Diamond gems are the result of mining diamond ore. They are needed to make Bloodstone weapons, Laser weapons, tools, diamond walls, and teleporters. Despite this, they have a light blue color with a somewhat soft texture. They are used as the handles of bloodstone pickaxes, as diamond bullets used in bloodstone guns, in teleporters and all diamond tools, and are also used to make Laser ammunition. They make very sturdy weapons in the game that cut through enemies faster than standard guns and are almost a necessity if you go to Hell or past 2000 distance.
