7 Effective Ways to Tell if a Sapphire Is real

Sapphires are a popular gemstone that is prized for their beauty and durability. However, not all sapphires are created equal, and some may be fake or synthetic. If you’re in the market for a sapphire, it’s important to know how to tell if it’s real or not. In this article, we’ll go over what to look for when determining if a sapphire is genuine.

What is a Sapphire?

Before we dive into identifying a genuine sapphire, it’s essential to understand what a sapphire is. A sapphire is a type of mineral called corundum, which is second only to diamonds in hardness. The color of a sapphire can vary from blue to pink, yellow, green, purple, and even white. Sapphires are commonly used in jewelry, and they have been popular throughout history.

Look at the Color

The color of a sapphire is one of the most important factors in determining whether it’s real or not. Genuine sapphires will have a consistent color throughout the stone, while fake sapphires may have uneven coloring. Additionally, natural sapphires tend to have subtle variations in their color, while synthetic sapphires may have an artificial-looking color that appears too perfect.

Consider the Clarity

Another factor to consider when examining a sapphire is its clarity. Real sapphires will typically have some inclusions or imperfections inside the stone. These imperfections are a sign that the sapphire is natural and hasn’t been artificially created. Synthetic sapphires, on the other hand, may look too perfect without any visible inclusions.

Check the Cut

The cut of a sapphire can also provide clues as to whether it’s real or fake. Natural sapphires will typically have a cut that emphasizes the stone’s color and clarity. A poorly cut sapphire may be a sign that it’s synthetic or fake. In contrast, fake or synthetic sapphires may have a uniform cut, which makes them appear too perfect.

Examine the Transparency

The transparency of a sapphire is another factor to consider when determining its authenticity. Natural sapphires will typically have some degree of transparency, allowing you to see into the stone. In contrast, synthetic sapphires may appear cloudy or opaque.

Check for Scratches

Sapphires are incredibly hard, but they can still get scratched over time. If you’re examining a sapphire, check for scratches on the surface of the stone. Genuine sapphires will have fewer scratches than synthetic ones, as they’re less likely to become damaged.

Perform a Water Test

One simple test you can perform at home to determine if a sapphire is real or not is the water test. Fill a glass with water and drop the sapphire into it. If the sapphire sinks to the bottom of the glass, it’s likely genuine. If it floats or doesn’t sink all the way to the bottom, it may be synthetic.

Get a Certification

If you’re still unsure whether a sapphire is real or not, consider getting a certification from a reputable gemological institute. The Gemological Institute of America (GIA) is one of the most well-known institutions for gemstone certifications. A GIA certification can provide peace of mind that the sapphire you’re purchasing is genuine.


Determining whether a sapphire is genuine can be tricky, but there are several factors you should consider when examining a stone. Look at the color, clarity, cut, transparency, and scratches on the surface to determine whether the sapphire is natural or synthetic. Additionally, perform a water test or consider getting a certification from a reputable gemological institute. By taking these steps, you can ensure that you’re purchasing a genuine and high-quality sapphire.
