Buy OSRS Zenyte shard
The Zenyte shard is a rare gem shard in Old School RuneScape. It drops from tortured gorillas and demonic gorillas in the Crash Site Cavern. You can enter this cavern after you finish the Monkey Madness II quest. Tortured gorillas drop the shard at a rate of 1 in 3,000. Demonic gorillas drop it at a much better rate of 1 in 300.
The shard is used to make an uncut zenyte. To do this, fuse the shard with a cut onyx in the wall of flames in the Temple of Marimbo Dungeon. You must hold a zombie monkey greegree while you do it. This gives 15 Crafting experience. The fusion only works there because the flame pits under Ape Atoll are the only heat source strong enough.
Zenyte is the highest level gemstone in the game. It is used to craft some of the strongest jewellery in OSRS. The shard is tradeable and noteable, but it does not stack and cannot be worn. It can be traded on the Grand Exchange with a buy limit of 11,000 every 4 hours.
