Every ring/band that leaves our shop, is made with love. Every ring is unique!

Construction of our rings:
All the pores will be filled with CA (Cyanoacrylate) so the ring can stand daily wear. We tested our own rings and they can stand water. They are waterproof but we always advise to not wear the ring when showering or swimming. From veneer to polished ring can take up to several days.

Ring size & custom:
If you order a Decazi ring it will be made by hand we don't have rings in stock. This way we guarantee that every ring is made by your wishes.
Make sure when you measure your fingers that the size is correct if you have troubles with sizing please let us now we can help you.

The resin we use are all created by us, keep in mind that a pattern will never be the same. If you have a custom order you can send us a message. We can create almost every colour combination.

We ship worldwide, to keep the cost low we send the rings in special envelopes fully protected.

Every order is handmade and unique, so for that we dont accept refunds. But we will find a proper solution to make you a happy customer.

Every ring is made to order ( unless other stated ) and may vary from the picture. a ring can never be exact copied as picture but the same style is asured.

We have most rings in stock but there is always a chance your size ran out of stock due to the high demand at this moment. when your ring is out of stock we will update the shipping dat automatically you will be notified when this happens. a ring that is out of stock will be restocked as soon as possible when we notice the out stock.

By purchasing this listing you agree to have read our policy.

All our products are handmade therefore a product cannot be made exactly like the listing images. Colors can vary but we try to make it as close as possible.

Products with genuine opal:
Keep in mind that the color for genuine opals can be very different, we cannot control this we rely on what we can get from the opal distributor. Blue opal listed can be yellow/red/purple/ or a mix of colors.
If you want a specific color please let us know.Information about our glows.

the glow in the pictures ( if there is glow added ) can vary. due to a couple factors the glow can be stronger or less strong. one of that factor is the amount of opal that is on top of the glow powder and the density of the opal.

If a powder is not in stock anymore ( due to the pandemic ) we will pick the closest one that is available.

Keep in mind that the glow is an add on and not the main feature of most rings.

If you want to make sure the correct color is added please let us know by sending a message.

    Information Dceazi Collect

    To fulfil your order, you must provide us with certain information (which you authorized Etsy to provide to me), such as your name, email address, postal address, payment information, and the details of the product that you’re ordering. You may also choose to provide me with additional personal information (for a custom order of jewellery, for example) if you contact me directly.

    2. The legal bases decazi relies on to collect, use, and share personal information
    The GDPR requires that you explain the legal bases you rely on to collect, use, and share personal information. The legal bases may include a buyer’s affirmative consent to receive marketing messages, compliance with legal obligations, and a seller’s use of the personal information in their legitimate interests (improving their services, for example). Throughout our privacy policy, Decazi should be as clear as possible about where and why they rely on these different legal bases.

    Why Decazi Needs Your Information and How We Use It

    We rely on a number of legal bases to collect, use, and share your information, including:

    as needed to provide our services, such as when we use your information to fulfil your order, settle disputes, or provide customer support;
    when you have provided your affirmative consent, which you may revoke at any time, such as by signing up for our mailing list;
    if necessary to comply with a legal obligation or court order or in connection with a legal claim, such as retaining information about your purchases if required by tax law; and
    as necessary for the purpose of our legitimate interests, if those legitimate interests are not overridden by your rights or interests, such as 1) providing and improving my services. We use your information to provide the services you requested and in our legitimate interest to improve our services, and 2) Compliance with the Etsy Seller Policy and Terms of Use. We use your information as necessary to comply with our obligations under the Etsy Seller Policy and Terms of Use.
    3. The third parties with whom Decazi shares personal information

    The GDPR requires that you disclose the details of any personal information you share with third parties. Decazi should explain to their buyers why, when, and with whom Decazi may share buyers’ personal information.

    Information Sharing and Disclosure

    Information about our customers is important to our business. Decazi shares your personal information for very limited reasons and in limited circumstances, as follows:

    Etsy. Decazi shares information with Etsy as necessary to provide services and comply with obligations under both the Etsy Seller Policy and Etsy Terms of Use.
    Service providers. Decazi engages certain trusted third parties to perform functions and provide services to their shop, such as delivery companies. Decazi will share your personal information with these third parties, but only to the extent necessary to perform these services.
    Business transfers. If Decazi sells or merges its business, Decazi may disclose your information as part of that transaction, only to the extent permitted by law.
    Compliance with laws. Decazi may collect, use, retain, and share your information if they have a good faith belief that it is reasonably necessary to (a) respond to legal process or to government requests; (b) enforce my agreements, terms and policies; (c) prevent, investigate, and address fraud and other illegal activity, security, or technical issues; or (d) protect the rights, property, and safety of my customers, or others.
    4. The length of time he keeps personal information

    The GDPR requires you to disclose the period of time during which you will store personal information. Decazi should consider how long he needs to retain information for business purposes and to comply with any legal or tax obligations, and keep in mind that data shouldn't be kept for any longer than necessary.

