[About the "Spherical Nanjiangstone" Variety]

Nanjiangstone (Nan Jiang Shi) is historically celebrated as the most dense, heavy, and stone-like variety within the entire Lion Head (Shi Zi Tou) family. While classic Nanjiangstone usually features anic high-dome shape, the "Spherical" (Qiu Xing) sub-strain is a highly elusive anomaly. It is selected from wild heritage lines where the width and vertical height achieve a perfect 1:1 balance, creating an remarkably smooth, rounded orb shape.

Structurally, this strain combines the extreme rind thickness and iron-like bone density of Nanjiangstone with the effortless, friction-free rotation of a sphere. Lacking any sharp points, it delivers a deeply satisfying, uniform hand massage that targets reflexology points across the palm with supreme physical feedback.

[Characteristics of NJS-1013]

• Flawless 40mm Perfect Orb Proportions: Measuring a precise 40.0mm by 40.0mm, this pair has achieved the ultimate symmetrical geometry. The perfect sphere ratio rests completely naturally in the palm, offering a balanced weight distribution. This ensures that during rotation, the heavy shells roll around each other with continuous, frictionless speed, maximizing focus and muscle relaxation.
• Tight, Cross-Linked Knurled Topography: The surface features the iconic Nanjiangstone texturing—a deeply cut, interwoven network of fine waves and heavy structural channels. This crystalline organic matrix acts as an expert-tier hand massager, stimulating micro-circulation and relieving fatigue after long hours of writing or device usage.
• Iron-Like Bone Density & Crystalline Resonance: True to its wild ancestry, this pair possesses exceptionally thick timber walls and a dense inner core, carrying an immense stone-like weight. When rotated, the shells strike each other to produce a beautifully sharp, high-frequency resonance that confirms the pristine quality of the old-growth wood.

[Expert Aging & Patina Tip]

Nanjiangstone is famous for its dense, non-porous structure, meaning it takes longer to color but rewards the collector with the most breathtaking finish. To ensure your natural skin oils oxidize uniformly across this round pair, keep them inside a sealed pouch when not in use for the first 4 weeks. Rolling them directly with bare, clean hands—completely avoiding gloves—will safely bring out a glassy, translucent deep crimson-jade patina.
