Pure Black Obsidian / 纯黑曜石 (Grounding, Protection & Obstacle Clearing) Pure black obsidian is one of the most direct and effective protective stones in feng shui practice. Formed from rapidly cooled volcanic lava, it carries the energy of transformation and decisive change — it is believed to dissolve energetic blockages, absorb negative influences before they can settle, and create a clear, grounded field around the wearer from which forward movement becomes possible. Unlike some protective stones that simply deflect, obsidian also works to clear what is already accumulated, making it particularly useful during transitions or challenging periods.

Blue Chalcedony / 蓝玉髓 (Peace, Communication & Receptive Fortune) Translucent blue chalcedony is one of the more understated and quietly powerful stones in feng shui. Its soft, sky-like blue connects to the energy of the Water element — flow, depth, receptivity, and the capacity to move around obstacles rather than meeting them directly with force. Wearing blue chalcedony is associated with clear communication, peaceful resolution of conflict, and the ability to attract good fortune through openness and ease rather than effort and strain.
