This is a Vietnamese agarwood, a top-grade Kyara, obtained from producers in Nha Trang, central Vietnam, before the 1995 Washington Convention. Historically, it has been highly valued in Japan as "Vietnamese Kyara Agarwood." Instead of a cloying sweetness, it offers a clear, pure fragrance that invites tranquility. Professionals should be able to assess its value based on the color, luster, and shape shown in the photos. This is agarwood I have collected over many years.
