Pink sapphires are beautiful and valuable gemstones, but unfortunately, there are many imitations in the market. It’s important to be able to tell the difference between a real pink sapphire and a fake one. There are several methods you can use, ranging from simple visual inspections to more advanced tests.
Visual Inspection
Intensity and Uniformity of Color
A real pink sapphire usually has a natural – looking color. The intensity of the pink should be consistent throughout the stone. If the color looks too bright, fluorescent, or uneven in an artificial way, it might be a fake. For example, a synthetic pink sapphire created through certain processes may have a color that is overly vivid and lacks the subtle variations found in natural stones. In a real pink sapphire, the color may be deeper in some areas and lighter in others in a smooth gradient.
Color Hue
The hue of a genuine pink sapphire can vary from a light pastel pink to a vivid hot – pink. However, there are certain hues that are characteristic of natural pink sapphires. If the color looks too artificial, like a color that you would not typically see in nature, it could be a sign of a fake. For instance, some fake pink sapphires may have a pink color that is more like a painted – on or dyed appearance, rather than the natural color that comes from the gemstone’s chemical composition.
Inclusions and Internal Features
Natural Inclusions
Most real pink sapphires have inclusions. These can be small crystals, gas bubbles, or other imperfections within the stone. Under a 10x loupe or a microscope, you can look for these inclusions. Natural inclusions in pink sapphires are usually irregular in shape and size. They may be scattered throughout the stone in a random pattern. For example, you might see tiny needle – like rutile inclusions that give the sapphire a silk – like appearance under certain lighting conditions.
Absence of Suspicious Inclusions
On the other hand, if the stone is completely clear and free of any inclusions, it could be a sign of a synthetic or fake pink sapphire. However, some high – quality natural pink sapphires can be relatively free of visible inclusions, so this is not a definitive test. But if you see perfectly spherical bubbles or evenly spaced inclusions that look too regular, it’s likely that the stone is not genuine. These types of inclusions are often found in synthetic gemstones created by certain manufacturing methods.
Hardness and Durability Tests
Scratch Test
Pink sapphire has a hardness of 9 on the Mohs scale. You can try a simple scratch test with a material of known hardness. For example, a piece of quartz (hardness 7) should not be able to scratch a real pink sapphire. Gently try to make a small scratch on an inconspicuous part of the stone with the quartz. If the stone gets scratched easily, it’s probably not a real sapphire. However, be careful not to damage the stone during this test as it can affect its value if it is genuine.
Avoiding Damage to the Stone
It’s important to note that this test should be done with extreme caution. If you’re not sure, it’s better to skip this test or consult a professional. You can also use other materials with different hardness levels around the Mohs scale value of 9, like topaz (hardness 8) to further confirm the hardness of the stone. But always remember that any test that involves scratching the stone can potentially reduce its quality.
Durability in Daily Wear
Resistance to Abrasion
A real pink sapphire should be able to withstand normal daily wear without showing signs of damage. If you’ve been wearing a piece of jewelry with a pink sapphire for a while and notice that the stone is getting scratched or chipped easily, it might be a fake. Real pink sapphires are used in high – quality jewelry because of their durability. They should be able to hold up well against contact with other objects like keys, coins, and clothing.
Long – term Stability
Over time, a genuine pink sapphire should maintain its color and clarity. If you notice that the color of the stone is fading or changing, or if it starts to look cloudy or less transparent, it could be an indication that it’s not a real sapphire. Some fake gemstones may be made from materials that are not stable and can be affected by exposure to light, heat, or chemicals.
Conclusion
Telling if a pink sapphire is real requires a combination of different methods. Visual inspection can give you some initial clues, but more accurate results can be obtained through hardness tests, optical tests, and advanced testing methods. For valuable gemstones, it’s always best to consult a professional or send the stone to a gemological laboratory. By being able to identify real pink sapphires, you can ensure that you are getting the quality and value you expect when purchasing or evaluating these beautiful gemstones.
