925 + 18K Necklaces

925-18k means a necklace constructed using both 925 sterling silver and 18k gold, with each metal contributing to specific elements. The 925 component is sterling silver at 92.5% purity; the 18k component is gold at 75% purity. The 18k gold provides the richest standard fine jewelry gold color in the accent sections, while the sterling silver forms the main chain body at a lower material cost than full 18k construction.

925-18k necklaces are practical for daily wear. The sterling silver component tarnishes with air and moisture exposure; the 18k gold component does not. Necklaces tarnish more slowly than bracelets or anklets because they experience lower moisture contact. Anti-tarnish storage when not worn extends both metal components.

The premium richness of 18K gold in both the chain and pendant creates the most elevated mixed-metal pendant combination.
