There are many ways to identify the authenticity of crystals, but here are some of the most common ones:
Observe the color and transparency of the crystal: Real crystals usually exhibit natural white or colorless transparency, while fake crystals can be too bright or cloudy. At the same time, there may be tiny impurities or textures inside the real crystal, which is one of the characteristics of natural crystals.
Check the hardness of the crystal: Real crystals have a higher hardness and will not leave marks when scratched with ordinary metal, while fake crystals may be softer and easy to leave marks.
Smell the smell of crystals: Real crystals usually have no noticeable odor, while fake crystals may emit chemical or other odors.
Feel the weight of the crystal: Real crystals are denser and feel heavier in the hand, while fake crystals may be lighter.
Check the melting point of the crystal: Real crystals have a high melting point and will not melt easily when heated with fire, while fake crystals may have a lower melting point and melt easily.
Use a polarimeter: A polarizer can be used to detect the polarized light characteristics of crystals. Real crystals will show alternating light and dark changes under a rotating polarimeter, while fake crystals will not have this change.
Use a refractometer: A refractometer can be used to measure the refractive index of a crystal. Real crystals have a higher refractive index, while fake crystals may have a lower index.
Observe the internal structure of the crystal: The internal structure of real crystals is usually more complex, with tiny textures, color bands, etc., visible, while fake crystals may be more uniform or have no obvious internal structure.
Conduct chemical tests: For some high-grade crystals that are difficult to identify, such as amethyst, citrine, etc., chemical tests can be used to identify their authenticity. For example, amethyst differs from purple glass in chemical composition and can be chemically tested using dilute hydrochloric acid.
Observe the growth lines of crystals: Natural crystals often have unique growth patterns and structural characteristics that can be observed under a magnifying glass. For example, white crystal balls often have hexagonal growth patterns that are difficult to imitate in fake crystals.
Observe the glossiness of the crystal: Real crystals usually have a high gloss with a smooth and moisturizing surface, while fake crystals may be dull or lacking in luster.
Check the electrical conductivity of the crystal: Natural crystals usually have good electrical conductivity and can be used to make electronic components, while some fake crystals do not have this conductivity.
In short, the identification of crystal authenticity requires a comprehensive consideration of a variety of factors, including color, transparency, hardness, odor, weight, melting point, internal structure, chemical composition, etc. If you find it difficult to verify the authenticity of your crystal, it is advisable to seek the help of a professional forensic agency.
