Silver Purity Guide
Know Exactly What You Wear
Knowledge is the greatest safeguard when investing in fine metals. Learn what makes 925 sterling silver the international benchmark for jewelry excellence.
92.5% Pure Silver + 7.5% Noble Strength
Pure fine silver (99.9%) is as soft as putty — rings would bend under a handshake. Adding 7.5% copper preserves silver’s precious value while imparting structural resilience.

How to Verify Hallmarks on Your Jewelry

3 Quick At-Home Verification Tests
Test 1: The Strong Magnet Test
Real silver is diamagnetic — meaning it is not attracted to magnets. Place a strong household neodymium magnet near your jewelry. If it snaps aggressively to the magnet, it contains iron or cheap ferrous base metals and is not genuine sterling silver.
Test 2: The Ice Cube Melt Test
Silver possesses the highest thermal conductivity of any known metal on Earth. Place an ice cube directly onto a flat piece of silver jewelry. The ice will begin melting immediately, almost as if placed on a hot skillet, because silver conducts room-temperature heat instantaneously into the ice.
Test 3: The Skin Test (Hypoallergenic Check)
Base metal imitation jewelry contains nickel which oxidizes into copper salts or nickel allergens, leaving an unsightly greenish or black ring around your finger or neck after sweating. Pure 925 sterling silver is 100% skin safe and never turns skin green.
