The gemstone’s specific gravity is 3.99, the mean refractive index (RI) is 1.765, and the hardness of 9 on Moh’s scale.
Like other gemstones, yellow sapphire or pukhraj have some inclusions visible to the naked eye or under magnification. An original yellow sapphire gemstone often has feather-like inclusions. Sometimes it has fingerprint-like and lace-like impressions visible. If you ever find a yellow sapphire free from inclusions, it is either a piece of glass or a synthetic substance.

Tips to Identify Lab-Certified Pukhraj Stone
If you are picky with gemstones, yellow sapphire is a gorgeous choice to bring light to the day. However, often some gemstone dealers fool customers by selling fake stones. Therefore, it is essential to opt for lab-certified Yellow sapphire gemstones. How do you identify if your gemstones are lab certified? Most lab certified gemstones occur originally. Here are some tips for determining if your favorite gemstone underwent lab certification.
Comparing it with Yellow Glass
I came across most people claiming yellow sapphire resembles yellow glass. One of the easiest ways to check if you opted for a real gemstone is to compare it to a piece of yellow glass. Is there any difference? Of course, the difference is drastic. Your lab certified yellow sapphire gemstone has rich shading and clearness, and the piece of glass will give a pale look.
Presence of Bubbles
An original pukhraj comprises inclusions that can only be visible under a microscope. You cannot see them with your naked eyes. However, it might be fake if you notice tiny bubbles or a substance resembling a liquid glass.
From the natural paste of light yellow and lemon yellow to deep and golden yellow, yellow sapphire gemstone comes in various hues. However, the most common color certified by gemstone labs is the vibrant yellow or canary yellow shade having excellent color consistency. The brighter and purer the color, the more valuable your pukhraj.
The cut is another aspect that enhances the beauty of the stone. By cut, we refer to the facets present on the gemstone. Round, oval, cushion, pear, emerald, or heat, whatever cut you opt for, the gemstone allows passage of light, offering a unique sparkle and color. When purchasing yellow sapphire stone, look for any “X” sign or scissor cut on the facet. Original and lab certified stones do not have any such marks on their stone.
Check for the Scratches
Lab tested and certified yellow sapphire gemstones are free from any scratch. Moreover, pukhraj is an unbending and hard stone ranking 9.0 on the Mohs hardness scale. The only stone higher on the scale is diamond at 10.0. Furthermore, if you find even a minute scratch on the stone, rest assured that it’s fake.
Check for Fillings
Many stones include negative spaces and inclusions, and yellow sapphire is not an exemption. These imperfections result from cutting the gemstones and developing a small hole. Most jewelers and lab tested yellow sapphires have the hole's presence, proof of the gemstone's authenticity. Checking for the filling is simple. Just shine a light on the stone to examine it. If you find any uneven patches, it’s an indication of fillings within them. Avoid going for stones having fillings.
Check for Warmth
Are you dealing with a loose stone? You can hold it in your hand and check for its authenticity. When you hold a real and lab certified sapphire, you can feel the warmth on your palm. On the other hand, the stone might be synthetic and fake if you do not feel anything.
Ask for Certificate
It’s probably the easiest way to check the authenticity of your gemstone. A lab certified yellow sapphire comes with a certificate signed and stamped by the gemologist and the laboratory.
Most people love possessing yellow sapphire gemstones or pukhraj because of their bright and cheerful color. Whether you are choosing the best sapphire for your astrology ring, engagement ring, wedding necklace, or bracelet, ensure to check and opt for a lab certified original gemstone. Hope the article helped you choose the best real pukhraj for your purpose.
