Buy OSRS Diamond necklace
The Diamond necklace is a piece of jewellery in Old School RuneScape. It is made by using a gold bar, a diamond, and a necklace mould on a furnace. Making one needs level 56 Crafting and gives 90 Crafting experience.
The main reason players want this necklace is to enchant it. With the Lvl-4 Enchant spell, it turns into a phoenix necklace. This spell needs level 57 Magic, one cosmic rune, and ten earth runes. That makes the Diamond necklace a smart pick for training Magic or Crafting, or for making phoenix necklaces to use or sell.
You can wear the Diamond necklace, but it has no combat bonuses or penalties. It is very light and weighs only 0.01 kg. It is also available to free-to-play players, so anyone in the game can use it.
The Diamond necklace trades on the Grand Exchange with a buy limit of 18,000 every 4 hours. Its item ID is 1662. The item was released on 8 May 2001. Its look was updated in 2007, and its inventory sprite was rotated in 2018 to set it apart from enchanted jewellery.
