Stage 2 of 5 · Prove
We test our own gold in our own laboratory, against international standards, with documented methodology. Every bar that leaves us carries a certificate signed by our chief metallurgist. Buyers who require independent verification can have any sample re-tested by a third party of their choosing.

— How it works
Assay, in four steps.
- 01
Sampling.
Doré is sampled using methods aligned with LBMA technical guidance. Samples are taken from multiple points to ensure homogeneity.
- 02
Fire assay.
The reference method. Gold content determined by cupellation, weighed to four decimal places.
- 03
ICP verification.
Samples are cross-checked using inductively coupled plasma spectroscopy for trace elements and confirmation.
- 04
Certification.
Results are recorded, signed, and stored. A printed and digital certificate accompanies every bar.
