Mithril Silver

Our custom Mithril silver looks better and lasts longer than sterling silver. Adding Germanium and increasing silver to 93.0% gives you stronger and more tarnish resistant jewelry with a brighter silver color.

We grew up on video games and Lord of the Rings, so Mithril was a clear naming choice.


Our sterling silver chains are Rhodium plated for added durability and tarnish resistance. Rhodium is rare and more expensive than gold!

18K Gold Vermeil
Our gold vermeil is 18k gold or 18k rose gold layered over our Mithril Silver.

We set all Mementum jewelry with a one-of-a-kind Digital Soul - a secret key that unlocks your memories in the free Mementum app.

Made from specialized Lanthanum glass, each custom Digital Soul undergoes a month long manufacturing process. In the final step, we inscribe a unique key into each Digital Soul with micron-level precision.

Why go through all this trouble?

We know what it’s like when someone makes you feel truly special - it’s our mission to help you make them feel the same way. So, we designed a keepsake meant to last generations, a stylish reminder that they are loved, no matter where life takes them. So we said no to electronics, NFC tags, and RFID chips in our jewelry.

  • Make sure you are in a room with ample lighting for the jewelry to scan properly
  • If it’s your first time, we recommend putting your phone on a flat surface
  • Locate the front of your Digital Soul (the front is curved, the back is flat)
  • Open the Mementum app and tap ‘Scan’
  • Touch and align the front of your Digital Soul to the front-facing camera of your phone (psst... if you don’t see the code, try flipping the jewelry!)

  • Once you load the memories onto the Digital Soul, the recipient can create their own app account, then scan it to find the memories. There’s no need to share an account.
  • Remove jewelry before showering, bathing, or swimming
  • Clean your jewelry occasionally with a soft cloth
  • Always put your jewelry on after you apply perfume, lotion or other body sprays
  • Store your jewelry in a cool, dark place

Yes, the Digital Soul of your jewelry is waterproof and will continue to function after showering. However, we strongly recommend not exposing your jewelry to any type of water because water can cause it to oxidize more quickly. To keep it beautiful and sparkling, remove it before showering.

so so beautiful!!

my husband loves it. What a wonderful and unique idea. He said, he will never take it of. As he is not allowed to wear rings at work, he wears it as a necklace. You can have all memories with you all the time. It's so easy to upload the pictures to the ring. Really fast delivery, it took just 5 days from placing my order to recieving the package in germany. And the packaging is also great. This little giftbox is beautiful. We will definitely order again!!! Thank you so much!!!!!!
