Pearls are expensive and fairly rare. That’s why cultured pearls came about. A pearl is made by an oyster that has sand creep into its shell. The sand is rough and uncomfortable, so the oyster mixes the sand with secretions that create a smooth ball that can be tolerated. When people discovered the process, sand was then purposefully inserted into as many oysters as possible to force them to create pearls. “Forced pearls” just doesn’t sound all that great so, “cultured” was the name given them.
In a similar way, “honor” is constantly forced.
