Uncut hydrix is an uncut gem made by combining an onyx with an incomplete hydrix. It can be cut into a hydrix at 79 Crafting, giving 197.5 experience. That cut hydrix is used to make powerful hydrix jewellery.
- Hydrix and onyx are the only gems to lose alchemy value when cut.
- Initially, an uncut hydrix could be given to Kelhar, who would then allow the player to kill 4,000 gemstone dragons. This was changed with the 10 April 2017 update to an incomplete hydrix.
