Video insights

@bit_wonder's TikTok video "Pearls Aren't Made of Sand 🎧 Is a pearl made from a grain of sand? Rarely: a natural pearl often starts with a tiny parasite or a wound, and the oyster seals it in and coats it in nacre. Inside a pearl oyster, the intruder is walled off in a sac of the oyster's own cells, which lay down nacre layer by layer: flat aragonite crystal bricks about half a micrometer thick, glued with protein, 2,000 or more layers per millimeter. Each layer is about as thick as a wave of light, so the layers sort moonlight into a rainbow shimmer. The same nacre lines the inside of the shell: mother-of-pearl. Pearl farms start one on purpose with a shell bead and a scrap of mantle tissue.
