[About the "Nanjiang Stone" Variety]

The Nan Jiang Shi, translating to "Nanjiang Stone," holds absolute legendary status as one of the traditional "Four Famous Walnuts" in the Wenwan world. It earns its name from its defining characteristic: an incredibly dense, bone-hard shell that feels literally like solid stone in the hand. Visually, it is recognized by its rugged, deeply pitted texture and its signature "cross-shaped" tip. Because the shell is so dense, the Nanjiang Stone is notoriously the slowest variety to color. It is considered the ultimate test of a collector's patience. However, those who dedicate themselves to the journey are rewarded with the most spectacular, glass-like, translucent agate finish achievable in the hobby.

[Characteristics of NJS-903]

• Commanding Ergonomic Geometry: Measuring a massive 40.0mm in width but a slightly shallower 38.0mm in depth. Reaching the 40mm threshold places this pair firmly in the highly coveted giant category, offering a dominant visual footprint. However, the 38mm depth creates a beautifully streamlined, slightly flattened posture. This specific geometric ratio ensures the massive shells sit comfortably close to the hand, making them incredibly effortless to manipulate without overstretching your fingers.
• Bone-Hard "Stone" Texture: The surface displays the signature deep, rugged, and cavernous pitting of the variety. Combined with its extreme density, this aggressive topography acts as intense natural traction, delivering profound deep-tissue acupressure massage that rings with a distinct, crisp sound when the shells gently tap together.
• Classic Signature Profile: This pair perfectly captures the essence of the Nanjiang Stone, featuring a rugged, broad-shouldered stance, a flat and stable base, and the iconic cross-shaped tips.
• Expert Aging Tip: Because the Nanjiang Stone is incredibly dense and famously slow to color, early maintenance is critical. We strictly recommend resting them in a sealed bag between handling sessions for the first month. This expert technique traps natural hand oils and safely accelerates even oxidation, preventing the dense shell from drying out and yielding far better results than using gloves.
