1.Check the surface characteristics of the gemstone: growth patterns, etching, scratches, damages, symmetry, and mating surfaces (bubbles, gloss differences) of the gemstone, etc
2.Observing the internal characteristics of gemstones: types, shapes, quantities, twin planes, growth patterns, color distribution characteristics, initial cleavage, defects, etc. of inclusions
3.Observing the facet shadow of gemstones: Gems with high birefringence, such as zircon(DR=0.059)Olivine(DR=0.036)Tourmaline(DR=0.078) Observation of the dark field and polarized light phenomena of the facets and edges of gemstones, used to analyze the various components and characteristics of gemstones.
