At 18 inches and 10.46 carats, this lab grown diamond tennis necklace drops just below the neckline, creating a more relaxed flow compared to shorter styles. The 2.50mm diamonds give the piece a stronger, more noticeable structure, forming a continuous line that feels solid without becoming heavy. The 3-prong setting keeps each stone open to light, so reflections shift naturally instead of appearing flat. This is a lab grown diamond tennis necklace that doesn’t need layering to feel complete.

How It Wears

At 18 inches, this sits slightly lower, creating a natural drop that allows the necklace to move with you. The 2.50mm diamonds give the line a fuller, more defined look, making it more visible across the chest.
The 3-prong setting allows light to pass through each diamond, creating subtle differences in reflection. Instead of a uniform shine, the necklace produces a more dynamic, shifting sparkle that feels elevated in motion.

When You Will Reach For It

When you want something noticeable without overthinking it.
A last minute gift that still feels substantial and intentional.
A birthday anniversary where timing matters without compromise.
An event this weekend where a defined neckline completes the look instantly.
It works as a standalone piece for a clean, strong look or layers easily with shorter necklaces for contrast. From day to evening, it transitions without effort.

Construction Details

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