The Eternity Necklace is a handcrafted sterling silver cremation necklace designed to keep the memory of a loved one close in a subtle, elegant way. At the center of the pendant rests a hand-formed memorial glass marble infused with cremation ashes, creating soft swirling patterns and shimmer unique to every piece.

This cremation jewelry design features an infinity-inspired sterling silver setting that gently wraps around the memorial marble, symbolizing enduring love and connection. Lightweight and comfortable for everyday wear, the Eternity Necklace blends meaningful remembrance with timeless style, making it a beautiful choice for both human memorial jewelry and pet memorial jewelry.

Each memorial pendant is individually handcrafted in our Arizona studio by husband-and-wife artisans using traditional flame-working techniques. Because every cremation glass marble is made by hand, no two necklaces will ever be exactly alike.

5. Completed & Shipped Back to You

Polished vs Antiqued Finishes

Two green cremation marble pendants with silver chains on a white background, labeled 'Polished' and 'Antiqued'.

Our polished finish is bright, reflective, and clean with a smooth silver appearance. Details remain silver for a crisp, luminous look.

Our antiqued finish has a softer brushed patina with darker tones worked into the details for a more vintage-inspired appearance.

Because each piece is handmade and finished individually, slight variations in texture and patina are normal and part of what makes every memorial unique.

Important Ordering Details

Because each piece is handmade to order using the materials you provide, we’re unable to accept returns or cancellations once production has begun.

That said, we stand behind our work. If there are any issues with your order, please reach out—we’ll always do our best to make it right.

If you need to make changes to your order, contact us as soon as possible and we’ll do our best to accommodate before production begins.

Why Choose Us?

We’re a small husband-and-wife team creating each memorial by hand in our Arizona studio. This isn’t mass production—every piece is made one at a time, with care, intention, and respect.

Handcrafted, Not Mass Produced
Each memorial is individually flame-worked and finished by hand. No shortcuts, no assembly-line production.

Respectful Handling
Your loved one’s ashes are carefully tracked and handled throughout the entire process. We treat every order with the same care we would give our own family.

Built to Last
We use solid sterling silver and 14k yellow gold, permanently fusing the ashes within durable borosilicate glass. No temporary settings — just heirloom-quality craftsmanship designed to last for generations.

Clear, Honest Process
We keep you informed along the way and are always available if questions come up. If anything ever needs attention, we’ll work with you directly to make it right.

Every piece we create carries a story. We’re honored to be part of preserving it.

Care Instructions

Your memorial bead is made from durable borosilicate glass with the ashes permanently sealed inside, making it safe for everyday wear, including exposure to water. Unlike resin-based alternatives, the glass will not yellow or cloud over time.

Sterling silver components will naturally tarnish over time. To keep your piece looking its best, we recommend:

  • Removing before swimming in pools or hot tubs
  • Avoiding contact with harsh chemicals or cleaners
  • Storing in a dry place when not in use
  • Using the included polishing cloth as needed

With proper care, your memorial will remain a lasting and meaningful keepsake for years to come.
