The 'perfect' necklace is made during the quest Family Crest. It is made from a 'perfect' gold bar and a ruby. It is given to Avan along with a 'perfect' ring to complete a part of the Family Crest.
It can be worn, but it has the same appearance as an ordinary ruby necklace and gives no bonuses. It cannot be enchanted into a Digsite pendant.
- The P in 'perfect' necklace is not capitalised because all items in Old School RuneScape use ucfirst capitalisation, wherein the first letter of a string is capitalised, but the rest is not.
