Red blood cells necklace S | sterling silver
A red blood cells necklace for haematologists, lab medicine specialists, and anyone who has counted erythrocytes under a microscope. The biconcave disc geometry that defines the most numerous cell in the human body, in the smaller size, 925 sterling silver, 17 mm.
The Science of the Red Blood Cell
The erythrocyte's biconcave disc is not arbitrary. It is the optimal geometry for a cell whose entire function is gas exchange. The shape gives the cell more surface area than a sphere of equivalent volume, places haemoglobin within a short diffusion distance of the membrane, and allows the deformability needed to squeeze through capillaries narrower than the cell itself. Mature mammalian red cells have no nucleus and no mitochondria, which leaves more room for haemoglobin and removes the metabolic competition for oxygen. A single cell carries roughly 270 million haemoglobin molecules and circulates for about 120 days before being cleared by the spleen. The body produces around two million new red cells every second to replace them.

FAQ
Who is this red blood cells necklace for?
People who work with the cell directly: haematologists, transfusion specialists, biomedical scientists, and the wider laboratory medicine team. It also works for clinicians managing sickle cell disease, thalassaemia, or other haemoglobinopathies, and for anyone whose own diagnosis involved a long acquaintance with red cell counts and morphology.
What is the difference between the S and L versions?
The geometry is the same, the size is not. The S pendant is 17 mm, sized for everyday wear and a quieter look on the chest. The L pendant is larger, more emblematic, and reads more clearly from a distance. People who prefer minimal jewellery or want something that disappears under a collar usually choose the small version. People who want the disc to be unmistakable usually go for the large.
Why is the biconcave shape so efficient?
It increases surface area relative to volume, which is what gas exchange depends on. It also lets the cell deform reversibly, which is what passing through narrow capillaries depends on. A sphere of the same volume would have less surface area and almost no deformability, and the body would have to push harder to move blood. Evolution settled on the disc because it solves both problems with one shape.
What size is the pendant and what does it ship with?
The pendant is 17 mm, sized for daily wear under a collar or open-neck shirt. It comes on a 45 cm sterling silver chain (1.8 mm width, lobster clasp) with a 5 cm extender. Free worldwide DHL Express shipping in 1-5 business days, all import duties covered, in a ready-to-gift jewelry box.
