2. Observe the color: under the light of mobile phone, real agate generally appears bright and shiny orange or brownish red, and the color is even and bright.

3, observe the pattern: natural agate has agate patterns, mostly concentric patterns.

4. Observe the texture: the real agate is warm and moist, slightly messy inside, with a light colloidal texture, translucent state, waxy luster and relatively heavy.
