Diamond drill bits are perfect for drilling through glass, sea glass, stone, gemstones, ceramic, porcelain and shell. DO NOT use Diamond drill bits on metal or soft wood. Metal and some wood is too soft a material and will cause the diamonds to clog up on your drill bit. Carbide drill bits are an excellent choice for metal and wood.
For fused glass and very hard sea glass, you will want to use the diamond core drills.
Diamond is the hardest material and therefore, anything else can be cut or drilled with it. If you are cutting or drilling through very hard materials such as sapphire then bear in mind you will need alot of patience and perhaps more drill bits than you would if you were lets say drilling through glass or Opal.
