Having a well-formed or clearly defined crystalline structure that can be easily observed and studied.
From Greek eu- (well) + crystalline, meaning 'properly crystallized.' It contrasts with cryptocrystalline (hidden crystals) and describes minerals where the crystal structure is obvious to the naked eye or under basic magnification.
Geologists use eucrystalline to describe rocks like granite where you can actually see the individual crystals with your eyes—this is one of the most satisfying aspects of geology, as you're literally watching nature's perfect geometric patterns.
