Locket identity and boundaries Establishes the combination of wearable ornament and keepsake enclosure that identifies a locket.
Keepsake enclosure
Examines evidence that the ornament was designed to enclose an image or keepsake.
Intentional content space
Record the compartment and evidence of its intended role, separating observed construction from an inferred use.
- What compartment, insert frame or other construction indicates that this ornament was intended to enclose a keepsake? definition
- What distinguishes its intended function from that of a watch case, pill container or decorative hollow pendant? boundary
Wearable form and completeness
Identifies the wearing arrangement and recognises missing parts or later conversions.
Original and current form
Record how the locket is worn and whether missing or altered features obscure its original identity.
- Which features establish whether the locket is a pendant, brooch, bracelet component or another wearable form? definition
- What evidence supports any claim that a lid, bail, pin or compartment was removed, replaced or added later? provenance
Compartment access and retention Describes how the enclosure opens, holds its contents and closes.
Opening and closure
Identifies the intended access method and the condition of moving or mating parts.
Controlled compartment access
Record the opening mechanism, operating condition and evidence needed before attempting access.
- Where is the intended opening point, and what motion releases the cover without forcing the body or hinge? action
- Does the closure engage securely, and is there distortion, binding or looseness that limits opening or wear? measurement
Insert fit and retainers
Assesses available space and the means of keeping contents in position.
Usable keepsake capacity
Record usable compartment dimensions and retainer constraints rather than inferring capacity from external size.
- What are the usable dimensions of each compartment after accounting for its frame, glazing and closure clearance? measurement
- Can the proposed insert be fitted or removed without disturbing a retainer, existing contents or an adhesive bond? action
Keepsake association and permissions Connects the locket to its contents, commemorative associations and permitted access.
Contents and association
Separates observed contents from claims about their origin or meaning.
Documented content relationship
Record what is enclosed and the evidence connecting it to the locket or a commemorated person.
- What contents are directly observed, and what remains unknown because the compartment has not been opened? definition
- What evidence supports the identity, date or association of each keepsake, including whether it is original to this locket? provenance
Viewing and content changes
Establishes constraints on exposing, recording or replacing enclosed material.
Permitted keepsake handling
Record any access restrictions and the authority for changing the arrangement of contents.
- What permission or restriction governs opening the locket and viewing or photographing its contents? action
- May its contents be removed or replaced, and what record must preserve their previous arrangement and association? action
Wear and preservation Assesses attachment reliability and preservation needs of the enclosure together with its contents.
Suspension and loss risk
Examines the features connecting the locket to its carrier or clothing.
Wearing attachment integrity
Record wear, deformation and compatibility at the locket's attachment points.
- What wear, cracking or deformation is visible in the bail, attachment loop, brooch pin or integral mounting? measurement
- Can the intended chain, bracelet or clothing attachment support this locket without obstructing its closure or stressing its fittings? action
Enclosure and content preservation
Considers treatment and storage constraints across the locket's material interfaces.
Compatible care
Record materials, deterioration and uncertainties that determine an appropriate care method.
- Which body, lining, glazing or content materials are identified, and where are staining, corrosion, cracking or trapped moisture observed? measurement
- What evidence supports a cleaning or storage method that will preserve both the enclosure and its contents? action
- Which condition issues require specialist assessment before the locket is opened, cleaned or worn? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
Reported evidence
Findings from the breadth pass, kept separate from the structural claims.

What it is Filled
A locket is a small wearable ornamental case, typically suspended as a pendant, that opens to hold a portrait, hair, or another personal keepsake.
In scope
- Identity as an ornament designed to enclose a small image or keepsake
- Body, compartment geometry and access mechanism
- Closure, hinges and content-retention features where present
- Integral suspension or wearable attachment features
- Relationship to enclosed contents and associated handling permissions
- Condition affecting wear, opening and preservation
Out of scope
- Necklaces, chains and bracelets as independently modelled carriers
- Photographs, hair, inscriptions and other keepsakes as independent informational or material objects
- General jewellery manufacturing and repair processes
- People and relationships commemorated by the locket
- Ownership, inheritance and sale transactions
- Standalone reliquaries, pill containers and watches whose identity is not that of a locket
Why it exists Filled
Enable an agent to recognise a locket, assess its enclosure and contents, and decide how it may be worn, opened, preserved or transferred.
Distinguishing features Filled
- Has an intentional enclosure for a small image or keepsake; a solid pendant or an ornament with only a decorative recess does not establish this identity.
- Is intended as a wearable ornament; a freestanding miniature picture case requires a different primary classification.
- Has, or originally had, a means of inserting or enclosing contents; a missing lid or broken hinge may indicate an incomplete locket rather than a different object kind.
- Contains a compartment whose keepsake function distinguishes it from an otherwise similar watch case or purpose-built pill container.
- May also be a pendant, brooch or bracelet component: those terms identify its wearing arrangement and do not exclude locket identity.
What robots and AI may and may not do Filled
Must not
- Open, copy or share the portrait, hair or keepsake inside someone else's locket without permission.
- Sell plated or base-metal lockets as solid gold or silver.
- Treat mourning lockets holding human hair or remains as ordinary stock without disclosure.
Only with a human decision
- Deciding what to do with a locket's contents, such as hair or photographs, after its owner dies.
May
- Describe lockets and their history as keepsakes and mourning jewellery.
- Catalogue, value or repair a locket for its owner.
Moral aspects Filled
- Lockets hold private memories of loved ones, sometimes their remains.
- Small parts and cheap metals can harm children who wear them.
Who is affected
- Owners and their families
- Children who wear jewellery
- Buyers
Owners Filled
Steward
The person who owns and wears it.

- Where should the catalogue draw the boundary between wearable reliquaries and lockets when their construction overlaps?
- Which documented construction traditions require access or retention categories beyond the provisional categories listed here?
- Which conservation sources establish appropriate care for lockets combining metal, photographic material, hair, glazing and adhesives?
- Does an existing Vercy jewellery or pendant model already own shared attachment and material characteristics that this model should reference?
