Faceted diamond

s are miscellaneous crafting materials, mined from outcroppings found in the dungeon, on levels 8, 11, 13 and 15. These crystal protrusions require a pick axe to be mined, as well as the appropriate technology to be unlocked. Each of these crystals will yield 4x diamonds (or 5x with the Jeweler perk). As of v1.3, the merchant no longer sells or buys this item.
