The song "Love a Diamond" by Tonic seems to explore the idea of love and its various facets. It delves into the complexity and value of love through the metaphor of a diamond.

The lyrics suggest that the narrator is drawn to someone who cherishes and appreciates the beauty and preciousness of a diamond. This person holds the diamond softly in their hand, symbolizing their gentle and delicate approach to love. By keeping it warm and close to their heart, they demonstrate their deep emotional connection to this love, showing that it holds a significant place in their life.

However, there is also a sense of disillusionment present in the song. The repeated lines "Love was overrated, love was hard to find" indicate that the narrator has had past experiences where love did not live up to their expectations. They might have felt let down or struggled to find genuine love in their life.

The phrase "Be it true or be it underhanded" suggests a lack of trust in love, perhaps due to past betrayals or dishonesty experienced by the narrator. Despite this, they are unwilling to harbor negative feelings or allow themselves to be vulnerable, as indicated by the lines "I won't harbor, and she won't crawl." They seem determined not to let past experiences hinder their ability to love and be loved.

Overall, "Love a Diamond" reflects on the value and challenges of love. The song suggests that although love may be elusive and subject to disappointment, it remains a precious and desired experience that holds the potential for deep connection and emotional fulfillment.
