Vindicta's 925 Silver
Solid, not plated
Every Vindicta piece is hallmarked solid 925 silver — 92.5% pure silver. Unlike plated jewelry, it won't chip or peel and keeps its shine for years.
Built to last
Solid silver is a real investment: it can be passed down, repaired, and develops a unique patina over time — the opposite of disposable jewelry.
Care
Avoid prolonged contact with water and oils. Regular gentle cleaning is enough to preserve its shine for years to come.
Lifetime guarantee
We guarantee the purity of our 925 silver for life: 92.5% solid silver, hallmarked, a composition that will never change. (Regular care preserves surface shine — see our care tips.)
