Black Gems are a type of gem that first appear in the Gemcraft Chapter 2: Chasing Shadows. The ability of the black gem is bloodbound, which used to be the ability of the red gem in Gemcraft: Labyrinth. The bloodbound effect in GC2 differs from the red gems of GCL. Instead of a percentage of total kills being added to maximum and minimum gem damage, bloodbound now increases damage and non-bound specials by a multiplier that increases determined by the hit level of the gem's total hits. The tome that unlocks the black gem skill is found on field W5.
Black Gems
Bloodbound gems are available as starting gems on the fields G2, H1, H5, N6, O1, O4, O5, P2, R3, R4, X1, X5, Y6 and perhaps also on hextiles C, L or W.

Tips and Tricks[]
Black gems are an easy way in order to aim for the Super Gem, Hyper Gem or Wicked Gem (300, 600 or 900 max damage on a Level 3 gem) achievement, as they grow stronger in time.
Enchanting gems with Beam can dramatically increase the number of hits of the gem. This can help upgrade the hit level of Black gems.
Trivia[]
- A Grade 12 Black gem can resemble the Gem of Eternity, except they have different abilities and the Gem of Eternity is more powerful than a Bloodbound gem.
