14K Gold 20.33ctw 2.50mm Round Lab Diamond 30 Inches 3 Prong Tennis Necklace

At 30 inches and 20.33 carats, this lab grown diamond tennis necklace creates a deep, uninterrupted drop that defines the entire look the moment it’s on. The 2.50mm diamonds give the necklace a bold, clearly visible structure, forming a continuous line that carries weight without feeling heavy. The 3-prong setting keeps each diamond open to light, so reflections shift naturally with movement instead of appearing flat. This is a lab grown diamond tennis necklace designed to stand alone—no layering required.

How It Wears

• At 30 inches, this sits low across the chest, creating a long vertical line that immediately draws attention. It moves freely with the body, increasing how often it catches light throughout the day.
• The 2.50mm diamonds give the necklace a fuller, more defined profile, while the 3-prong setting allows each stone to reflect light slightly differently. This creates depth and variation instead of a uniform shine.

When You Will Reach For It

• When you want one piece to define the entire look.
• A last minute gift that still feels substantial and intentional.
• A birthday anniversary where timing and impact both matter.
• An event this weekend where a longer silhouette completes everything instantly.
• It works as a standalone long statement or layers easily with shorter necklaces for contrast. From day to evening, it transitions without effort.
