Onyx

Onyx is a rare volcanic gem with a shiny black lustre which is used in the Crafting skill to make jewellery. There are only 2 ways to obtain an uncut onyx.
 * It can be purchased in the TzHaar crafting store for 2,700,000 Tokkul.
 * It is a rare drop from the Corporeal Beast.

An uncut onyx requires a Crafting level of 67 to cut, granting 167.5 crafting experience. Though it is occasionally worth more uncut than cut, cutting the onyx in hopes of earning money is not advised because of the extremely low demand for onyx gems. It would cost approximately six billion to get 99 Crafting by cutting Onyx.

Members can 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, although this practice is highly unrecommended due to the rarity of the gem and the fact that TzHaar-Ket and TzHaar-Xil both drop Onyx bolt tips rather commonly.

The Personalised shops update on 2 September 2009 raised the price of an Onyx in the TzHaar shops more than tenfold to 2,700,000 Tokkul. On the 15th of December 2009, Jagex made it impossible to get Tokkul by trading runes to the shop. This made it much harder to get Tokkul.

Onyx jewellery looks significantly different from jewellery using other gems.

Trivia

 * When the TzHaar area was first released, the store price for an uncut Onyx was 300,000 Tokkul.
