Diamant means "diamond" in French. It's a beautiful and evocative word that immediately brings to mind images of something precious, rare, and strong.
In the song, Georgio uses it metaphorically to describe himself: "Je me suis cherchée comme un diamant" (I searched for myself like a diamond). This suggests a journey of self-discovery and resilience, implying that he sees himself as something valuable that needed to be found or refined. It's a powerful symbol of self-worth and inner strength.
Georgio looks back on a relationship that was never steady, full of fights, breakups and getting back together, and a jealousy that came from loving too hard.
Years later he finds the old verse again by chance and reflects on how much he has grown since then. He hopes she is doing well, but he is done chasing what hurt him, choosing instead to focus on someone new and on rebuilding himself, piece by piece, like a diamond formed under pressure.
