Onyx is a rare volcanic gem with a shiny black lustre which is used in the Crafting skill to make jewellery. As there are only a limited number of ways to obtain an onyx gem, it is the second-rarest gem in RuneScape behind the hydrix, which requires an onyx to complete.
An uncut onyx requires level 72 Crafting to cut, granting 167.5 Crafting experience when cut. Players may also use the Fletching skill to cut an onyx into onyx bolt tips by using a chisel on a cut onyx at level 73 Fletching. Cutting an onyx into bolt tips grants the player 9 experience in the Fletching skill and gives the player 24 onyx bolt tips. There are other, far cheaper and simpler ways to obtain onyx bolt tips, therefore this practice is not recommended due to the value of the gem.
A cut onyx can be combined with an incomplete hydrix from the Soul Reaper activity to make an uncut hydrix, which is required for hydrix jewellery. Enchanted hydrix jewellery may also be repaired with a cut onyx, recharging the jewellery by 50% and consuming the cut onyx in the process.
Uncut onyx can be purchased from TzHaar-Hur-Lek's Ore and Gem Store in TzHaar City, as a reward from the Fight Kiln, mining ores while using a gem-finding scrimshaw, in an oyster in a player-owned house aquarium, or while mining gem rocks in the Trahaearn District of Prifddinas. 100 onyx dust can also be transmuted to form an uncut onyx.
Onyx can be forged in a furnace with a gold bar and the appropriate mould to produce the following jewellery, which can then be enchanted to perform specific uses.
