Trusted Certification - Every Gemstone, Authenticated.
At Oblyvia, authenticity is never optional.
All our gemstones are certified by internationally recognized gemological laboratories — ensuring full traceability, integrity, and long-term value.
Certification is more than paperwork — it’s your assurance of quality, origin, and ethical sourcing.
Our certificates provide detailed analysis of each gem’s:
- Type & species
- Carat weight & dimensions
- Color & clarity grade
- Cut quality
- Origin (when determinable)
- Any treatments or enhancements
This ensures transparency, protects your investment, and supports ethical practices.
