Where Found
Sapphires are naturally found in the cavernous networks and underground regions of the Blockhead world. They are typically surrounded by hard rock, such as stone. Occasionally, they can be found underwater in a subterranean confined or perched aquifer. Also, when Blockhead is in a meditate, you can gain the sapphire.
Portal Upgrade
Sapphires are needed to upgrade a Blockhead's portal to a sapphire portal, allowing a Blockhead to craft a sapphire pickaxe.
