Archaeological expert

The Archaological expert is a non-player character at the Digsite who is interested in the historical value of items which might be found there. Players can use items on him and he will tell them if there is any archaeological significance to the item. Players who bring him 3 gold nuggets will also receive 1 gold ore in return. If you also happen to find a clean ruby necklace in the Varrock Museum, you can take it to him to find out how to enchant them.
