How to identify real original ruby

Ruby (a variety of corundum) is highly valued for its deep red color and durability. However, due to the presence of synthetic and imitation stones in the market, it is important to carefully verify its authenticity.

Tips to Identify a Genuine Ruby

1. Natural Inclusions
Most natural rubies contain small internal inclusions (often called “silk”). A completely flawless ruby is extremely rare and usually very expensive. If a stone looks perfectly clean at a low price, it may be synthetic or glass-filled.

2. Hardness Test (With Caution)
Ruby ranks 9 on the Mohs scale, making it very hard. However, scratching tests are not recommended, as they can damage the stone or mounting. Proper testing should be done by professionals.

3. Check for Bubbles
If you see round air bubbles inside the stone under magnification, it is likely glass or synthetic. Natural rubies do not contain gas bubbles.

4. Magnification Test
Under a magnifying glass or microscope, genuine rubies show natural patterns, inclusions, or needle-like structures. Synthetic stones often appear too perfect or show curved growth lines.

5. Color and Light Reflection
A real ruby displays a rich red color with natural depth. It may show slight variations in tone under light. Overly bright, uniform, or unnatural colors can indicate imitation stones.

6. Laboratory Certification
The most reliable way to confirm authenticity is through a certified gemological laboratory. Always prefer gemstones that come with proper certification.

By following these guidelines, you can better evaluate whether a ruby is genuine. For high-value purchases, always rely on certified testing and trusted sellers.
