Blood gems are a special item that can be imprinted on an upgraded weapon, in order to boost its damage, its scaling or its effects further.
Blood Gems can be swapped at any time and promote experimentation of different Blood Gem setups in a players' arsenal in order to figure out what works best in their particular playstyles.
Blood gems exist in five different shapes: Radial, Triangle, Waning, Circle, and Droplet. Each shape offers a different type of enhancement or buff, which is then imprinted on a weapon's corresponding Imprints.
Imprints are blood gem slots found in most weapons. There are four types of Imprints, directly related to the blood gem shape that will fit in it: Radial, Triangle, Waning, and Circle. Note that Droplet shaped blood gems will fit in any type of Imprint slot.
- Radial gems are doubtlessly the most important shape that players can acquire, this stems from the fact all Trick Weapons have two radial slots in every regular variant of any given weapon, which makes radial imprints two thirds of all existing imprints.
- Because of this, the best kind of Radials will be the ones that boost damage, usually Physical.
- Radial gems appear to crystallize from a core and then branch in multiple straight lines, which themselves branch off once more to form a circle, halfway at a specific distance.
- In Chalice Dungeons of Pthumeru, all bosses will drop Radial Gems.
- As stated by the description, they boost mostly attribute.
- In Chalice Dungeons of Isz, all bosses will drop Triangle Gems.
- As stated by the description, they provide fire and bolt damage, as well as healing.
- In Chalice Dungeons of Loran, all bosses will drop Waning Gems.
- Essentially used for firearms, except the "Lost" variants of the Chikage and Simon's Bowblade.
- Similar to Radial gems, but inverted, it is as if the crystal grew as a circle and then branched into the center.
- Gems of this shape are nearly always related to the Bloodtinge stat, which by no mere coincidence, governs the damage and efficiency of Firearms.
- Due to the fact that so many little weapons will ever be able to use them, only the two mentioned above, they make for curious yet useless Out Of Shape gems.
- They will drop from enemies that have a heavy relation with blood, such as Bloodlickers.
- Essentially a category of their own, they will fit in every imprint slot.
- Their appearance resembles that of what can only be described as "viscous crystal".
- Can only drop from Winter Lanterns or from chests that are exclusive to the main game.
- These gems cannot be found in Chalice Dungeons.
- These gems can never drop as out of shape, meaning enemies that would drop any other shape of blood gems cannot drop their usual blood gem in a droplet shape.
Blood Gem Rating determines the rarity and quality of a blood gem, and provides a means of visual comparison between Blood Gems of the same kind.
For every increased Tier, Blood Gems will become increasingly larger, more vivid and with a much deeper color. Abyssal Blood Gems, however, have no tier as they are essentially a tier of its own, and take up a deep black hue, rather than its usual color.
- Blood Gemstones (1) - (3) have a Rating of 1 through 10.
- They are very small and have a bright and faded color.
- Damp Blood Gems (4) - (6) have a Rating of 11 through 19.
- They are larger and more intricate while also appearing to ever increasingly drip with blood.
- Abyssal Blood Gems have a Rating of 20.
- They acquire an extremely dark hue having only a slightly shimmering colored glow to them.
Blood Gemstones (1) 1 - 4 (2) 5 - 7 (3) 8 - 10 Damp Blood Gems (4) 11 - 13 (5) 14 - 16 (6) 17 - 19 Abyssal Blood Gems - 20

Unique Blood Gems
- In general, Pthumeru and Hintertomb Chalice Dungeons provide Radial shapes, Loran Chalice Dungeons provide Waning shapes, and Isz Chalice Dungeons provide Triangular shapes.
- Hp depletion by cursed effect cannot be regained by Rally and can only be healed by Blood Vials.
- Additional Rites will increase the chance of getting better Blood Gems.
- The Rotted offering will make some enemies stronger, and you can notice this by seeing a red aura around them. These buffed mobs will drop better gems.
- Cursed offering halves your hp and makes enemies drop the cursed gems with better stats and random negative effect.

- For every Tier, a Blood Gem will change its icon.
