easily with longer chains for contrast. From day to evening, it holds its presence without adjustment.

Construction Details

Flexible construction allows natural movement along the neckline.
Secured with a box clasp and safety lock for dependable wear.
Natural diamond light variation ensures a more refined, non-uniform shine.
