Amblygonite is found in a wide range of colors from white, pink, green, and blue to golden yellow and, more rarely, colorless. Large, transparent to translucent crystals may occur, but, as amblygonite is relatively soft, they are cut solely for collectors. Amblygonite is also found as cleavable or compact masses.

Amblygonite is found in pegmatite's, Brazil is the source of most gem-quality material, but it is also found in the USA. A pale mauve variety occurs in Namibia.

Amblygonite has been confused with brazilianite and scapolite.
