Production (Custom order?)
How long does the production take?
Almost all our products are made to order. The production time ranges from 7-21 working days. The timeline for our jewelry can vary depending on the complexity of the design and the specific piece you're interested in. It's important to note that custom designs may require an additional time. We prioritize quality over speed to ensure that your jewelry is a true work of art.

If you need a piece by a specific date or have a tight deadline, please let us know before placing your order. We will do our best to accommodate your request. Additional fees may apply for expedited services, and the availability of urgent order options may vary based on the specific design and materials. Contact us at info@mialis.czwith any other questions regarding processing time.
Do you have available jewelry in stock?
We often have some designs in inventory allowing us to take photos, measurements and use for appointments. These pieces are available for sale after the resizing. Please keep in mind that the resizing is not possible for every model, as some designs may have limitations in terms of adjustments. Please reach out to us at info@mialis.czif you have any specific questions about the Ready to ship jewelry.

Our products are made of only the finest quality materials. At Mialis we use recycled solid 14k and 18k gold along with platinum. Please remember that we don’t work with Sterling Silver. However sometimes we make the exceptions and accept custom designs in Silver.
What is the quality of your diamonds?
For our jewelry pieces we use high quality diamonds. D-G colors, VS-SI1 clarity. We can order the diamond according to your own requirements.
Is Jewelry at Mialis ethically sourced?
Our jewelry is responsibly handcrafted by professional jewelers in our workshop located in Prague, Czech Republic. All gemstones and diamonds come from legitimate and conflict free regions. We collaborate only with verified suppliers around the world.
What is a hallmark?
A hallmark is a symbol on the jewelry that indicates its authenticity and purity. Before hallmarking, the jewelry is marked with the manufacturer's or importer's responsibility mark.
Is it possible to design a custom piece
Absolutely! At Mialis we love to work with unique designs. Feel free to request customizations to any design featured on our website, or we can create a completely unique ring according to your preferences. Our colleagues are happy to help you with support and guidance.

Since a customized piece is crafted to your precise specifications, it is non-returnable and non-exchangeable. For our in-stock and listed items on the website, you can request returns and exchanges.
How do I know the price for the custom order?
Once we have the details regarding the setting, type of gold, and the specific stone you prefer, we can then calculate the final price.
Depending on how complicated the design is, and if it's a completely new model, we may ask you for a CAD design deposit. This deposit helps us create a preliminary design so we are on the same page about the piece. As a result it allows us to give you an estimated price. If you decide to go ahead with the project, we'll subtract the CAD deposit from the total price.
Custom order production process
Custom jewelry production can vary and may involve additional steps, depending on the design and materials used. The process may take several weeks or even months.

The process begins with a consultation. During our consultation we will discuss together your design ideas, preferences such as stones, material, ring size, and the budget range. We highly recommend that you provide us with sketches, photos, or other references.

The next step is CAD Design. After the deposit is paid we start creating a 3D model of your desired piece. Small changes such as stone shape or amount of prongs are possible to change for free. In case if you decide to change the whole setting it will be counted as a new 3D design for extra fee. In some cases we may offer a Wax Model or silver prototype to give the customer a physical preview of the piece. Once you confirm the final design we may require you to make a deposit to initiate the production process. The completed piece proceeds with a quality and assay office control inspection to ensure it meets the specified design and quality standards.
Can I see the stones you have in stock?
Some natural gemstones such as moss agate, rutile quartz or salt and pepper diamond are unique and one of a kind. You can choose the stone according to your preferences. For closer pictures or videos of the stones available in stock please contact us at will be happy to share it with you.

Could you set my own stone into the jewelry?
