Red blood cells necklace S | sterling silver
The biconcave disc — minimal, precise, and instantly recognisable to anyone who has looked through a microscope.
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 provides 20-30% more surface area than a sphere of equivalent volume, maximises haemoglobin exposure at the membrane, and enables the deformability needed to navigate narrow capillaries. Without a nucleus or mitochondria, the mature red blood cell is essentially a haemoglobin-filled membrane — simple in design, precise in function.

FAQ
Q: What is the chain length and material?
A: 45cm (18 inches), sterling silver. The red blood cell pendant hangs clearly visible, proportioned for everyday wear.
Q: Would someone outside medicine recognise this?
A: The biconcave shape is distinctive, but most people outside biology won't immediately identify it. That's often the appeal for those who do know.
Q: Why is the biconcave shape so efficient?
A: It increases surface area by roughly 25% compared to a sphere of the same volume, which optimises oxygen diffusion. Evolution chose this geometry for a reason.
Q: Is sterling silver durable for a pendant?
A: Very. It's strong, develops character with wear, and can be polished if you want high shine again. We ship worldwide with DHL Express tracking.
