The origins of the name “15th Rock”

In the stone garden of the Ryōan-ji temple in Kyoto, there exists a “fifteenth rock” which is concealed from view. Like that fifteenth rock, we seek to find and refine crude stones so that they can become world-changing diamonds. This is the hope on which 15th Rock was born.
