How is the purity of emerald estimated?
What determines the purity of emeralds?
The cost of emerald directly depends on the saturation of the green color and the purity of the gemstone. When identifying a class of minerals, gemologists consider the following structural parameters:
- Visual defects of the crystal - surface heterogeneity, the presence of cracks and chips on the coating.
- Metric parameters of foreign bodies in emerald.
- Location of inclusions in the structure of the mineral.
- Tint organic inclusions.
This is the only precious stone in the world, the price of which is determined solely by visual characteristics - color saturation and transparency.
