1. What Is Gemstone Certification?
A Gemstone Certificate (also called a Gem Identification Report) is an official document issued by a gemological laboratory that confirms a gem’s identity, authenticity, and characteristics.
It includes:
- Gem type (e.g., Ruby, Sapphire, Emerald)
- Natural or synthetic origin
- Treatments (if any)
- Weight, color, and clarity
- Magnified image of the gemstone
- Unique report number for verification
💎 In short: A certified gemstone comes with proof of what it truly is — and what it isn’t.
2. Why Gemstone Certification Matters
Buying a gemstone without certification is like buying a car without a registration — you can’t be sure of what you’re getting.
Top Reasons to Get Certification:
- Authenticity: Confirms the gem is natural and not synthetic or imitation.
- Transparency: Reveals any treatments, such as heating or dyeing.
- Value Assurance: Helps determine fair pricing.
- Trust: Builds credibility for sellers and confidence for buyers.
- Resale Proof: Certified gems are easier to resell and insure.
A certificate from a trusted gem lab like GemLabTesting.com ensures your gemstone meets professional gemological standards.

3. Step-by-Step Gemstone Certification Process
Here’s how the process works at GemLabTesting.com — simple, transparent, and science-backed:
Step 1: Submission of the Gemstone
Customers, jewelers, or dealers submit their gemstone to our testing laboratory.
- You can visit our lab in person or send your gem via secure courier.
- Each stone is given a unique code and safely sealed for traceability.
Step 2: Preliminary Inspection
Our gemologists perform an initial visual inspection to:
- Identify the gem type
- Examine its color, transparency, and luster
- Check for visible inclusions or surface features
This helps determine which advanced tests are required next.
Step 3: Advanced Gemological Testing
At this stage, we use state-of-the-art instruments to study the gem’s physical and optical properties.
Common tests include:
| Test Type | Purpose |
|---|---|
| Refractive Index (RI) | Measures how light bends through the gem — identifies the type of gemstone |
| Specific Gravity (SG) | Determines gem density to differentiate similar-looking stones |
| Microscopic Examination | Reveals inclusions, growth lines, or treatments |
| UV Fluorescence | Helps detect synthetic or treated gems |
| Spectroscopy | Analyzes absorption patterns unique to each gem |
| Magnification & Microscopic Imaging | Captures internal features for report accuracy |
These tests confirm whether the gemstone is natural, treated, or synthetic.
Step 4: Identification & Grading
After testing, our experts identify and grade the gemstone based on:
- Color – hue, tone, and saturation
- Clarity – presence of inclusions or surface blemishes
- Cut – precision and symmetry
- Carat Weight – measured using a precision balance
This grading ensures your gemstone’s true market value is established scientifically.
Step 5: Origin & Treatment Detection
If the gemstone is found to be natural, additional analysis is done to detect:
- Country of Origin (e.g., Burma, Sri Lanka, Zambia)
- Treatments Applied (e.g., heat, oiling, diffusion)
Transparency about treatments is crucial — untreated stones often hold higher value than treated ones.
Step 6: Report Preparation & Verification
Once testing is complete, we prepare your official Gem Certificate.
It includes:
- High-resolution gemstone image
- Full identification and grading details
- Comments on treatments or enhancements
- A unique certificate number for online verification
- Authorized signature of a certified gemologist
You can easily verify your report online via GemLabTesting.com for authenticity.
Step 7: Delivery of Certificate
The final certificate is securely sealed and delivered to you — either in person or via courier.
Your gemstone is returned safely along with the report, ensuring transparency and trust at every step.
