Tanzanite's combination of strong saturation, high refractive index, and trichroism that distinguishes it from other blue stones establish its viability for rings, pendants, and earrings across the fine jewelry market.
Built For Ease
Weakened spring tension in a box clasp is a standard repair. A jeweler can restore it by adjusting the tongue's curvature or replacing the housing, both operations routine enough to preserve the integrity of a fine piece.
Made With Purpose
The figure-8 safety is attached by solder or mechanical connection to one side of the primary clasp, making it captive. It moves with the clasp rather than independently, and its security function is always present rather than requiring the wearer to engage a separate element.
