A figure 8 safety clasp is a small secondary component, shaped like the numeral 8, attached to a primary clasp to prevent accidental opening. It creates a second point of resistance that requires deliberate disengagement before the main closure can release.
Origin Story
If you are comparing emeralds by origin, the key sources outside Colombia are Zambia, whose stones read slightly bluer and cooler, Afghanistan's Panjshir Valley, Brazil, Zimbabwe, and Ethiopia, each producing material with color and inclusion characteristics distinct enough to affect value and preference.
Made With Purpose
Push button clasps appear most often on chain bracelets, tennis bracelets, and heavier link necklaces because these formats need secure closure and practical single-hand operation.
