Variegated Sundial Shells for Delicate Jewelry & Intricate Crafts

$1.20

These are not seashells; they are miniature timepieces, tiny spirals pulled from the depths of the ocean. The Heliacus Black Sundial is a marvel of miniature engineering, a shell so small and so perfectly formed it seems impossible. Each one is a tiny, dark tower, spiraling to a sharp point, its surface etched with the fine, radiating lines that give it its name—the sundial. The “black” is not a flat color but a deep, mysterious palette, often variegated with rich browns, creamy whites, or subtle flecks, like a tiny, captured nebula. To hold one is to hold a complete, self-contained universe of pattern and precision. They are the secrets of the sea, small enough to be hidden in a closed fist, yet intricate enough to captivate you for a lifetime.

From the Shore

Discovering these shells is an exercise in patience and a reward for the truly observant. You don’t find them with a casual glance; you find them by kneeling down and searching the sands with focused intent. It is a treasure hunt for the miniature world. When you finally spot one, it feels like finding a fallen star or a tiny, ancient coin. You pick it up and hold it in the palm of your hand, marveling at its impossibly small size and its perfect, geometric form. Selecting them is a joy of curation. You search for the most perfect little spires, the ones with the clearest sundial markings and the most beautiful variegated patterns, knowing that each tiny shell is a perfect, tiny masterpiece.

Creative Ideas
The miniature size and intricate beauty of these Heliacus shells make them the ultimate component for fine, detailed craftwork.

  • Delicate, High-End Jewelry: These are perfect for creating elegant, lightweight jewelry. A pair of matching Heliacus shells makes for stunning, unique earrings. A single, perfect shell can be set as a delicate pendant on a fine chain, a tiny secret around the neck.

  • Fairy Gardens & Miniature Worlds: These are the ultimate accessory for creating miniature scenes. They can be seashells on a tiny fairy beach, decorative elements in a dollhouse, or mysterious artifacts in a ship-in-a-bottle diorama.

  • Intricate Mosaics and Inlay Work: Their small size and uniform shape make them ideal for creating detailed patterns and textures in resin art, jewelry inlay, or small-scale mosaic projects. They can add an incredible level of detail and sophistication to any craft.


Each of these shells is a piece of the ocean’s art gallery, sustainably and ethically collected. They are crafted from natural Spotted Marbled Cone snails (Conus ebraeus), celebrated for their unique, dappled patterns and elegant conical form. Please remember that as a natural product, every shell will have its own unique variations in shape, size, and the beautiful patterns on its surface. These are the marks of a treasure, individually painted by the sea.

Every seashell is a gift from the ocean, and I pack each one with the care it deserves, ensuring its safe journey to you.

  • Preparation Time: I will carefully wrap your seashells in recycled paper and twine within 1-3 business days, making it feel like a personal gift from the sea.

  • Shipping Method: I use reliable standard shipping and will provide you with a tracking number, so you can follow your shell’s journey.

  • International Orders: For shells traveling across oceans, please allow a little extra time. Sometimes customs checks can extend their journey.

The ocean never creates two identical shells, making the one you receive truly one-of-a-kind.

  • Damaged in Transit: If your shell is damaged during its journey, please contact me within 24 hours of receipt with a photo. I will immediately send a replacement or issue a full refund.

  • Not as Described: I do my best to represent each shell accurately through photos and descriptions. If you feel your shell is significantly different from what was described, please contact me within 7 days, and we will find a thoughtful solution.

  • A Note on “Change of Mind”: As each shell is a natural, unique item, I cannot accept returns or exchanges due to a “change of mind.” Please review the photos and dimensions carefully to ensure it’s the perfect “ocean companion” for you.

  • Unlike most sea snails that graze on algae, the Heliacus genus has a very specialized and fascinating lifestyle: they are parasites. Most species live on or near sea anemones and corals, feeding on their host’s body tissues while somehow remaining unharmed by their stinging cells.

  • The name “Sundial Shell” comes from the beautiful pattern on its surface. The fine, radial ribs that run from the center to the edge resemble the lines on a traditional sundial, which mark the passage of the hours.

  • These snails are part of the family Epitoniidae, commonly known as “wentletraps,” a name that comes from a Dutch word meaning “spiral staircase.” It’s a perfect description for the beautiful, high-stepped spiral of these tiny shells.
