Detailed Description

Chicken Blood Stone is technically a rock, not a single mineral, composed of a fine-grained mixture of dickite, kaolinite, and quartz, with varying amounts of cinnabar (mercury sulfide) creating its signature red coloration. It is categorized based on its texture and hardness into four main types: Jelly (Dongdi), Soft (Ruandi), Tough (Gangdi), and Hard (Yingdi), with the Jelly variety being the most translucent and valuable. Steeped in Chinese history and culture, Chicken Blood Stone has been cherished for centuries, particularly since the Ming and Qing dynasties. It was a favored material for creating personal seals for emperors, scholars, and artists, who believed it possessed auspicious powers. The stone's vibrant red is associated with good luck, success, and protection from evil. Major sources include Changhua in Zhejiang province and Balin in Inner Mongolia, with Changhua stones being the most historically famous. When collecting, one should prioritize the quality of the 'blood' (color and distribution), the purity of the 'ground' (base material), the overall craftsmanship, and the stone's provenance.

Identification Methods

Observe the color: The 'blood' color is best when it is fresh, condensed, and thick. The brighter, more concentrated, and three-dimensional the red, the higher the quality.

Check the texture: The base material ('ground') should be clean, fine, and free of impurities, with the 'jelly' ground being the best.

Test the hardness: The hardness of Chicken Blood Stone varies greatly (2-7). You can use a small knife to scratch an inconspicuous area. Genuine soft and jelly types will produce a powder, while imitations (like resin) will produce curled shavings and have a plastic feel.

Examine the blood shape: The shape of the 'blood' is diverse, including flake-like, band-like, and star-like forms. Natural and smooth shapes are preferred.

Weigh it by hand: For the same volume, Chicken Blood Stone is heavier than common imitations (like plastic or resin) and has a noticeable weight in hand.

Market Information

The market for Chicken Blood Stone remains strong, driven by its rarity and cultural significance. High-quality pieces, especially those with vibrant, well-distributed 'blood' and a fine, translucent base, command premium prices at auctions and in private sales. Due to resource depletion at major mines like Changhua, the value of top-grade stones is expected to continue rising. Investors and collectors should be cautious of imitations and focus on acquiring authenticated pieces from reputable sources.
