To judge natural zircon, you can consider the following aspects:
1. Color: The color of natural zircon is usually more natural and uniform, and there is no strong sign of artificial dyeing. Common natural zircon colors include colorless, white, yellow, pink, brown, and so on.
2. Refractive index: Natural zircon has a relatively high refractive index, about 2.15 to 2.18. You can use a professional refractometer to measure the refractive index of the zircon to determine whether it is a natural zircon.

4. Markings and streaks: There may be some markings, streaks or textures on natural zircon, which are usually formed by alternating magma deposition and residue in the process of crystal growth. Artificial zircons tend to be more uniform, with no obvious markings or streaks.
5. Professional appraisal: The most reliable way to determine whether it is a natural zircon is to seek the help of a professional appraisal institution or appraisal master. They can use more accurate and scientific testing methods, such as microscope observation, Raman spectral analysis, etc. to identify the authenticity of the zircon.
It should be noted that in order to avoid the purchase of fake artificial zircon, it is recommended to buy in a jeweler with a high degree of credibility, and keep the purchase certificate and certificate for verification.