    Data Retention

    Decazi retains your personal information only for as long as necessary to provide you with my services and as described in their Privacy Policy. However, Decazi may also be required to retain this information to comply with their legal and regulatory obligations, resolve disputes, and to enforce my agreements. Decazi generally keeps your data for the following time period: 4 years.

    5. If transferring personal information outside of Europe, how the transfer will be handled

    GDPR requires you to disclose if you transfer personal information outside of the EU and the legal bases you rely on to do so, such as consent and contractual necessity. Decazi uses Google Cloud, which is Privacy Shield certified, so they should explain to its buyers that they rely on Privacy Shield as the legal basis for the transfer of their buyers’ personal information outside of the EU.

    Transfers of Personal Information Outside the EU

    Decazi may store and process your information through third-party hosting services in the US and other jurisdictions. As a result, Decazi may transfer your personal information to a jurisdiction with different data protection and government surveillance laws than your jurisdiction. If Decazi is deemed to transfer information about you outside of the EU, Decazi relies on Privacy Shield as the legal basis for the transfer, as Google Cloud is Privacy Shield certified.

    Your Rights

    If you reside in certain territories, including the EU, you have a number of rights in relation to your personal information. While some of these rights apply generally, certain rights apply only in certain limited cases. Decazi describes these rights below:

    Access. You may have the right to access and receive a copy of the personal information Decazi hold about you by contacting me using the contact information below.
    Change, restrict, delete. You may also have the right to change, restrict Decazi use of, or delete your personal information. Absent exceptional circumstances (like where Decazi is required to store data for legal reasons) Decazi will generally delete your personal information upon request.
    Object. You can object to (i) Decazi processing some of your information based on Decazi legitimate interests and (ii) receiving marketing messages from Decazi after providing your express consent to receive them. In such cases, Decazi will delete your personal information unless Decazi has compelling and legitimate grounds to continue using that information or if it is needed for legal reasons.
    Complain. If you reside in the EU and wish to raise a concern about Decazi use of your information (and without prejudice to any other rights you may have), you have the right to do so with your local data protection authority.
    How to Contact us:

    This listing has to be bought:
    (After 24 hours the engraving can't be changed)

    Our rings can be worn by men and women. The size and width can be adjusted as you wish, for the male a thicker ring and for the ladies a thinner ring. We can make the width 4mm-12mm depending on the design.
    (The processing time for a different width can be different, please send us a message to ask about the possibilities)
    So not only men's rings ;)

    We do accept exchanges.

    If you ordered the wrong size we charge a small fee of 20% of the price you paid for the ring + the shipping costs. ($48 USA this price can change)
    This is because tungsten cannot be resized. If the wrong size is sent and it's our fault (can simply be proven by images and a Mandrell ) a new ring will be sent free of charge.

    (Make sure before you print this chart that you scale it to 100% (not scale to fit/fit to page) otherwise the sizing is off)

    The service was perfect. We got an answer immediately. Our wishes were completely taken care of. In the pictures, the mosasaurus' teeth looked darker than they are. I would have found it a little darker to look more appealing. But it's nice to wear all the materials together. Thanks a lot for this work!!!

    Worked with me and followed the requests I had made. Specifically engraving old Norse Ruins into the ring as well as adding less chunks of Opal thus making slightly darker. Will probably take a picture of it in the spring time. Thank you for the hard work done on the ring. Oh if its very important to anyone, I only got a certificate for the Meteorite. Not the open or Bone, good luck.

    Très belle bague ( cadeau de Noël pour mon copain) qui est malheureusement 1 ou 2 taille trop grande pour lui. Vendu avec certification d'authenticité.

    Dude is #1

    It took about a month for it to arrive but it was totally worth it! The ring came exactly like how it looks in the pictures , or maybe even better because it is so shiny and precious!
