red blood cells necklace L | 18k gold vermeil
Red blood cells shed their nucleus to make room for 270 million hemoglobin molecules. A biconcave disc 7-8 micrometers across, made to flow through capillaries thinner than itself. Life depends on a shape that optimizes oxygen delivery with nowhere left to spare.
The Science of the Red Blood Cell
Erythrocytes are among the most specialized cells in the body, lacking a nucleus and all organelles except hemoglobin. The biconcave disc geometry maximizes surface area for oxygen diffusion while maintaining the flexibility to deform through capillaries smaller than the cell itself. Each red blood cell carries 270 million hemoglobin molecules. The lifespan is 120 days, with approximately 2 million cells produced per second in bone marrow via erythropoiesis, driven by erythropoietin from the kidney. When erythrocyte production fails or hemoglobin structure is disrupted (sickle cell disease, thalassaemia), oxygen delivery collapses. Anaemia remains one of the most common pathologies worldwide.

FAQ
Why does the biconcave shape matter?
The concave sides maximize surface area for oxygen diffusion and allow the cell to deform through capillaries smaller than itself. This shape is the result of millions of years of evolution optimizing the single job of carrying oxygen to every tissue in the body.
What makes red blood cells unique?
They lack a nucleus and organelles, dedicating all their interior space to hemoglobin (270 million molecules per cell). This extreme specialization trades long-term survival for peak oxygen-carrying capacity. The cell lifespan is 120 days in exchange for maximum functional efficiency.
What material, size, and chain do I get?
26 mm pendant in 18k gold vermeil (sterling silver core with 2.5 micron gold plating), nickel-free and hypoallergenic. 45 cm gold vermeil chain with lobster clasp and 5 cm extender. High-polish finish. Comes in a ready-to-gift, eco-friendly jewelry box with the 30-day “Love It or Return It” policy. Free worldwide DHL Express shipping (1-5 business days).
How does the gold version compare to silver?
Same 26 mm design, same chain length. The material is the only difference. Gold vermeil warms the reflectivity and gives it a more formal tone. Both versions ship with all duties and taxes covered.
