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.\u003c\/p\u003e\n\u003ch3 data-path-to-node=\"10\"\u003e\u003cb data-path-to-node=\"10\" data-index-in-node=\"0\"\u003e[About the Jade Seal (Yu Xi) Variety]\u003c\/b\u003e\u003c\/h3\u003e\n\u003cp data-path-to-node=\"11\"\u003eThe Yu Xi, translating to \"Jade Seal\" or \"Imperial Seal,\" is a majestic variety revered for its imposing aesthetic.
