92.5% pure silver alloyed with 7.5% copper for strength and workability. Hallmarked, SGS testable, lead-free, and nickel-free on every Bali Silver Export piece.
925 sterling silver is an alloy containing 92.5% pure silver and 7.5% other metals — typically copper — which provides the strength and durability necessary for everyday wearable jewelry.
925 sterling silver has been the international standard for sterling silver since the 14th century. The 925 designation indicates 92.5% pure silver content (the maximum practical purity for jewelry that resists deformation in everyday wear) and 7.5% copper, which gives the alloy its strength and characteristic warm sheen.
The copper ratio in sterling silver is a precise balance: too much copper darkens the alloy and increases tarnishing; too little leaves the metal too soft to hold detail or withstand wear.
At Bali Silver Export every piece is verified at 92.5% silver content via spectroscopic analysis before production, with random batch testing throughout. Lead, nickel, and cadmium are excluded from every alloy — making our silver hypoallergenic and compliant with EU REACH, US CPSIA, and Japanese JIS standards.
We verify silver content through four independent methods:
Bali sterling silver uses the same 92.5% purity standard as all sterling silver worldwide. What distinguishes Bali silver is the craftsmanship applied to the material — the centuries-old hand techniques (filigree, granulation, oxidation) practiced in Celuk Village, and the documented quality assurance that accompanies every wholesale shipment.
For wholesale buyers and OEM partners, we provide third-party SGS laboratory assay certificates on request. Confirmed within 48 hours.
