Gemstones have been used for centuries for their beauty, rarity, and symbolic meanings. With the advent of the internet, it has become easier to purchase gemstones online, but identifying their authenticity and quality can be challenging. In this article, we will discuss how to identify gemstones online using various tools and techniques.
Use a Gemological Database
The first step in identifying a gemstone is to use a gemological database. There are several databases available online, such as the Gemological Institute of America (GIA) and the International Gem Society (IGS). These databases provide detailed information on the characteristics and properties of different gemstones, such as their color, hardness, and refractive index. By cross-referencing these characteristics with the gemstone in question, you can begin to identify it.
Conduct a Visual Inspection
A visual inspection is the next step in identifying a gemstone. Look for any distinguishing characteristics, such as color, clarity, and inclusions. Use a magnifying glass or jeweler's loupe to examine the gemstone more closely. Inclusions, or imperfections inside the gemstone, can help identify the type of gemstone. For example, a ruby may have needle-like inclusions known as "silk."
Test the Hardness
Another way to identify a gemstone is by testing its hardness. The Mohs scale is a system that measures a mineral's hardness on a scale of 1 to 10. For example, diamond has a hardness of 10, while talc has a hardness of
By testing the hardness of the gemstone in question, you can eliminate certain types of gemstones. For example, if the gemstone scratches easily with a fingernail, it is likely not a diamond.
Check the Refractive Index
The refractive index is a measure of how much light bends when passing through a material. Gemstones have unique refractive indexes that can help identify them. To test the refractive index of a gemstone, place it on a flat surface and shine a light through it. The light should refract or bend, and the angle of the bend can be measured.

Use a Gemstone Identification Tool
There are several gemstone identification tools available online that can help identify gemstones. These tools include spectrometers, refractometers, and polariscopes. These tools use advanced technology to analyze the gemstone's characteristics and provide a detailed report on its identity. While these tools can be expensive, they are highly accurate and can be a worthwhile investment for gemstone enthusiasts.
Consult with a Gemologist
If you are still unsure about the identity of a gemstone, it is best to consult with a gemologist. A gemologist is a trained professional who specializes in the study and identification of gemstones. They can use their expertise and specialized equipment to identify the gemstone and provide a detailed report on its characteristics and value.
