How can I tell Lapis lazuli and Turquoise apart?
There are several visual cues: both appear blue, but often in different saturations; Lapis lazuli has a vitreous,greasy luster compared to Turquoise's waxy,dull (earthy) luster; Turquoise (RI 1.61-1.65) shows more brilliance than Lapis lazuli (RI 1.5-1.67); they have different crystal systems — Lapis lazuli is Isometric and Turquoise is Triclinic. A gemologist can confirm identification using refractive index testing.
Why do Lapis lazuli and Turquoise look similar?
Lapis lazuli and Turquoise look similar because both gems display blue hues.
