The mineral is a fluophosphate which like topaz, has the fluorine replaceable by the hydroxyl group.

Amblygonite is prismatic to columnar in form with good cleavage is in several directions. The fracture is irregular- uneven or sub-conchoidal. The luster is vitreous to pearly and faceted stones are very rarely clean. Amblygonite is biaxial and may be either positive or negative. The birefringence values range from .020 - .027 and pleochroism is weak or unobservable. Ultraviolet fluorescence may be a very weak green in long wave along with some light blue phosphorescence in long wave and short wave UV.
