It's likely to be gabbro, a very common type of rock I'm afraid. Doesn't mean it can't be special to him!https://geology.com/rocks/gabbro.shtml
Yip definitely gabbro.OP, the light/ white mineral is plagioclase the dark almost black mineral is pyroxene.If you look at it in sunlight anything with a dark green colour is probably Olivine
