Gemstone certification from our in-house gemological lab
Trust is everything when you buy a gemstone. Safir operates its own gemological laboratory, so every stone we sell is independently identified, graded and documented: its species, natural or treated status, and where possible its geographic origin. We also certify stones you already own.

Colour, clarity, cut & carat
The 4Cs assessed and documented for coloured stones, calibrated to international standards.
Origin assessment
Geographic origin determination where the stone characteristics allow: Burmese, Ceylon, Colombian and more.
Certify your own gemstone
If you own a gemstone, whether inherited, purchased elsewhere, or previously uncertified, bring it to our Publika gallery. Our lab will assess and certify it: identity, natural status, treatment disclosure, and origin where determinable.
A certificate gives you documentation for insurance, a paper trail for resale, and the certainty of knowing precisely what you own. For a stone of any significance, it is not optional.
Book a certification appointmentWhy certification cannot be optional
You cannot reliably distinguish a natural gemstone from a synthetic, or an untreated stone from a treated one, by sight alone. Even experienced gemologists require laboratory equipment to be certain.
A gemological certificate is the only objective, third-party evidence of what you own. It protects you when buying, gives you documentation for insurance, and is essential for any future resale.
