Watch as a nucleated pearl gets cracked open to reveal its inside. When we break the pearl, we can see a round nucleus (typically made from shell) at the center, surrounded by layers of shiny nacre. Here’s how it works: nucleated pearls are created by implanting a small core into an oyster, which then coats that core with nacre over months or years. The end result is a pearl with a clear central nucleus and glossy outer layers. This matters because it helps us distinguish nucleated pearls (like many saltwater pearls or Edison pearls) from non-nucleated ones, and understand the aquaculture process behind pearl formation. It also makes us reflect on how nature and human assistance collaborate to make these beautiful gems—without the starter nucleus, an oyster might not grow a perfectly round pearl, so this method lets us enjoy more uniform, lovely pearls in jewelry.
