How to Check Rough Gemstones in Labs
If you have rough gemstones and want to get them checked in a lab, here's what you need to do:
1. Clean the stones: Gently clean your rough gemstones with warm water and mild soap. This helps the lab see the stones clearly.
2. Choose a lab: Pick a trusted lab from the list above or a local lab with a good reputation.
3. Contact the lab: Call or email the lab to ask about their services for rough gemstones. Some labs might have special rules for rough gems.
4. Prepare the stones: Put each stone in a separate, labeled bag. Write down any information you have about each stone, like where it came from.
5. Fill out forms: The lab will give you forms to fill out. Write down all the details they ask for. Be honest about what you know about the stones.
6. Send or bring the stones: Either mail your stones to the lab or bring them in person, following the lab's instructions. Make sure to pack them safely.
7. Wait for results: The lab will test your stones and send you a report. This can take a few days to a few weeks, depending on the lab and the tests needed.
What You Need to Do
- Take clear photos of your rough gemstones before sending them
- Insure your package if you're mailing the stones
- Keep all receipts and tracking numbers
- Be patient while waiting for results
- Make sure sellers are honest about their gems
- Ask questions if you don't understand something in the report
The Gem Certification Process
Understanding how gems are certified can help you appreciate the work gem labs do. Here's a simple breakdown of the process:
1. Registration: When a gem arrives at the lab, it's given a unique number. This number is used to track the gem through all tests.
2. Initial Examination: Experts look at the gem closely. They note its color, shape, and any visible features.
3. Weight and Measurements: The gem is carefully weighed and measured.
4. Advanced Testing: Labs use special tools to test the gem.
These might include:
Microscopes to look inside the gem
Spectrometers to study how the gem interacts with light
X-ray machines to see the gem's inner structure
5. Treatment Detection: Labs check if the gem has been treated to improve its appearance. Common treatments include heating and filling cracks with glass.
6. Origin Determination: Some labs try to figure out where the gem came from. This is done by studying tiny bits inside the gem called inclusions.
7. Grading: For some gems, like diamonds, labs give grades for things like color and clarity.
8. Report Creation: All the information is put into a report. This report describes the gem and gives the lab's opinion on whether it's natural, treated, or synthetic.
9. Final Check: Before the report is issued, another expert checks all the work to make sure it's correct.
This process can take anywhere from a few days to several weeks, depending on the gem and the tests needed.
