How to Identify Lab Certified Gemstones – Complete Buyer’s Guide
Introduction: Why Certification Matters in Gemstone Buying
In the world of gemstones, looks can be deceiving. What may appear stunning to the naked eye could be a synthetic or heat-treated imitation with zero astrological benefits. If you’re planning a gemstone online buy, ensuring it is a lab certified gemstone is not just a good idea—it’s essential.
Whether you are buying for astrological purposes, healing, or investment, natural gemstones work only when they are genuine, untreated, and certified by a recognized gemological laboratory.
What is a Lab Certified Gemstone?
A lab certified gemstone is a natural stone that has been evaluated and authenticated by an independent gemological lab. This certification confirms that the stone:
-
Is natural, not synthetic
-
Has not been heat-treated or chemically enhanced
-
Matches the specifications (carat, clarity, origin, etc.)
-
Is suitable for astrological use if applicable
Some of the most trusted gem labs in India include:
-
GII (Gemological Institute of India)
-
IGI (International Gemological Institute)
-
GRS
-
IGL
-
BIS Hallmark labs (for precious metals + gems)
Why Natural Gemstones Need Certification
Natural gemstones form deep within the Earth over millions of years. Their energy, color, and crystal structure are aligned with planetary powers, making them powerful tools in Vedic astrology.
However, due to increasing demand, the market is full of:
-
Synthetic gemstones (lab-created imitations)
-
Glass-filled or heat-treated stones
-
Dyed quartz or colored glass being sold as emeralds, sapphires, etc.
Hence, certification is the only way to ensure authenticity.
How to Read a Gemstone Lab Certificate
Before you buy, always ask for the certificate and learn how to interpret it.
Here are the main elements you should check:
| Label | What to Look For |
|---|---|
| Gem Type | Clearly mentioned (e.g., Natural Blue Sapphire) |
| Weight | Measured in carats (e.g., 5.25 ct) |
| Cut & Shape | Oval, cushion, round, etc. |
| Color | Authentic natural hue |
| Treatment | Must say “None” or “Untreated” |
| Origin | Optional, but Sri Lanka, Zambia, etc. are good |
| Lab Name & Seal | Should be GII, IGI, or recognized lab |
| Report Number | Unique ID for tracking |
Pro Tip: Verify certificate authenticity by checking it on the lab’s official website using the report number.
Lab Certified Gemstone vs Non-Certified – What’s the Risk?
| Certified Gemstone | Non-Certified Gemstone |
|---|---|
| Verified as natural and untreated | Could be synthetic or artificially treated |
| Accurate pricing based on quality | Overpriced or underpriced, no benchmark |
| Eligible for astrological use | May offer zero results |
| Resale value and transparency | Difficult to resell |
| Comes with guarantee & trust | Total risk on the buyer |
Tips to Identify Fake Gemstones (Without Lab Tools)
Although lab certification is the most reliable way, here are some basic signs of a fake gemstone:
-
Perfect Clarity and Color
Natural gemstones usually have minor inclusions. If it looks too perfect, it might be fake. -
Too Cheap for the Type
Genuine sapphires, emeralds, or rubies are never dirt cheap. Low prices often mean imitations. -
No Inclusions at All? Be Suspicious
Even the highest quality gems have some inclusions under magnification. -
Unusual Glow Under UV Light
Fake or synthetic gems often glow unnaturally under ultraviolet light.
