With Lumissoly, sustainability goes far beyond the product itself, it is our promise.

Our jewelry and technology are designed to be self-sustaining and to preserve your memories over time, regardless of the brand.

Technology

How does NFC jewelry work?

Your Lumissoly jewel is equipped with NFC technology and acts as a secure key to your personal memories.

When your smartphone comes into contact with your jewel, our app opens. Simply log in to upload your photos, videos, voice recordings, and much more. You can access these memories at any time by holding your smartphone close to the jewel. This way, your precious moments are always with you.

Does the jewel emit waves?

No, absolutely not. We use NFC technology, which is a passive technology: the NFC chip is activated only when you bring your smartphone close to the jewel.

Communication therefore takes place directly through your smartphone’s NFC reader when you bring it close to the jewel.

Your security and privacy are essential to us, and we use secure and discreet technologies to ensure your complete comfort. Bonus: it’s a standalone technology, it doesn’t need to be recharged.

How can I be sure that my personal data is secure?

Your memories are encrypted and stored in a decentralized manner. To date, there is no more secure way to protect your files, and we are the only ones offering this kind of technological solution.

Only your medallion and your security key can grant access to your files. We cannot view your private data, and no one else can access it without your physical medallion; unless they have been designated as a guardian. You own this storage and the files you keep there, and thus you are the sole decision-maker.

How much storage space do I have for my memories?

You have 20 memories (2GB) of storage space on the blockchain, prepaid for 60 years. You’re free to allocate this available space however you like among different file types (videos, photos, voice recordings, and PDFs), and you can track your usage as you add content.

If that’s not enough, you can purchase additional storage at any time, directly through the app. It will be available immediately.

What is the lifespan of an NFC chip?

An NFC chip has a lifespan of 20 to 30 years. It is embedded in the jewel like a watch battery and can therefore be replaced if necessary.

Since it emits no radio waves and poses no health risks, it is already widely used in everyday life and is completely safe.

How can you guarantee that memories will stand the test of time?

To ensure that memories last a lifetime, Lumissoly does not interfere with data access. Thanks to its decentralized storage, a three-key security system, and an encrypted puzzle, storage management is entirely in the customer’s hands. Customers are free to manage their storage, as well as modify it or extract files at any time.

Lumissoly connected jewelry was created to last forever.

Jewellery

Where is your jewelry made?

Our products are crafted in a certified French jewelry workshop. We use recycled silver and mother-of-pearl from French Polynesia, which is also hand-carved.

This partner was carefully selected after several trials to ensure that our products meet market standards. You will also find a hallmark on each of our medallions certifying the quality of its alloy.

What happens if I lose my jewel?

As your memories are stored in a decentralized manner, and need an extra key (password or security card) to be accessed, you can be reassured nobody will be able to access them, even if they have your jewel.

It is possible for you to keep accessing or even to extract your memories, with your security card and account. We also have the opportunity to reconnect a new jewel to your previous storage if you wish to do so.

Does the locket come with a chain?

Absolutely, the locket comes mounted on a 60-cm chain. You also have the option to choose a chain length between 45 cm and 60 cm. Just let us know your preference when you place your order.

What is a vermeil jewel?

Vermeil is a high-quality alloy consisting of a solid 925 sterling silver base plated with a layer of 18-karat gold of a minimum regulated thickness.

It offers the brilliance and elegance of gold, while ensuring durability, comfort, and affordability.

At Lumissoly, our vermeil jewelry is crafted from recycled 925 sterling silver and then plated with 18-karat gold (5 microns), in accordance with current standards.

How can I be sure my personal data is secure?

Your memories are encrypted and stored within a decentralized infrastructure. Today, this is one of the most secure ways to protect digital files and Lumissoly applies it to what matters most: your memories.
