How do you tell if a sapphire is real

Sapphires are one of the most coveted gemstones in the world, prized for their beauty, durability, and rarity. However, there are many fake sapphires on the market, which can be difficult to distinguish from the real thing. If you are considering purchasing a sapphire or have one in your collection, it is important to know how to tell if it is real. In this article, we will discuss some tips on how to identify a genuine sapphire.




The color of a sapphire is the most important factor in determining its value and authenticity. Genuine sapphires come in a range of colors, including blue, yellow, pink, purple, and green. The color should be consistent throughout the stone, with no visible zoning or patches of different colors. If the color looks too perfect or is too bright, it may be a synthetic or treated stone.


Sapphires can have natural inclusions, which are tiny imperfections within the stone. However, genuine sapphires should not have any visible cracks, bubbles, or scratches on the surface. If the stone appears cloudy or has visible flaws, it may not be a genuine sapphire.


The cut of a sapphire can also indicate whether it is real or fake. A genuine sapphire will have clean, sharp edges and symmetrical facets. If the stone appears dull or poorly cut, it may be a synthetic or treated stone.


Sapphires are one of the hardest gemstones, ranking at a 9 on the Mohs scale. This means that they should not scratch easily, and should be able to scratch other materials such as glass. If the stone scratches easily or is damaged by simple household objects, it may not be a genuine sapphire.

Heat Treatment

Many sapphires are heat-treated to enhance their color or clarity. While this is a common practice in the gemstone industry, it can make it difficult to determine whether a sapphire is genuine or not. However, if the price of the sapphire seems too good to be true, it may be a sign that it has been treated or is a synthetic stone.

In conclusion, there are several ways to tell if a sapphire is real, including examining its color, clarity, cut, hardness, and heat treatment. If you are unsure about the authenticity of a sapphire, it is always best to consult with a reputable gemologist or jeweler who can help you determine whether the stone is genuine or not. By taking the time to properly examine and identify a sapphire, you can ensure that you are getting a high-quality and valuable gemstone.
