Two disciplines, one standard
From the ground beneath you to the stone in your hand.
For 29 years, Haldor Gems & Geosciences has united two disciplines under one roof — the trade of certified gemstones and the rigorous reading of the earth.

See our standard →Why clients stay
The same four commitments since 1997
Independent grading
Colour, clarity, cut and carat assessed by a qualified gemologist, never by salesmanship.
Full documentation
Every stone leaves with a certificate stating measurements, grade and any treatment observed.
Stated provenance
Origin stated where verifiable, and clearly marked where it is not.
Unbroken custody
Sealed parcels, logged handling, witnessed weighing, from our vault to your counter.
