The dancer is a woman with short purple hair, a long sleeve purple turtleneck, a gold cage girdle belt that resembles a diamond, pink tights with large holes, and black stiletto ankle boots. At some points she changes black with most of her outfit changing to white and grey. She has a rainbow outline.
Both dancers are hardly detailed, with only their silhouettes present. P1 is a woman and P2 is a man, both with short hair. P1 appears to be wearing a short sleeve shirt, and P2 appears to be wearing a tank top. At some points, brightly lighted yellow arrows can be seen moving on their shadows. They resemble the Rich Girl Chair dancer in that neither of them have many visible features and the way they are black all over.
The background is black with white rising glitter resembling the titular diamonds. At some points a rainbow circular light and a shining white light in the distance shine about. The light is likely to have been caused by the diamonds' reflections of light. At some point during the chorus the background zooms out with the dancer, revealing more diamond covered floor and as the dancer zooms back in strings of diamonds appear in the background.
The background is completely white with the exception of the two bright blocks - one orange and the other red - used as seats. A spotlight illuminates the walls and dancers at some points of the dance; it zooms in and out at some points.
Diamonds has an unreleased Mashup with the theme Fashionable Men which was discovered in the game files.
Diamonds has a Community Remix.

The Mashup that is not released has 2 Gold Moves, all of which are the same: All Gold Moves: While bending your torso slightly, move your right hand from the left to the right in a circular motion. (Fine China)
However, it is only the second alternate routine to actually have had its gameplay revealed before the game release.
The Seated Dance is the first routine where the dancer(s) has/have ever been close to the screen without the zoom effect being used. The second routine is Teacher (Car Version) and the third routine is What Is Love (Car Version).
The background might've been inspired by the presentation that Rihanna had on to resemble the columns of diamonds coming from the floor.
On justdanceworld.com, there was a video of the Community Remix with the routine that is mildly different to how it should be. It has the lyrics for She Wolf (Falling To Pieces) in the style of the first game (without being colored in or staying in a grey shade before appearance), it has a pictogram from Good Feeling, and the player names have the same font as they did in Just Dance 2014, with all of them being too long for the max letters for names.
