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.

I received my necklace a few days ago and it is absolutely perfect! I Love it so much and it's such a beautiful way to honor my sweet pup that passed. I have him close to my heart forever. Patti has been amazing to deal with! I would highly recommend purchasing from LockedIn Art.

I am so pleased with my necklace.

I haven't taken if off since it arrived! The whole entire process went very smoothly from the time I placed my order until the necklace arrived. I was treated with such kindness after the loss of my mother. And the marble is just beautiful. Thank you!

After losing my sphynx cat to cancer, my heart was shattered.

I wanted something to remember him by and try to keep him close to my heart. I ordered an Eternity pendant in daffodil to remind me of his golden eyes. Anytime I am sad, I touch the bead and it brings me comfort. I love the style, quality, and above all else, the care and empathy I received during the process. I am extremely grateful for the kind, loving folks at Locked In Art for the service they provide to anyone who has lost a loved one - even those with 4 legs. Thank you so much!

Again, another wonderful piece of art.

I purchased this for my mother in law after the loss of my husband. It's a match time and will keep him close to both of us forever.

Wow! Beautiful doesn't even begin to describe this necklace! I got this for my mom who recently lost her beloved cavalier king charles. Every step from placing my order was handled with care, kindness, and professionalism. Patti was wonderful with communicating every step of the way as well as showing much empathy towards the loss of a sweet soul. When I got the final product I couldn't believe how perfect it was! I can't wait to see my mom's face when I give her a precious memorial of her precious friend.

Locked in Art is the most kind hearted, professional, warm and caring people. From the beginning of the process through the end they stayed in touch. They made the whole process so easy. I was worried that I would not be able to collect my babies ashes, but no worries, they provide the sweetest, most dignified little kit for that, and made the process as painless as possible, including mailing back to them. Highly recommend. They are a God send. I will have my babies around my neck and close to my heart for eternity. Thank you.

Very professional interaction during a difficult time. Extremely pleased with the final product. The packing materials and engraved storage box were much higher quality than I expected. I wear my necklace regularly, and can't think of a better way to honor my departed pet. Thanks so much for that opportunity.

I wish there were more than 5 stars....as this shop would get a 10. I ordered 2 necklaces in 2 different colors. Both pieces are beautiful. The friendliness and kindness you both show to your customers is truly amazing. The extra stones you sent, the cleaning cloth, as well as the engraved box is just amazing. Even the way everything was wrapped in the box just shows how much time and care you put in to making sure everything was perfect. Thank you from the bottom of my heart.
