Red blood cells necklace L | sterling silver

The biconcave disc that carries oxygen to every cell in the body — one of the most recognisable shapes in all of biology.

The Science of the Red Blood Cell

Red blood cells (erythrocytes) are highly specialised cells that have shed their nucleus and most organelles to maximise haemoglobin content. Their biconcave disc shape — roughly 7-8 µm in diameter — maximises surface area for gas exchange while allowing the flexibility to squeeze through capillaries narrower than the cell itself. A single erythrocyte carries approximately 270 million haemoglobin molecules, each capable of binding four oxygen molecules. The average lifespan is 120 days, after which aged cells are recognised and cleared by splenic macrophages.

A Meaningful Gift for Science Lovers

A piece for anyone in medicine, haematology, or anyone who simply loves the elegance of the cell's design.

  • For the haematologist, clinical scientist, or blood researcher
  • For a medical student or nurse as a symbol of their field
  • For anyone who has donated blood or relies on transfusion medicine
  • As a distinctive piece for anyone who appreciates cellular geometry

Comes in a gift box. Free worldwide shipping.

FAQ

Q: What is the chain length?

A: 45cm (18 inches), sterling silver. Long enough to layer or wear as a standard pendant. The red blood cell sits at a recognisable size.

Q: Is this a gift-appropriate piece?

A: Yes, especially for someone in medicine, biology, or anyone drawn to beautiful functional design. It's specific without being obvious.

Q: Why does the shape matter so much?

A: The biconcave disc increases surface area by roughly 25% compared to a sphere, which is why evolution chose it. Form follows oxygen transport.

Q: How is the pendant attached to the chain?

A: Hand-finished sterling silver bail and jump ring, all included. The attachment is as solid as the pendant itself.
