Blood Gems are upgrade items in Bloodborne that the player can upgrade their Weapons with at the Workshop. Can drop in Chalice Dungeons, be found in chests or dropped by certain enemies. You can also consume some special items to gain unique Blood Gems.
  • There are several types of Blood Gems, which are further divided into categories determined by the general shape of the Gem. Radial, Triangular, and Waning Blood gems are installed onto right-hand weapons. Circlular gems are installed onto left-hand weapons (Except the Lost Chikage, which has a circular socket). Droplet can be fit into any socket regardless of its shape.
  • Blood Gems' strengths vary greatly. This is represented by its rating of 1-20, although higher rarity blood gems are not guaranteed to be stronger than lower level gems.
  • Blood Gems can be installed to Weapons after their Imprint sockets are unlocked via upgrading. A new socket is unlocked at upgrade levels +1, +3 and +6. (Firearms only have 1 or no socket)
  • Installation of blood gems is not permanent. One can remove blood gems and reinstall new ones at the workshop table at any time without consequence or cost.
  • The only known way to gain Bloodtinge Gemstones as drops are from Bloodsucking Beasts and Labyrinth Ritekeepers from chalice dungeons.
  • Gems that grant bonus elemental damage will change your weapon's damage form from physical to bolt/fire/arcane and become scaled by your Arcane stat (strength and skill scaling will be disabled) when installed, unless the weapon deal multiple damage forms by default, in which case the weapon will retain physical/skill scaling but changes damage form to bolt/fire/arcane.
  • Some blood gems have the "cursed" prefix and reduce the weapon's durability. However, multiple installations of such gems do not stack up in effect. E.g. installing 1 cursed blood gem which decreases weapon durability by say 50 and installing 2 of the same gems will make the weapon equally easy to break.
