14K Gold 7.17ctw 2.50mm Round Lab Diamond 14 Inches 3 Prong Tennis Necklace

A tighter fit with a noticeably stronger diamond line.
At 7.17 carats and a bold 2.50mm profile, this 14-inch lab grown diamond tennis necklace sits close along the collarbone with a sharper, more defined presence than slimmer styles. The larger diamonds create a more visible line of light, while the 3-prong setting keeps each stone open so reflections move naturally across the surface. This is a lab grown diamond tennis necklace that feels immediate the moment it’s on—no layering required.

How It Wears

• At 14 inches, this sits high and structured, framing the neckline with precision. The 2.50mm diamonds give the necklace a stronger, more pronounced presence, making the line of light more visible without needing additional pieces.
• The 3-prong setting allows light to pass through each diamond, creating slight 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 still 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.
