Authenticity & Certification Guarantee

At Lía Gems & Jewellery, trust, transparency, and mineralogical accuracy are our highest priorities. We guarantee the natural origin and accurate representation of every stone we offer.

1

Independent Laboratory Testing

Every premium gemstone priced above $1,000 USD is sold accompanied by an official, independent gemological report/certificate from highly reputable laboratories, such as:

  • National Gem & Jewellery Authority (NGJA) — Sri Lanka
  • Gemological Institute of Colombo (GIC)
  • Gem Research Swisslab (GRS) / Alternative International Labs (where applicable)

The specific certificate number and lab origin are explicitly listed on each item's specification page and verified within our database.

Enhancement & Treatment Disclosure

We uphold a zero-tolerance policy for undisclosed gemstone treatments. The exact treatment status ("Heated" or "Unheated / Natural") is clearly documented for every stone.

  • Heated: Traditional thermal enhancement practiced globally to improve color and clarity.
  • Unheated: Rare, completely natural stones with zero human-induced enhancements.
