Gemstone Certification & Authentication

At Tili Gems by Vivid Minerals, transparency and trust are the foundation of everything we do. While we're confident in our gemstone descriptions and expertise, we believe you shouldn't have to take our word alone. That's why we prioritize independent third-party certification for our collection.


Our Certification Commitment

More than 80% of our gemstones come with certificates from internationally recognized gemological laboratories. This isn't just good practice; it's our commitment to protecting your investment and ensuring complete confidence in your purchase.

We Cover All Certification Costs

Gemstone certification represents a significant investment. We spend over one hundred thousand dollars annually on professional certifications because your peace of mind is worth it. This cost is absorbed entirely by our company and never passed on to you.

We believe we're the only gemstone retailer that takes full responsibility for mandatory certification across our collection, reinforcing our commitment to transparency and customer protection.

We collaborate exclusively with the world's most respected gemological laboratories, including:

  • GIA (Gemological Institute of America)
  • GRS (Gem Research Swisslab)
  • SSEF (Swiss Gemmological Institute)
  • Gübelin Gem Lab
  • GIT (Gem and Jewelry Institute of Thailand)
  • AIGS (Asian Institute of Gemological Sciences)

Understanding Our Inventory

Certified Gemstones:
All high-value gemstones in our collection come with certificates, and many have multiple certifications from different laboratories for additional verification.

Gemstones Pending Certification:
A small percentage of our lower-priced gemstones may not yet have certificates at the time they're listed on our website. This occurs because we source and cut gemstones in substantial quantities, and the certification process takes time.

Your Protection:
If you're interested in a gemstone that doesn't currently have a certificate, simply contact us. We'll arrange for certification at our expense before your purchase is finalized.


Our Recommendation

We strongly encourage you not to purchase gemstones without prior certification, whether from us or any other retailer.

Independent certification provides:

  • Verification of gemstone species and variety
  • Confirmation of natural origin
  • Documentation of any treatments or enhancements
  • Professional assessment of quality characteristics
  • Protection for your investment
  • Peace of mind
