Simple naming (lol). Because of its shape resembling a rice bale, it's called "Tawara-ishi" (Rice Bale Stone). Young people might ask, "What's a rice bale?" This is petrified wood from Ishizawa, Yuri Honjo City, Akita Prefecture. The center of the annual rings can be observed, and despite their small size, the rings are very fine. Perhaps it grew in a very cold era? Roughly 50 years or more. The brownish-red parts at both ends have become agate. It will shine if polished. Size: Height: Approximately 8cm Circumference (widest part): Approximately 7.1cm Circumference (narrowest part): Approximately 5cm Weight: 427g Shipping will be via Rakuraku Mercari Bin or Kuroneko Yamato Takkyubin (home delivery service), and it will be packed compactly with simple packaging. Thank you.
