[The Rarity of the Four-Ridge (Si Leng) Mutation]

In the Wenwan world, finding a true "Si Leng" (Four-Ridge) walnut is an exceptional rarity. While standard walnuts feature two natural seams, and occasional mutations produce three (San Leng), a four-ridge mutation is an extreme natural anomaly. The shell grows with four distinct seams, creating a unique cross-like or square footprint. Because these occur so infrequently in nature, finding two that are similar enough to form a Collection Grade matched pair is a monumental challenge, making this set highly prized among serious collectors.

[About the Jade Seal (Yu Xi) Variety]

The Yu Xi, translating to "Jade Seal" or "Imperial Seal," is a majestic variety revered for its imposing aesthetic. It is characterized by a broad, incredibly flat, and stable base that structurally resembles the heavy stamp used by ancient emperors. This solid foundation provides a deeply satisfying, heavy feel in the hand, while the thick shell ensures a steady and beautiful patina transformation over time.

[Characteristics of YXSL-001]

• Collection Grade Matching: As a top-tier "Shou Cang" (Collection) grade set, these walnuts have been meticulously sorted from an already microscopic pool of four-ridge mutations. They mirror each other exceptionally well in their four-sided symmetry and overall silhouette.
• Commanding Profile: Measuring a substantial 43.0mm in width and squatted to 38.0mm in height, this pair perfectly embodies the Imperial Seal shape. The wide, 4-ridge base sits heavy and stable in the hand.
• Unique Tactile Experience: The four distinct edges fundamentally change the rotational dynamics of the walnuts. Instead of a smooth, rounded roll, the four ridges provide distinct, square-like leverage points for a highly engaging and unique hand exercise.
• Investment Piece: Due to the extreme scarcity of four-ridge formations combined with the highly sought-after Jade Seal shape, this pair is designed for dedicated collectors looking for a true centerpiece for their collection.
