The density of turquoise is between 2.6 and 2.9, and the density of the aragonite is between 2.53 and 2.56. Therefore, the two stones of the same volume are of turquoise quality and the light weight is Tianhe stone. Or when the mass is the same, the large volume is the Tianhe stone, and the small volume is turquoise. 3. Refractive index. The refractive index of turquoise is 1.62, and the refractive index of Tianhe stone is between 1.52 and 1.57.
