Diamond: Greatest Hits 2002-2010 is the first official greatest hits album by Filipina singer Nina. It was released in the Philippines on October 13, 2010 by Warner Music, at the time that she has left the label. The tracks are arranged nearly in a chronological order. Disc 1 is primarily a collection of Nina's hits from 2002 to 2004 (with some non-album songs from 2005 to 2007), while Disc 2 is primarily a collection of her hits from 2005 to 2010.

Diamond: Greatest Hits 2002-2010 is considered to be Nina's first ever official greatest hits compilation, since Best of Nina (2009) was exclusively released only in South Korea, and did not have any promotion and participation from the singer. In mid-2010, she left the Warner Music record label and moved to Universal Records. Therefore, she had no contribution and creative input on the production of the album. Also, she was not in control on the contractual agreement of the album. It is clear that she had no participation on the album, since there is no personal message from the singer that can be seen in the album's liner notes. There wasn't even a new song included, just previous releases, and the single "Love Will Lead You Back" was only taken from Nina Sings the Hits of Diane Warren (2008).

The album consists of her commercial singles from her 2002 debut album to her 2009 album, which was taken from her radio show of the same name. It also includes some of her notable songs, all arranged almost in a chronological order. Disc 1 consists of songs from Heaven (2002) and Smile (2003), with some of her non-album releases. Disc 2 includes singles from the box-office Nina Live! (2005) to Renditions of the Soul (2009). The non-singles and non-album tracks are:
