The meaning of "Diamond" is that we as individuals, often feel pressured by society, family and friends to maintain a certain image. Wanting to mold us into their likening. This song is telling you to break away, and bloom into the person you want to be.
For this music video, I chose figure skating, because it has been a part of my childhood since the age of five. Like all sports, one will feel the pressure from friends and family.
Diamonds form under pressure.
Do it because you want to do it, not for them.
