Blurite rock is a rock that, when mined, gives blurite ore, which can be used in the making of the hilt of the blurite sword in The Knight's Sword quest and in crossbows and bolts. It can be mined by a player with level 10 Mining. Blurite rocks can only be found in the Asgarnian Ice Dungeon mine in the Asgarnian Ice Dungeon, located south of Port Sarim on the tip of the Asgarnian Peninsula.

Low-level players should take caution before entering the caves due to the presence of Ice warriors and Ice giants. However, there is a safespot. Situated right in front of the blurite ore is a single stalagmite. You can mine one of the rocks from directly behind it and trap all attackers on the other side. To get the other rock, you may run around, mine it, and situate yourself back in the safespot.

Pre-roll

The mining gem drop table has a 1/256 chance to roll on every mining attempt;^[1] if the player is wearing a charged amulet of glory, amulet of glory (t), or amulet of eternal glory, the probability increases to 1/64.2.^[2]^[3] If the table successfully rolls, the player may receive an uncut gem or nothing, and in either case can not receive an ore.^[4] This neither depletes the rock nor grants Mining experience. The rates shown are for every mining attempt.
