The name Keumgang means "diamond" or "indestructible". It symbolizes strength, invincibility and purity, like the diamond, the hardest material known. In Korean tradition, this word also refers to Mount Keumgang, a sacred mountain considered to be an embodiment of eternal strength and beauty. The Keumgang poomsae therefore embodies these qualities of immutability and stability, both physically and spiritually.

This poomsae aims to represent the spirit of a practitioner who, like a diamond, must be resilient in the face of challenges and maintain purity in one's intentions. It also symbolizes the idea of ​​quiet strength, a power that is harnessed and well directed, rather than simply raw.
