    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.

    Looks great, chain isn’t durable.

    I love the necklace, and it looks great. The chain broke with very little resistance. The replacement process was simple, but not thrilled about the durability or prospect of losing my pendant in the future.



    Hi Jake, Thank you so much for this candid feedback! We will look into further improving the durability and strength of our chains. Hopefully, the replacement chain does not cause any issues. Howard PS It makes us happy to hear that you love the necklace and design!

    Beautiful Necklaces, App looks great, Great response from Developers

    THIS A REVIEW UPDATE (Used to be One Star) The necklace itself is elegant and beautiful. Android app. The recent app update (Aug. 26, 2022) looks great and works just as I expected. Previously, my photos used to not display any of the dates, titles, captions and additional notes when in view/slide mode as advertised in the video. However, after reaching out to the developers Khoi and Howard quickly responded. Howard preceded to apologize for any confusion on adversitments displaying an older version of the app and informed me of his plan to roll out the Aug. 26, 2021 update that would allow users to switch between the old and new versions of displaying memories! They also added some features like the option to transfer the current you are working onto the necklace instead of only being able to transfer all memories. Also, you can swipe the dates, titles, captions and additional notes display into and out of view. You can tell the developers are putting their heart and soul into the development of this product. It is a lovely ground breaking concept. And giving this necklace to someone would be a grand loving gesture, even if it is for yourself!

    Even better than I imagined it would be.

    I bought this necklace for my boyfriend’s birthday, I live in Scotland and it came so fast that it even arrived here before my other parcels that all come from the U.K. My boyfriend was really happy with his present and wears it all the time. I also had got in touch with Mementum, and they were so polite and helpful. I’m so pleased with my purchase.



    Hi Isla, Thank you so much for your kind words! We're happy that we were able to take good care of you. We are so grateful to have you as a customer. Whenever you need us, we’re here for you anytime. Have a wonderful day! Warm regards, Khoi

    Android app not displaying pictures as advertised

    Android app. My photos do not display and of the dates, titles, captions and additional notes when in view/slide mode as advertised in the video. They also don't have the nice rounded edges. Will an update be rolling out soon for the Android app otherwise I would like to return both necklaces even though I really like the concept, it was not properly executed. Side note: the necklaces themselves looks pretty as a regular piece of jewelry.



    Hi Tileena, Thank you for the feedback. I can see how that can be misleading, and I sincerely apologize for any miscommunication. What you saw in the video is an older version of our app. I will look into reviving elements of that experience and include them in our next release, which should be as early as this week. Regards, Howard

    She loved it. All her friends loved it (bonus win!) Thank you

    Fast shipping, easy setup, great instructions. I was even able to slip the simple app onto her phone & have a smooth surprise for her. Affordable & elegant. Well done. Great idea here.
