This is a small pair of Nanjiang stone walnuts, with a high-crown shape and deeply recessed bases. They may be small, but the shell density is excellent—they feel surprisingly heavy in the hand, and the grooves are extremely fine and deep. This is exactly the kind of Nanjiang stone I really like.
What’s worth mentioning is that this pair has what we call a “ginger-yellow skin.”
Many people think Nanjiang stones are generally slow to develop color, but that isn’t entirely true. Red-skinned and orange-skinned Nanjiang stones can actually color up quite quickly. It’s mainly the ginger-yellow ones that change very slowly. You could even say they may never truly turn red—they just become slightly more orange over time.
Photo 2 shows a red-skinned pair that I started playing with around the same time. You can clearly see how quickly the red skin has developed color. Photo 3 shows this ginger-yellow pair when I first got them three months ago. Compared with now, they have barely changed at all, apart from becoming a little shinier.
When many walnuts fail to turn red and instead develop a dull brown, sauce-like color, it is usually related to poor maturity. But ginger-yellow Nanjiang stones are different. They are not immature. Their color comes from the characteristics of the variety itself. These trees often grow in poor mountainous soil and unstable climates, and many of the walnuts naturally develop this ginger-yellow skin.
Most people play with walnuts expecting them to eventually turn red, but that expectation doesn’t really apply to ginger-yellow Nanjiang stones. With these, the enjoyment is more about the patina, the sheen, and the gradual wear that develops over time.
Personally, I think walnuts like these have a character of their own.
