Help! My Stone Fell Out. Why You Must Never Use Superglue

If your projection stone has dislodged, do not use Superglue (Cyanoacrylate). As Superglue cures, it releases fumes that settle on the lens surface, creating a permanent, frosted white fog known as "blooming" or "crazing." This chemical reaction is irreversible and destroys the micro-carved image. Instead, secure the stone in a zip-lock bag and contact us for a professional repair using optical-grade epoxy.

Don't Panic. We Can Save It (If You Don't Glue It).

I know the feeling. You look down at your chest, expecting to see that familiar sparkle, and instead, you see an empty metal setting. Your stomach drops. You scan the floor, frantic, until you find the tiny 5A Zirconia lens sitting on the carpet.

Your first instinct is to fix it immediately. You probably have a tube of Superglue or Krazy Glue in the kitchen drawer. It seems like the obvious solution—just a tiny dot, right?

Please, as someone who has wept over ruined necklaces with clients in our Sydney studio, put the glue away.

The stone itself is likely fine. The metal setting is likely fine. But if you introduce Superglue to the equation, you turn a simple repair into a tragedy. Superglue is chemically aggressive. It "off-gasses," meaning it releases vapour that coats nearby surfaces in a white, frosty residue. On a projection lens, this frost acts like a cataract, blinding the image forever.

Let’s handle this the right way, so your memory stays clear.

The "Emergency Protocol": A Step-by-Step Guide

If the worst happens, follow these steps exactly to ensure your piece can be rescued.

Step 1: Secure the Stone (The "Ziploc" Rule)

The Action: Find the stone and immediately place it in a small plastic bag (a sandwich bag or a jewellery pouch).

The Detail: Do not try to push the stone back into the setting "just for now." If the prongs are loose, it will fall out again, and next time you might not find it. Keep the stone and the necklace separate but together in the same bag.

Step 2: Inspect the "Claws"

The Action: Look closely at the empty metal setting on the necklace.

The Detail: Can you see the tiny metal prongs (claws)? Is one of them bent backwards or snapped off? This helps us diagnose why it happened. Often, a prong gets caught on a knitted jumper or a towel, pulling it open just enough for the stone to slip free. Take a clear photo of the empty setting.

Step 3: The "No-Touch" Transport

The Action: Contact our PhilU support team immediately.

The Detail: We will arrange a repair. Do not wrap the stone in tissue paper; it’s too easy to throw away by accident. Stick to the plastic bag. When you send it to us, we use a specific Optical Epoxy that has the same refractive index as the stone, ensuring light passes through without distortion.

Repair Guide: What to Avoid (The "Don'ts" List)

I see many DIY attempts that end in heartbreak. Here is your cheat sheet on what is safe and what is fatal for projection jewellery.

Action (Repair Method)	Safe?	Expert Note
Superglue (Cyanoacrylate)	❌ FATAL	Causes "blooming" (white fog) that ruins the image permanently.
Clear Nail Polish	❌ NO	It yellows over time and peels, creating a blurry projection.
Squeezing Prongs with Pliers	⚠️ Risky	Without the right tools, you can crush the stone or snap the metal claw off entirely.
Double-Sided Tape	❌ NO	It creates a gap behind the lens, shifting the focal point and blurring the photo.
Professional Optical Epoxy	✅ YES	The only safe adhesive. It cures clear and is water-resistant.

How to Capture the Perfect Projection (Once Fixed)

While your necklace is being repaired, you might want to plan your "Welcome Back" video for TikTok. Here is how to get that crisp, viral-worthy shot once your piece is returned to you, sparkling and secure.

1. The "Contrast" Backdrop

Don't project onto a patterned wall or your hand (skin texture interferes with the image).

The Tip: Use a plain white sheet of paper or a matte white wall. The high contrast makes the Nano-Carving pop.

2. The Lighting "Bullseye"

The Tip: Turn off the room lights. Use your phone’s flashlight. Hold the flat back of the pendant directly against the light source.

The Technique: Don't just hold it near the light. Touch the stone to the glass of the flash. Move it slowly until the circle of light on the wall is perfectly round—that’s your optical axis aligned.

3. The Camera Lock

Your phone hates focusing in the dark.

The Tip: Point your camera at the wall. Tap and hold the screen where the projection is to lock the focus (AE/AF Lock). Then start recording. This prevents the camera from "hunting" for focus and blurring your beautiful video.

The PhilU Quality Promise

It is rare for a stone to fall out. We use 4-prong or bezel settings designed to hold our lenses securely. However, jewellery is delicate, and life is busy. Accidents happen.

But here is the good news: A fallen stone is not a broken memory. It is just a loose part. As long as the lens is clean and the image is intact, we can reset it. We align the optical axis in our Sydney lab to ensure the picture is perfectly straight (no upside-down heads!) and secure it with UV-cured optical adhesive.

So please, throw away the Superglue. Send it home to us, and we will make it whole again.
