You can easily measure the ring size using a measuring ringsizer that we will ship to you for free. The best way to know the correct ring size is to visit our showroom in Prague or any other local jewelry studio. However, there are situations when such a solution is not possible, for instance, in the case of engagement rings. If you don't know how to measure the ring size, read our tips!

Most of our jewelry can be created in all colors of 14K gold or platinum. However there are pieces in stock that are made with a unique gemstone and can’t be duplicated in different colors of gold. Please contact us at info@mialis.co.uk, we will check your request and let you know if the change is possible.

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. These fees can range from £100 to £150.

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.co.uk if 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 made jewelry designs in silver.

For our jewelry pieces we use high quality diamonds. D-G colors, VS-SI1 clarity. We can also order the diamond according to your own requirements.

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.

A hallmark is a symbol on a piece of jewelry that indicates its authenticity and purity. Before the hallmarking, the jewelry is marked with the responsible mark of the manufacturer or importer. Information about hallmarks, which certify the purity of precious metals, can be found on our page about hallmarks.
Only the Hallmark Assay of the Czech Republic can stamp jewelry. Mialiscz s.r.o. is registered here.

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.

Once we have the details regarding the setting, size, 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 (computer aided design) design deposit £150. 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 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 a 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 an extra fee. Custom 3D visualizations require an additional fee of £150.
In some cases we may offer a wax model or silver prototype to give the customer a physical preview of the piece for an extra fee.
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.

Some natural gemstones such as colorful sapphires, moss agate, rutile quartz or salt and pepper diamonds 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 info@mialis.co.uk. We will be happy to share it with you.

Definitely! For the matching band we need you to measure your engagement ring from all possible sides and share with us pictures with the ruler/tape. The rest process is the same as for the custom order (viz custom order process).

Yes, please provide us with the information, what exactly would you like to replace or change in the existing model. We gladly make the new calculations and share it with you via email. Changes made to orders after purchase may be subject to extended delivery.

Setting stones is one of the most complex disciplines in jewelry making. To ensure that the stone will be securely set in the jewelry, we only work with high-quality stones from trusted suppliers. As a result, you will receive a certificate of authenticity with each piece of jewelry.

Unfortunately, in our studio, we work only with alloys from verified suppliers, and if needed, we alloy our own materials that are verified and registered with the assay office. If we were to use unfamiliar materials, we wouldn't be able to guarantee their quality. Thank you for your understanding.
