Gemstones are one of the beautiful types of stones and carry profound feng shui value. So how can you accurately identify natural gemstones in the wild? Let Jemmia explore 5 simple and accurate ways to identify natural gemstones in the article below. 

Why is it necessary to distinguish natural gemstones from fake stones?

Natural gemstones are formed over millions of years deep within the earth, possessing unique beauty and high value. The most popular gemstones today are: Diamond, Ruby, Sapphire, Emerald,... The characteristics of all types of rough gemstones are rarity, durability, and natural beauty.

In reality, it is necessary to distinguish natural gemstones from fake gemstones. The reasons are: 

  • Ensure value: Natural gemstones are rare and highly valuable; fake stones are cheap and have no storage value.

  • Avoid financial risks: Helps avoid buying fake stones at high prices.

  • Feng shui meaning: Natural stones carry positive energy, while fake stones do not have this characteristic.

5 ways to identify natural gemstones

Observe with the naked eye

Observing with the naked eye is the simplest and easiest way to identify natural gemstones. Based on color, transparency, light, and vein characteristics, you can distinguish natural stones from artificial ones at first glance.

  • Color: Natural gemstones have vivid colors but are not completely uniform, while artificial stones often have overly perfect color.

  • Transparency and light: Natural stones usually have moderate transparency and are not completely perfect because they contain natural impurities.

  • Stone veins: Natural gemstones have uneven veins, different from artificial stones, which are often uniform.

Check hardness

Checking hardness is one of the common ways to determine natural gemstones, because each type of stone has its own distinct hardness level. This helps you distinguish real stones from fake ones through their scratch resistance and durability.

  • Mohs scale: This is the standard for measuring gemstone hardness. Diamond is the hardest stone with a hardness of 10 on the Mohs scale, while quartz only reaches 7. This test helps you accurately determine the type of stone.

  • Simple test: Natural stones have higher scratch resistance. For example, diamonds can scratch the surface of many other types of stones, but very few can scratch a diamond. This is a characteristic sign of natural stones.

Light testing method

Light testing is an effective way to identify natural gemstones, because each type of stone reflects and disperses light differently. Natural stones usually offer a more refined and profound beauty than artificial stones.

  • Light reflectivity: Natural stones can reflect light in multiple directions, creating a unique sparkle. For example, natural diamonds disperse light into brilliant rainbow colors, while artificial diamonds may lack this vibrancy.

  • Compare the sparkle: Artificial stones often reflect light evenly and lack depth. For example, cubic zirconia stone (CZ) – a common fake stone – has sparkle but is less refined and can easily be recognized when placed next to a real diamond.

This method not only helps you distinguish natural stones from fake ones but also highlights the value and beauty of real gemstones.

Check with specialized tools

Using specialized tools is the most scientific and reliable method for determining natural gemstones. These devices allow accurate testing of the stone's physical and chemical properties.

  • Gemstone tester: A diamond tester is a common tool used to check thermal conductivity, helping distinguish natural diamonds from fake stones such as Moissanite or Cubic Zirconia. In addition, a clarity meter helps identify internal flaws, a characteristic commonly found in natural stones.

  • Spectral analysis: This method checks the stone's reflected and absorbed light to determine its chemical composition. For example, the spectrum of a natural diamond has distinct characteristics, completely different from artificial or imitation stones.

Ask an expert for appraisal

Seeking an expert appraisal is the most reliable way to determine natural gemstones. Experts not only have extensive knowledge but also use modern tools to provide accurate evaluations.

Go to reputable organizations such as GIA (Gemological Institute of America) or IGI (International Gemological Institute) to have the stone checked and receive a quality certificate. These centers apply international standards, ensuring transparency and credibility.

Frequently asked questions

How can I know if the gemstone I bought is natural?

Check using methods such as observing color, stone veins, hardness, light reflectivity, or using specialized tools. The best option is to have it appraised at reputable centers such as GIA or IGI.

Do artificial stones have value?

Artificial stones have aesthetic value but do not have storage or investment value like natural stones, because they are industrially produced and not rare.

Why do natural stones have uneven veins?

Uneven veins are the result of natural formation processes under high pressure and temperature, creating unique and distinctive characteristics in each stone.

Should I buy gemstones at the market?

No, because products at the market often do not guarantee origin and quality. Choose to buy from reputable stores or brands with clear appraisal certification.

Understanding how to identify and buy natural gemstones not only helps you own products with real value but also avoids unnecessary risks. Always inspect carefully, buy from reputable addresses, and request appraisal certificates from trustworthy organizations.
