Diamond bolts (e)

Enchanted diamond bolts are adamantite bolts tipped with diamond then enchanted. They can be enchanted through the spell Enchant Crossbow Bolt (Diamond) by a player with level 57 Magic. 10 diamond bolts can be enchanted at a time. They are members only and untradeable.

Enchanted diamond bolts are enchanted with the Armour Piercing enchantment. This gives the bolts a chance of negating a sizeable portion of your opponent's defence against Ranged attacks.
