Thanks for sharing, I have always felt confused about the concept of ' 溫潤' of He-tian Jade until I found your footage. I'll make a better explanation to my foreign friend. Compared with transparency and variable colors of Fei-Cui, the surface of He-tian Jade( aka Nephrite) brings sort of fine, wax-like shinning which we called '溫', and oily sentiment we called '潤'. Great job. Two thumbs up.
