A gemgarnet from Otterøy by Molde, Western Norway, is described. The garnet display an \"alexandrite-like effect\", i.e. the colour varies with the nature of the incident light. The transmission curves shows absorbtion peaks at 5600 Å and at 4000 Å. The refractive index is l,747 +- 0,001. The cell size = 11,54 +-0,01 Å. A determination of the spesfic gravity gave 3,715 +- 0,005.
