Black Gua Sha Stone

1. Unique energetic properties

• Revered as a “detox stone” and “protective shield,” its strong adsorption capacity clears negative energies from the skin and energy field—aligning with Western crystal therapy concepts of “energetic cleansing.”
• The black crystalline structure is believed to form a protective energy barrier, appealing to consumers seeking stress relief in high-pressure lifestyles.

2. Functional physical characteristics

• Natural cooling effect: Volcanic glass conductivity provides instant skin temperature reduction (tested to lower surface temp by 2-3℃), calming redness and inflammation.
• Extreme hardness: 5.5-6 on the Mohs scale (more durable than common jade), maintaining smoothness for precise contouring (e.g., jawline lifting).

3. Aesthetic & cultural fusion

• Deep luster: Our 20-year proprietary polishing technique achieves a mirror finish, with natural “rainbow eye” patterns in premium obsidian creating a unique visual identity.
• Cultural symbolism: Used in Aztec and Native American rituals, its “protective energy” narrative resonates with Western New Age wellness trends.
