Blue topaz for the 4th anniversary, and imperial topaz at the 23rd, gives the variety choice meaning beyond color preference and connects the piece to the specific occasion with more precision than a single designation allows.
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.
Visually Speaking
Correct bail placement controls the finished angle. A centered single bail helps the pendant hang straight; an offset one creates a tilt that can make asymmetrical pieces feel intentional.
