Table Coral Sample (Subnautica)

The Gemmed Disk Piece (Opal Gem) is a raw material that can be harvested from Gemmed Disks.

They cannot be harvested by hand. The player has to use their knife in order to cut the Gemmed Disks, causing the Disk to break and drop several Gemmed Disk Pieces.

At the moment, there is no distinction between Gemmed Disk Pieces obtained from Green, Purple, Blue or Red Gemmed Disks. They all will show up as a brown Gemmed Disk Piece in the inventory.

Gemmed Disk Pieces are currently displayed as "Opal Gem" in the fabricator menu.
