Top Ways to Identify a Real Yellow Sapphire

Top Ways to Identify a Real Yellow Sapphire

21 Mar, 2023 | Gemstone | Gem Selection

Yellow sapphires are a stunning addition to any jewelry collection, but it's important to be vigilant against fake stones. Don't be fooled by imitations - To ensure you're getting a genuine yellow sapphire, we've compiled a few tips for identifying the real deal. 

Ask for Certification 

The easiest way to check the authenticity of your stone is to ask for a certificate from a trusted organization. This guarantees that your stone has been examined and verified as authentic. 

Compare Using Yellow Glass

Another trick is to compare your stone to a piece of yellow glass - a genuine sapphire will have richer shading and clarity. Be sure to inspect your stone for any visible bubbles or scratches. Genuine yellow sapphires will have a rich color and clarity, while glass will appear pale in comparison.

Check for Bubbles

While some may argue that the two are similar, the difference is clear when placed side by side. Inclusions, or imperfections within the stone, should not be visible to the naked eye. If you notice tiny bubbles or liquid-like markings, it's likely a fake. 

Check for Scratches

Finally, yellow sapphires are incredibly hard stones, ranking at 9.0 on the Mohs hardness scale. If there are scratches on your stone, it's unfortunately not a real sapphire. By keeping these tips in mind, you can confidently invest in a beautiful yellow sapphire without falling victim to fraud.

The 'X' Sign

When it comes to yellow sapphires, it's important to know how to spot a phony. One telltale sign is the presence of an "X" cut, often found on fake gemstones.

Is it Groovy?

 Another way to check is to use a 10x loupe to look for grooves - a real sapphire should be completely smooth. 

Check for Fillings

Fillings can also indicate a fake, so be sure to examine your stone for uneven patches or imperfections. And finally, holding the stone in your hand can reveal its authenticity - a real sapphire should feel warm. By following these tips, you can ensure you're getting the real deal when it comes to yellow sapphires.
