Each Time Capsule Keepsake is handcrafted in Sydney, Australia, making your piece truly one of a kind. Variations in texture and subtle colour shifts may naturally occur during the handmade process. As your inclusions are preserved naturally within a dry compartment, they may shift or move over time. These unique details are part of your jewellery’s story, adding character, depth, and individuality to every piece.
How it works
STEP 1: Choose your Style
Start by selecting your precious metal and chain style or ring size.
STEP 2: Your Arrangement style & Main Inclusion
Select if you'd like a Pressed or Shaker style keepsake. This will determine how your inclusions sit within your Time Capsule.
Pressed: Your main inclusion will fill the compartment - additional inclusions will be pressed over the top of your main inclusion.
Shaker: Your main inclusion will be used to create a solid background - additional inclusions will be placed loosely and move freely within the compartment.
STEP 3: Add Additional Inclusions (Optional)
Your selected additional inclusions will be placed within your Time Capsule depending on your chosen Arrangement style:
Pressed: Additional inclusions will be pressed over the top of your main inclusion within the compartment. Your inclusions may shift slightly over time but will not move freely.
Shaker: Additional inclusions will be placed loosely and move freely within the compartment. Some materials may move more freely than others.
STEP 4: Select your Crystal Window style
This is the crystal that seals your inclusions within the compartment.
STEP 5: Engraving (Optional)
Add up to 6 characters for Pendants and up to 16 characters for selected Ring styles.
STEP 6: Share Your Story (Optional)
I'm honoured that you've chosen me to create your speical keepsake. Tell me about the journey that has brought you here and why this keepsake will mean so much to you.

We’ll keep you updated at every step of the creation process.
Reliquary care
Your Reliquary is made to be treasured for a lifetime, but like all fine jewellery, it needs care to keep it looking its best.
Caring for metals:
All jewellery made from precious metals will show signs of wear with everyday use. Light scratches, soft patina, or slight darkening over time are normal. To keep your Reliquary bright simply; wipe your piece regularly with a soft polishing cloth, avoid abrasive cleaners, and store it somewhere dry when not in use.
Waterproofing:
Each Reliquary has a permanent waterproof seal protecting your inclusions. It’s safe for everyday wear, but avoid chlorinated water and prolonged submergence. Treat it like a waterproof watch; fine for rain, handwashing and showers, but not for swimming, spas, or long periods underwater.
Chlorinated & salt water will corrode precious metals
Non-Yellowing:
Your inclusions sit inside a dry compartment, no resin is used.
Shaker arrangements with breastmilk or coloured backgrounds use our non-yellowing cold enamel and are covered under our non-yellow guarantee.
Avoid:
Chlorine, dyes, harsh chemicals, salt water, perfumes, lotions, self-tanners, and long periods of direct sunlight or heat. These elements can damage your Reliquary and/or Inclusions.
Storage:
Keep your piece dry and stored in a jewellery box or pouch, away from humidity to keep its shine and other jewellery to avoid scratches.

FAQ
Can I send frozen milk?
Yes you can!
If your milk is frozen please make sure you defrost it and mail it to us in a sterile milk storage bag.
Squeeze out any air inside the bag, seal it, wrap it in a paper towel and place it inside another milk storage bag. Label the second bag with your order number (not receipt number) and your name.
Your milk does not need to stay cold in transit.
Are Reliquaries waterproof?
Yes. Every Reliquary has a permanent waterproof seal that protects your inclusions inside a dry, enclosed compartment.
We recommend treating your piece like a waterproof watch, safe for handwashing, rain and showering but not for swimming, spas, or long periods underwater.
How many inclusions can I add to my Reliquary?
There’s no limit to how many inclusions you can add. The main thing to keep in mind is the size of your piece and the arrangement style you’ve chosen.
For Shaker Reliquaries, your main inclusion needs to be large enough to sit over the background of the compartment. Any additional inclusions will be added as small fragments. Some inclusions may move more freely than others once sealed, this is normal, and we can’t control their movement inside the compartment.
For hair placements, the Ringlet style requires at least 5cm (2") in length. If you’re sending multiple hair samples, we’ll either mix them or place them side by side depending on their lengths and the style selected (Natural or Ringlet).
If you’re unsure what will fit, you can always email us a photo of your inclusions before ordering. We’re happy to guide you toward the best option for your piece.
How much of my inclusions do I send?
Milk: 2-15mL (1 tbs) of milk inside a sterile milk storage bag with the air squeezed out.
Ashes: 1/2 teaspoon. Any ashes that aren't used for your piece are posted back to you with your completed jewellery.
Hair: A pinch about 5mm thick. If you'd like the ringlet placement, please ensure it's at least 5cm long.
Placenta/Umbilical cord: One capsule or a 5-10mm dried section.
Sand/soil: 1/2 teaspoon. Soil can not be sent overseas.
Flowers: 2-4 Petals from each flower. These must be dried for a minimum of 3 weeks and pest free prior to being sent to us.
