Blue topaz is the traditional gemstone gift for the 4th wedding anniversary, and imperial topaz for the 23rd. The different color characters and rarity levels gives the selection actual meaning for the occasion.
Built For Ease
The figure 8 safety clasp asks one thing of the wearer: unhook the loop before opening the primary clasp. Nothing else. The security benefit, a second independent resistance point against accidental release, is real. The complexity added to the wearing experience is one finger action.
Visually Speaking
The flat housing surface of a box clasp lends itself to decorative work. Whether it be engraving, stone setting, or milgrain edging, the result is a closure that contributes to the piece's overall composition rather than just simply finishing it.
