The Black Hearts Tennis Necklace pairs seven black heart accents with cubic zirconia outlines on a polished silver-plated chain — a refined, statement-ready piece for everyday or evening.
Reference where each chain length sits on most people. Between sizes? Size up — you can always layer a shorter chain on top.
| 16″ | Base of the neck — choker-adjacent. Great solo or layered on top of a longer chain. |
| 18″ | Just below the collarbone — our most popular, everyday length. |
| 20″ | A few inches below the collarbone — perfect for layering underneath or for a longer pendant drop. |
Tip: Stack two lengths together for a layered look — try 16″ + 20″.
Stainless steel with silver plating and cubic zirconia accents. Avoid water, perfume, and lotion. Wipe gently and store dry.
