The diamond demon statuette is a demon statuette found in the final room of the Lumbridge Catacombs Dungeon after completing The Blood Pact. It is the sixth and final statuette that can be sold to Xenia for 1,000 coins. The statuette will be protected by a barrier and attempting to take it will make Dragith Nurn attack you. You must defeat it to claim the statuette. Once you have sold it to Xenia, you cannot receive another. This item has no other use.
