Summary
This quote suggests that outward appearances can be deceiving. Just like how a rough diamond may look like an ordinary pebble, people or things may be underestimated or overlooked based on initial impressions. It implies that we should not judge something or someone solely based on their external appearance, as beauty or value may lie beneath the surface. It serves as a reminder to look beyond appearances and give a fair chance to things that may initially seem worthless or unremarkable.
