I was looking online for description of some woods that I have in my humble collection, and found this. The video says 1g of kyara is about 15,000 yen. The video must have been made a few years ago; it is now (2016) no less than 40,000 per gram. Don't miss the photos of the photos of the 61 famous pieces of wood from 500 to 600 years ago, and Ranjatai, the most famous piece of fragrant wood revered for its supreme fragrance from the 595, 700's, or after the 10th century, depending on who you believe. In any case, it's old!
