Measure a necklace you already own

Lay the necklace flat and straight on a level surface. Measure it from one end to the other, including the clasp.

Or measure on your body

Use a flexible measuring tape or piece of string and position it around your neck where you would like the necklace to sit. Mark the meeting point, then measure the length against a ruler if using string.

The Nautilus Pendant draws its form from the chambered curves of a sea shell, reshaped into a translucent azure sculpture with softly carved ridges. A clustered sparkling stone center and delicate pavé accents bring a precise flash of brilliance to its organic silhouette.

Inspired by the sea, it carries a sense of freedom and individuality — the confidence to follow your own rhythm. Its sculptural form feels artistic, while the refined stonework keeps it polished and easy to wear from everyday dressing and workwear to dinners and weekends.

Part of our marine-inspired family, the Nautilus Pendant pairs naturally with other H&Aquarius pieces or your existing favorites, whether worn as a focal point or layered into a more personal look.

  • Rhodium-plated sterling silver
  • Cubic zirconia
  • High polish
  • Cable chain
  • Lobster clasp
  • 17.7 in total · 2.1 in adjustable extender
  • 20.4mm × 13.8mm
  • Silver weight: Approx. 3 g

To help preserve the rhodium-plated finish and brilliance of the stones, keep your jewelry away from prolonged moisture, perfume, lotions and household chemicals. Gently wipe with a soft, dry, non-abrasive cloth after wear and store separately in a cool, dry place. Stone settings are best protected from strong impact and pressure; if a stone ever feels loose, we recommend pausing wear until the setting can be checked. Abrasive polishing products are best avoided, as repeated polishing may gradually affect the plated surface.

    The Nautilus Shell Pendant Necklace looks more dimensional in person than it did in the flat product photos. The pendant has enough presence to be noticeable without taking over the whole neckline.

    The 20.4mm × 13.8mm pendant size was a little easier to understand once I saw it on. The close-up photos made it feel larger, while the real scale is more wearable day to day.

    The 17.7 in total · 2.1 in adjustable extender length works well with both crew necks and open collars. I like having some room to adjust where the pendant sits.

    Weight-wise, the listed silver weight: approx. 3 g gives the necklace a more finished feel. It stays centered better than some of my ultra-light necklaces.

    The silver tone is softer in daylight than it looked on my screen. Indoors it reads a little warmer, so the color changes subtly depending on the light.
