Yamato Yoshino Unakite (Nara Prefecture) [Famous Japanese Stone]
Yamato Yoshino stone Unakite
Yamato Yoshino Unakite
Yamato can be said to be the birthplace of Japanese civilization.
This stone comes from a mysterious land where many ancient tombs and stone ruins still remain, shrouded in mystery.
It is one of the famous stones that has a deep red base and shows various expressions such as green, yellow-green, and black.
Along the Median Tectonic Line, the main components are chlorite, which is of the same series as the Solomonite in Tokushima Prefecture, and pale yellow-green epidote.
Unakite also contains feldspar.
However, what makes it different from other stones is that it contains a lot of volcanic iron, which oxidizes over time and gives it a vivid red color.
Since ancient times, they have been treasured as bonsai stones and garden stones, and those around the Yoshino River are particularly prized for their beauty.
