The art of
restraint,
cast in gold.
Star Gold Refining is a discreet international house for the refining, assaying, and minting of precious metals — quietly entrusted by collectors, institutions, and family offices the world over.
A house measured in grams, judged in generations.
We do not advertise. We do not chase volume. We refine the metals of those who arrive by introduction — collectors, family offices, jewellery maisons, and the institutions that hold the world's bullion.
Every commission is conducted under our own roof, by our own hands, with the same patience the work has demanded since alchemists first chased the colour of the sun. Discretion is not a feature. It is the floor on which everything else is built.
Precision in four chapters.
Discretion
A confidential intake, a private vault, a settlement seen only by you and us. Anonymity is part of the service.
Refining
Aqua regia, electrolytic, and Miller chlorination — practised by hand, perfected over decades, delivered to four-nines purity.
Assaying
Fire assay, gravimetric analysis, ICP-MS. Three independent techniques, one indisputable result on every batch.
Minting
From a single commemorative medallion to a private bullion series — designed, alloyed, struck, and packaged in-house.
From rough material to four-nines fineness.
Doré, scrap, jewellery, granules, sweeps — every form arrives differently and leaves the same way: refined to investment grade and certified beyond dispute.
- Gold to 999.9 fineness
- Silver, platinum & palladium
- Aqua regia stone recovery
- Lossless sweeps & burnables
The numbers beneath the shine.
Fire assay. Gravimetric analysis. ICP-MS to the part per million. Three independent techniques on every batch — because a single answer should be unanswerable.
The Method
Six expressions. One standard.
