Start with the inside opening
A locket's outside width and height describe its exterior, not necessarily the space available for a photograph. Borders, hinges, internal frames and the closure can occupy part of that outline. When comparing gold pendants that open, ask for the usable interior dimensions and the shape of the insert before preparing a photograph for the piece.
Check what holds the image
Ask whether the locket has an insert, retaining frame or other arrangement, and request the supplied instructions. A photograph that fits inside the outer edge may still cover an area that needs to remain clear. Do not force paper beneath an unfamiliar frame or assume that a removable-looking component is intended to be taken out by the wearer.
Prepare a reversible paper trial
Once the dimensions are confirmed, make a paper template outside the jewellery and test the crop against it. Keep the original photograph unchanged until the format is clear. Consider whether a face or important detail will be obscured by a border. This planning step can be useful even when the provider prepares the final image for you.
Confirm the actual design
Check whether an insert is included, whether image preparation is offered and which personalisation terms apply. Do not put liquid adhesive, a thick print or a protective layer inside without permission from the maker. Explore CIELA pendants by their stated construction; the presence of a closed decorative motif in a photograph does not establish that it opens or contains usable photo space.
