red blood cells ring | sterling silver
The cell you carry in the trillions. A shape that exists for one reason: that biconcave disc packs more oxygen into your blood than any other form. Wear one and carry the structure that keeps every cell in your body alive.
The Science of the Red Blood Cell
There are roughly 25 trillion red blood cells (erythrocytes) in the adult human body. Each biconcave disc lives for approximately 120 days, making roughly 75,000 circuits of the circulatory system before being cleared by splenic macrophages. At any moment, approximately 2 million new cells are produced in bone marrow precursors to replace them. Each cell contains roughly 270 million hemoglobin molecules, the iron-protein complex that binds and carries oxygen. The biconcave geometry increases surface area by roughly 25 percent compared to a sphere, allowing faster oxygen diffusion across the cell membrane.
Who Reaches For This

FAQ
Who wears a red blood cell ring?
Hematologists, blood bank scientists, researchers studying erythropoiesis, medical students, and anyone with a personal connection to blood donation or transfusion medicine. About 20 percent of orders ship to clinicians in hematology, the rest to science enthusiasts and gift-givers.
Why is the biconcave shape functionally important?
The biconcave disc maximizes surface area relative to volume, allowing oxygen diffusion to be fastest at the cell's thinnest point. The shape also allows the cell to flex and deform when passing through capillaries, which rigid spheres could not do. Every feature of the erythrocyte is shaped by the physics of oxygen transport.
What size and material? How do I determine my ring size?
925 polished sterling silver ring, available in US sizes 5-9. Nickel-free and hypoallergenic. To determine your ring size, wrap a strip of paper around the base of your finger (below the knuckle) and mark where it overlaps. Measure the length in millimetres and reference a ring-size conversion chart, or contact us for guidance. All import duties and taxes are covered by Science Jewelry 18:24.
What if the fit isn't right?
All jewelry is covered by a 30-day “Love It or Return It” policy. If the size or fit doesn't work, we will help you find the right option with a free exchange.
