This quote means that each and every one is as special as diamonds.

We are shaped and molded by people we are and the way we change due to the teachings of the life. Just the way pressure is needed to transform a piece of coal into a diamond, we also require pressure for our transformation.

Each and every human is precious and unique. From transformation of coal to diamond we need to go through intense pressure which we have to bear with patience. The result will always be fruitful.
