Recognise the two-part fastening
A toggle clasp commonly uses a bar that passes through an opening and then sits across it. The shape may form part of the visible design rather than disappearing beneath the wrist. For gold bracelets, ask to see both components and their intended closed relationship. A circular motif near a chain end is not enough to identify the fastening.
Check the complete fitting sequence
A demonstration should show the actual bracelet being put on and the bar returned to its normal resting position. Notice whether the wearer has enough room to operate it as instructed. The circumference that looks attractive once fastened and the clearance needed while fastening are related questions, but they are not the same measurement.
Avoid a universal security rule
A larger bar or smaller opening should not be treated as a guarantee about the complete bracelet. The proportions, connectors and fit must be assessed together. Ask the maker how closure should be checked in ordinary use and whether any additional component is supplied. Do not test the design by pulling it forcefully or substituting another bar that happens to pass through.
Confirm the intended combination
If the bracelet is to be shortened or lengthened, discuss how that change could affect the fastening sequence before approving work. Keep questions about fit tied to the selected design. When exploring CIELA bracelets, read the actual clasp description; this explanation of toggles does not imply that every chain bracelet uses one or that a standard length suits every wrist.
