Jade

Jade is a type of semi-precious gem. It can be either aquired using the Mining skill from the Shilo Village's gem rock or mining a random gem rock during the Tai Bwo Wannai Cleanup minigame, or from panning at the Digsite near the River Salve. Jade can be cut with a chisel by a player with 13 Crafting, although there is a chance that the player will accidentally crush it. Successfully cutting a jade grants to player 20 Crafting experience, but if they crush the gem they will receive only 5 Crafting experience. Jade is not used in the creation of jewellery, but can be cut into jade bolt tips for use in creating jade bolts.

Jade exists in RuneScape Classic, but it is only useful in the Legends Quest, other than players being able to sell it to the general shops for money.
