Yellow sapphire, also known as Pukhraj, is a highly valued gemstone in the world of jewelry. Its vibrant color and astrological significance make it a sought-after stone. However, with the rise of synthetic and imitation stones, identifying an original yellow sapphire can be challenging. This guide will walk you through everything you need to know to ensure you’re buying an authentic yellow sapphire.
What is Yellow Sapphire?
Yellow sapphire is a variety of the mineral corundum, which is also the base for rubies and other sapphires. Its yellow hue comes from trace elements of iron within the crystal structure. Natural yellow sapphires are rare and prized for their beauty and durability, ranking 9 on the Mohs hardness scale.
Why is it Important to Identify Original Yellow Sapphire?
Buying an original yellow sapphire ensures you get the value for your money. Fake or synthetic stones lack the natural properties and astrological benefits associated with genuine yellow sapphires. Additionally, original stones have better resale value and longevity.
Key Characteristics of Original Yellow Sapphire
1. Color
The color of a natural yellow sapphire ranges from pale yellow to deep golden hues. The most valuable stones have a vivid, uniform color without any brownish or greenish tints.
2. Clarity
Natural yellow sapphires often have minor inclusions, which are tiny imperfections inside the stone. These inclusions are like fingerprints, proving the stone’s authenticity. However, too many inclusions can reduce the stone’s value.
3. Cut
The cut of a yellow sapphire affects its brilliance and color distribution. Well-cut stones reflect light evenly, enhancing their natural beauty.
4. Carat Weight
Yellow sapphires are available in various sizes, but larger stones are rarer and more expensive. Ensure the carat weight aligns with the stone’s dimensions to avoid artificially inflated pricing.
5. Luster
Original yellow sapphires have a vitreous (glass-like) luster that gives them a shiny, polished appearance. Fake stones may appear dull or overly glossy.
How to Test the Authenticity of Yellow Sapphire
1. Visual Inspection
Examine the stone under a magnifying glass or jeweler’s loupe. Look for natural inclusions, uneven color distribution, and signs of wear. Synthetic stones often appear too perfect.
2. The Scratch Test
Yellow sapphires are extremely hard and can scratch glass. Gently rub the stone against a piece of glass. If it leaves a scratch, it’s likely genuine.
3. The Breath Test
Breathe on the stone to fog it up. An original yellow sapphire will clear up quickly, while a fake one will retain the fog for a longer time.
4. The UV Light Test
Under ultraviolet light, natural yellow sapphires may exhibit a faint glow. Synthetic stones often show a stronger, unnatural fluorescence.
5. Professional Gemological Testing
For absolute certainty, take the stone to a certified gemologist. They can perform advanced tests like spectroscopy and refractive index analysis to confirm authenticity.
Common Imitations and How to Spot Them
1. Glass Imitations
Glass imitations are common but lack the hardness and luster of real yellow sapphires. They may also have air bubbles or swirls inside.
2. Synthetic Sapphires
Lab-created sapphires have the same chemical composition as natural ones but are less valuable. They often lack inclusions and have an overly uniform color.
3. Yellow Topaz
Yellow topaz is sometimes mistaken for yellow sapphire but is softer and less durable. It also has a different refractive index.
4. Citrine
Citrine is a quartz variety with a similar color but is much softer and less valuable than yellow sapphire.
Tips for Buying Original Yellow Sapphire
1. Buy from Reputable Sellers
Always purchase from trusted jewelers or certified dealers who provide authenticity certificates.
2. Check for Certification
A genuine yellow sapphire should come with a gemological certificate from a recognized lab like GIA or AGS.
3. Compare Prices
If the price seems too good to be true, it probably is. Original yellow sapphires are expensive due to their rarity.
4. Ask Questions
Don’t hesitate to ask the seller about the stone’s origin, treatment, and certification. A reputable seller will be transparent.
Caring for Your Yellow Sapphire
1. Cleaning
Clean your yellow sapphire with warm soapy water and a soft brush. Avoid harsh chemicals or ultrasonic cleaners.
2. Storage
Store the stone separately to prevent scratches from other jewelry. Use a soft pouch or a lined jewelry box.
3. Regular Inspections
Have your yellow sapphire inspected by a jeweler annually to ensure its setting is secure and the stone is in good condition.
Conclusion
Identifying an original yellow sapphire requires knowledge, attention to detail, and sometimes professional assistance. By understanding its key characteristics, performing simple tests, and buying from reputable sources, you can ensure you’re investing in a genuine and valuable gemstone. Whether for its beauty or astrological benefits, an authentic yellow sapphire is a treasure worth cherishing.
