How It Wears

• At 22 inches, this sits lower on the chest, creating a long vertical line that feels fluid and intentional. It moves naturally with the body, catching light from different angles throughout the day.
• The 4.00mm diamonds give the necklace a wider, more dominant profile, while the 3-prong setting allows each diamond 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 everything.
• 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 statement or layers easily with shorter necklaces for contrast. From day to evening, it transitions without effort.

• Flexible construction allows natural movement along the neckline.
