Personalised Photo Necklaces | Custom Picture Pendants & Memory Keepsakes

The Definition: Optical Projection vs. Resin Encapsulation

In the domain of sentimental jewellery, a photo necklace is defined as a wearable pendant designed to retain and display a specific photographic image. Structurally, these are categorized into two distinct technological lineages: Optical Projection and Resin Encapsulation.

Optical Projection utilises a hemispherical convex lens (usually synthetic corundum or high-clarity glass). A micro-photograph, often just 3mm in diameter, is etched onto a transparency film using lithographic technology and mounted at the lens's focal point. By applying light through the rear of the stone, the image is refracted and magnified onto a surface. For a deeper technical analysis of this physics, we recommend reading our comprehensive guide on the definition and optical mechanics of projection jewellery. For those ready to purchase, we recommend examining our specialised collection of photo projection necklaces with micro-lens technology.

Resin Encapsulation involves placing a high-resolution photo print into a bezel setting. A clear, liquid epoxy resin is poured over the image, which cures to form a hard, dome-shaped shield. This process, known as "doming," creates a magnifying effect and a hermetic seal against moisture. Traditionalists may prefer mechanical enclosures; for this, our classic range of personalised photo locket necklaces relies on hinge mechanics rather than chemical bonding.

Material Science: Metallurgy and UV Stability

The longevity of a memory necklace is dictated by the interaction between the metal substrate and the photo medium. At IfShe, we prioritise 925 Sterling Silver for its superior mechanical properties.

• Silver Alloy Composition: We use an alloy of 92.5% silver and 7.5% copper. Pure silver (Ag 99.9%) is too malleable (soft) for the prongs required to hold a projection stone or the bezel walls needed for resin. The copper addition increases the tensile strength and Vickers hardness, ensuring structural integrity under daily wear.
• Plating & Oxidation: To prevent the copper content from reacting with skin sulphides (tarnishing), our pieces are plated with Rhodium or 18k Gold. This plating must be at least 2.5 microns thick (Vermeil standard) to resist abrasion.
• UV Stabilisation: Photographs are susceptible to photodegradation from ultraviolet light. Our printing process utilises archival-grade inks and UV-blocking resins to prevent the cyan, magenta, and yellow dyes from breaking down, ensuring the image retains its colour fidelity for decades.

Occasions & Etiquette: The Semantics of Memory Gifts

The emotional intent behind a photo necklace shifts the "Entity" from a simple accessory to a "Transition Object" in psychological terms.

• Memorial & Grief: For those experiencing loss, a necklace containing the image of a departed loved one or pet serves as a tangible anchor. In these instances, the durability of the image is paramount.
• Romantic Milestones: For anniversaries or Valentine's Day, projection jewellery offers a "hidden secret" dynamic. It is an intimate gift where the image is private to the wearer. If a necklace is not the preferred style, many couples opt to browse our alternative selection of photo projection bracelets which utilise the same lens technology.
• Matriarchal Gifting: For Mother’s Day, a collage or multi-charm piece allows for the representation of the entire family unit (The "Family Tree" entity).

Care Guide: Preventing Hydrolysis and Abrasion

Scientific maintenance is required to preserve the optical clarity of the photo element.

• Avoid Hydrolysis: Resin and glass settings can be susceptible to hot water. Prolonged exposure to hot showers can cause hydrolysis, where water molecules disrupt the chemical bonds of the glue or resin, leading to cloudiness (fogging) over the image.
• Chemical Reactivity: Perfumes and lotions often contain alcohol or chlorinated compounds. These can react with the epoxy resin, causing it to yellow (ambering) over time. Always apply cosmetics before putting on the jewellery.
• Mechanical Cleaning: Do not use ultrasonic cleaners for any items within our photo jewellery range. The high-frequency vibrations can delaminate the photo print from the glass or resin. Use a soft microfibre cloth for polishing.

Frequently Asked Questions

• What is the difference between a locket and a photo necklace?

  Structurally, a locket is a mechanical container with a hinge that opens to reveal a loose or glued photograph inside. A photo necklace (specifically projection or resin types) integrates the image permanently into the structure of the pendant, either by sealing it under a protective layer or embedding it within a gemstone lens, making the image a fixed structural element.

• Will the picture inside the necklace fade?

  We mitigate fading through Archival Science. By using UV-resistant encapsulation materials and hermetically sealing the image against oxygen, we prevent the oxidation of the ink pigments. However, we recommend storing the jewellery away from direct sunlight when not in use to maximise its lifespan.

• How do I view the image in a projection necklace?

  The image is viewed via Light Refraction. You can hold the pendant's convex lens close to one eye to see the magnified image directly. Alternatively, shining a high-lumen light source (like a phone torch) through the flat back of the stone will project the image onto a wall, though this requires a dark environment for optimal contrast.
