A small square of black onyx in a clean silver frame, hung from a wide, polished bail. Nothing else on it, which is the point: it layers with other chains or works alone as a quiet daily pendant, and it makes an easy gift for someone who rarely wears jewelry.

Necklace length guide
See where each length falls on the body. Most everyday necklaces are 18″ (46 cm): they sit just below the collarbone. Pick longer for V-necks, shorter for high necklines.
Where each length falls
| Length | cm | Style name | Best with |
|---|---|---|---|
| 14″ | 36 | Collar | Off-shoulder, deep V |
| 16″ | 41 | Choker | Boat neck, scoop, off-shoulder |
| 18″ | 46 | Princess | Anything, most versatile |
| 20″ | 51 | Matinee | Crew neck, button-up, V-neck |
| 24″ | 61 | Matinee | V-neck, blouses, business |
| 30″ | 76 | Opera | Sweaters, dresses, layering |
| 34–35″ | 86–89 | Rope / Lariat | High necks, long pendants |
Tips & styling
- Not sure where to start? 18″ (46 cm) is the safest universal length. It suits almost every neckline and frame.
- Match neckline. Higher tops call for longer chains (20″+); open necklines look best with shorter (16–18″).
- Layering. Stack with at least 2″ (5 cm) of difference (e.g. 16″ + 18″ + 20″), so each piece sits clearly.
- Heavy pendants drop. A bold pendant on a fine chain effectively shortens the look by ~0.5″ (1–2 cm). If between sizes, size up.
- Frame. Petite frames flatter shorter chains (16–18″). Taller frames carry longer (20–24″) beautifully. Plus-size frames often look elongated by 20″+.
- How to measure your own chain. Lay it flat and measure from end to end including the clasp. That's the standard length quoted on the product page.
