Luna Time Capsule Ring | MED

Inspired by historical reliquaries, Time Capsule Keepsakes hold your inclusions in their natural form within a dry, fully sealed waterproof compartment beneath a hand-cut genuine crystal.

Each Time Capsule is entirely handcrafted in Sydney and cast in solid, nickel-free precious metal, making this our most durable keepsake collection.

Suitable for breastmilk, ashes, hair, umbilical cord, fabric, flowers and other sentimental inclusions. Slight movement may occur as inclusions are not permanently fixed in place.

STEP 1: Choose your Style

Start by selecting your precious metal and chain style or ring size.

STEP 2: Select your Main Inclusion

Choose the main inclusion you would like featured inside your Time Capsule. Depending on the inclusion selected, it can either fill the compartment or be placed over a coloured base.

STEP 3: Add Additional Inclusions - Optional

You can add additional inclusions to be arranged within your Time Capsule. These will be carefully placed over or within your main inclusion, depending on the materials selected.

Your inclusions are preserved in their natural form within a dry, waterproof compartment. While they are arranged with secure placement in mind, some inclusions may shift slightly over time as the piece is worn.

STEP 4: Select your Crystal Window Style

Choose the crystal window that will seal and protect your inclusions within the compartment. Select from Crystal Quartz in Smooth or Faceted finishes, or Rose Cut Moissanite (SML / MED sizes).

STEP 5: Engraving - Optional

For rings, engraving is placed on the inside of the band and can include up to 16 characters.

For pendants, engraving options depend on the size selected:

• SML - 1 line, 6 characters
• MED - 2 lines, 6 characters per line
• LRG - 3 lines, 6 characters per line

STEP 6: Share Your Story - Optional

If you’d like to, you can share the story behind your keepsake and what it means to you.

Your Time Capsule is entirely handcrafted using the lost-wax casting method and made from recycled, 100% Australian gold or nickel-free metals.
Each piece is created as a lasting heirloom, designed to be passed down through generations.

Made with 37.5% pure gold for added strength and durability. Available in Yellow Gold, Rose Gold and Palladium White Gold.

14k Gold
Made with 58.5% pure gold for a richer finish and greater heirloom value. Available in Yellow Gold, Rose Gold and Palladium White Gold.

Palladium White Gold has a natural white tone and does not require rhodium plating.

Our standard turnaround time is 8–10 weeks from the date we receive your inclusions. During peak periods, including Mother’s Day and Christmas, processing times may be slightly longer.

You’ll receive updates throughout the creation process, so you always know how your keepsake is progressing.

Your Time Capsule 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 Time Capsule 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.

Arrangements with breastmilk or coloured backgrounds use our non-yellowing cold enamel and are covered under our non-yellow warranty.


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.
