It earns its poetic name from its original geographic origins near the rugged rocky valleys of the Nanjiang region, where the wild trees produced walnuts with shells so extraordinarily dense they felt like solid stream stones. Advanced collectors prize this lineage above almost all others for its classic structural markers: featuring broad dropped shoulders, thick sweeping outer edges, and a deeply set concave base layout. This robust variety is highly responsive to natural skin lipids, transforming over a dedicated handling journey into a deep, high-gloss translucent oxblood-red ruby patina.\u003c\/p\u003e\n\u003ch3 data-path-to-node=\"13\"\u003e\u003cb data-path-to-node=\"13\" data-index-in-node=\"0\"\u003e[Product Characteristics of NJS-1004]\u003c\/b\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli data-path-to-node=\"14,0,0\"\u003e\n\u003cb data-path-to-node=\"14,0,0\" data-index-in-node=\"0\"\u003eThe Commanding 40mm 1:1 Isometric Geometry:\u003c\/b\u003e Measuring a substantial 40.0mm across the wide primary borders paired with an identical 40.0mm belly depth.
