For the Diamonds present in the storyline of Grand Theft Auto IV and its DLC, see Diamonds.

Diamonds is a jewellery store with branches in East Beach and Jefferson, Los Santos, in Grand Theft Auto: San Andreas.

The business is inaccessible to the player and plays no role in the storyline whatsoever. However, while doing the taxi driver side-mission in Los Santos, passengers may ask to be taken to the store in Jefferson, identified as "Leon Diamonds".
