Changhua Bloodstone
Changhua bloodstone, known as chicken blood stone for its vivid red inclusions, represents one of China's most visually distinctive seal stones. The contrast between dark base material and bright red cinnabar patches creates dramatic effects.
Material and Formation
The stone consists of dickite or pyrophyllite matrix with cinnabar inclusions creating red patterns. The red blood should be vivid, even, and well-distributed for highest value.
