Bail design matters because it is the pendant's attachment architecture. In a single bail pendant, the junction between object and wearer reveals how completely the maker considered the piece.
Style Notes
A layering-width bail opening is physically distinct from a standard one. It's wide enough that two chains can pass through with clearance rather than friction, and the interior dimension should be sufficient to allow both chains to move independently rather than straining against each other and the fitting walls when the necklaces are adjusted or moved.
Industry Insight
The Kimberley Process was adopted in 2003 and requires participating countries to certify that rough diamond exports originate from conflict-free sources and establishes minimum standards for chain-of-custody documentation from mine to export. It currently covers the majority of the world's rough diamond trade by volume.
