Kidney necklace | 18k gold vermeil
The kidney is a filtering engineer that works continuously without complaint. One million nephrons per organ, filtering 180 litres of blood daily while reclaiming 99% as urine, using pressure, osmotic gradients, and active transport in a cascade no artificial system has fully replicated.
The Anatomy of the Kidney
The kidney's structure is pure function. The cortex houses the glomeruli, where blood first enters the filtration process. The medulla contains loops of Henle that create osmotic gradients, enabling the concentration of urine and conservation of water. The collecting duct is the final site of fine-tuning. The renin-angiotensin-aldosterone system links kidney function to blood pressure regulation. Chronic kidney disease is measured by glomerular filtration rate (eGFR), and its progression determines dialysis and transplantation timelines. Polycystic kidney disease, glomerulonephritis, and acute injury are the major clinical threats.

FAQ
Is this something a nephrologist would actually wear?
Yes. The kidney is their specialty and their thought partner. A gold vermeil version signals that this is a milestone piece, worn by someone who has invested deeply in understanding renal physiology and cares enough to carry it daily.
How does the kidney concentrate urine?
Through the countercurrent multiplier system. The loop of Henle creates an osmotic gradient, and the vasa recta preserves it. The collecting duct is where aldosterone acts, allowing fine control of water reabsorption. This is why the kidney can produce urine far more concentrated than blood, an engineering solution that took evolution millions of years to refine.
What size, material, and chain come with this?
21 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 5 cm extender, lobster clasp. Ships free worldwide via DHL Express in 1-5 business days. Comes in a ready-to-gift eco-friendly box with the 30-day “Love It or Return It” policy.
Is there a silver version at the same size?
Yes. Kidney is available in sterling silver at 21 mm. Same design, same filtration physiology, same meaning. Material is the only difference. Many renal specialists pair both versions or gift the silver to lab colleagues.
