For those who react to base metals, gold over sterling silver is worth considering: the gold surface is what contacts skin, and genuine gold is well-tolerated by most people with metal sensitivity.
Built For Ease
Among the practical virtues that have kept the lobster clasp in continuous use, ease of self-fastening is near the top of the list. The lever mechanism and compact form make it one of the more manageable closures for a single hand working alone.
Made With Purpose
Structural strength in sterling silver comes directly from its alloy composition. The copper content that defines the 925 standard is what allows jewelers to achieve precise forms, fine details, and settings that maintain their shape through regular wear in a way pure silver cannot.
