At 7.5 inches, this 3.12ctw lab grown diamond tennis bracelet brings together extended length and increased diamond size to create a wrist presence that feels complete from end to end. The 2.25mm round diamonds add noticeable density, while the longer length allows that density to spread across the wrist, creating a wider, more continuous field of light.
The bracelet doesn’t sit tight or controlled—it settles into a relaxed drape, allowing it to move naturally with the wrist. The 3 prong setting keeps each diamond open and individually defined, minimizing metal visibility and allowing light to pass through cleanly. As the bracelet shifts, reflections move across the full length in a smooth, uninterrupted flow, creating a continuous visual rhythm rather than isolated flashes.
This is where the bracelet feels both expansive and fluid—designed to be seen in motion as much as at rest.

How It Wears
- The 7.5 inch length creates a fully relaxed drape, allowing the bracelet to move freely across the wrist with a natural, fluid motion. It doesn’t stay fixed—it adjusts continuously, creating a softer and more dynamic wearing experience.
- The 2.25mm diamonds increase visual weight, making the bracelet feel more substantial across the wrist. Combined with the 3 prong setting, each diamond remains clearly visible, allowing light to reflect directly and consistently. As the bracelet moves, reflections flow across the stones in a continuous sequence, creating a rolling light effect rather than static shine.
- It feels fluid in motion, balanced in structure, and strong in presence.
When You Will Reach For It

- A last minute gift that still feels premium and complete.
- A birthday anniversary piece that integrates easily into everyday wear.
- An event this weekend where you want something visible, refined, and effortless.

- From daytime wear to evening settings, it transitions without interruption.
Construction Details
- Each link is engineered for continuous flexibility, allowing the bracelet to follow wrist movement smoothly without stiffness while maintaining structural consistency. It moves freely but does not twist or collapse.
- The box clasp secures with a precise locking mechanism, supported by a safety latch to ensure the bracelet remains firmly in place during wear. The closure is smooth, reliable, and designed for repeated use.
- Natural variation in diamond reflection prevents a flat or overly uniform shine, giving the bracelet a more refined and realistic appearance.
