ZpětZpětWe provide free lifetime service for most of our precious metal, damascus steel, titanium and surgical steel jewellery. However, there are some exceptions where certain adjustments cannot be made for a particular piece of jewellery, so please consult with us in advance for any necessary adjustments.
Jewellery that is covered by free lifetime service is indicated in the product description. For some jewellery, lifetime service is not listed, however, it is possible to discuss restoration of appearance or other service. This is due to the specific characteristics of the particular piece of jewellery, which must be discussed individually.
All our jewellery can be cleaned in an ultrasonic cleaner. This will remove various kinds of dirt residues, such as dust, flour or grease, and your jewellery will be beautifully clean again. We also provide this service for free for those jewellery items where lifetime service is not directly stated.
The free service does not include postage. Usually the price is charged according to your choice of shipping method. It is free of charge for personal collection. Service time is usually 1-4 weeks depending on the current capacity of our workshops. Lifetime service does not replace the product warranty, which is 24 months from the date of purchase. The lifetime service may eventually be transferred to the new owner, as long as the proof of sale is retained.
For servicing jewellery with a stone or other adornment and for jewellery combining several materials, we always need to see the jewellery in advance in order to assess whether and in what extent servicing is possible.
Send the jewellery you want to have serviced to the address: Kredum Art, Jan Král, T.G. Masaryka 318, Ostroměř 507 52, Czech Republic. Please enclose a cover letter with a description of what you want to be done with the jewel. Do not forget to include your contacts (email, phone) and the number of the original order. You can also give us the jewellery in person at the above address.
The lifetime service mainly includes the removal of fine scratches and the restoration of the finish (gloss, matt, rough matt, darkening, restoration of the structure of the damascus steel damasteel).
People treat jewellery in different ways. Some people like their jewellery to shine like new and would like to keep that beauty for a long time. For some, the tarnish and patina that time leaves on the metal can be valuable and add to the jewellery's distinctive charm. Especially rings that you wear every day change over time. Just like life itself. It's like your life imprinting its fingerprints on your jewellery. Wedding rings then reflect your changing relationship. It is possible to think of it that way and accept the changing ring as part of your life.
Anyway, if you wish to have your jewelry almost like new, we are here for you. However, even here there are exceptions where this modification is not possible, or is more difficult to carry out, or comes at an extra cost. Please do not hesitate to contact us, we will be happy to discuss everything with you.
It is easier to renew finishes on jewellery without ornaments made of one single material. In the case of restoring darkening, in the case of jewellery with engraving, the inside of the engraving is blackened. If you do not mind, we can leave it like this. If you have a problem with it, we will sand down the engraving and restore it for a fee.
If the coating on the ring needs to be renewed, including rhodium, this is not included in the free service and a fee will be charged. If the customer wishes to have the coating inside the ring polished and there is engraving inside the ring, this engraving can be restored for a special fee.
If the ring is set with a stone, pearl or other adornment, the ring can only be restored to its shiny or matt finish. The restoration of the rough matt finish and the restoration of the darkening is only possible if the stone, pearl or other ornament is removed from the ring and re-set. This is possible for a fee by prior individual arrangement.
This also applies to jewellery that is made with a combination of several materials. For such jewellery, only the shine, matt or rough matt finish can be restored. Darkening cannot be restored.
For the servicing of rings with a stone or other adornment and for mixed metal jewellery, we always need to see the jewellery in advance to assess whether and to what extent servicing is possible. If this is the case, please send us a photo in advance to obchod@kredum.cz.
The material DAMASTEEL is a very specific material, which is particularly special because of its structure. This structure is basically renewable in the same form as when the jewel was new. Therefore, if the pattern on this jewellery becomes tarnished over time, it is possible to restore the pattern. This is possible without any problems, as long as there is no stones set in the ring or jewellery, or there is no other decoration. If the jewellery has a stone set in a gold or silver setting, it is usually possible to restore the structure. If the stone is set directly into the jewellery (diamond), the structure can only be restored in areas that are not closely adjacent to the stone. However, in both cases, additional darkening cannot be done.
In the case of jewellery combining damascus steel with another material, this is always a case for an individual assessment. Here it depends on the type of ring or jewellery. Contact us for more information. In general, in the case of combinations with gold and silver, the structure can be restored, but only light. Darkening restoration is not possible. If a stone is set into the ring, the restrictions above are applicable.
However, it is necessary to take into account that each renewal of the structure will slightly thin the jewel and this operation cannot be repeated forever. We therefore emphasise that the word "lifetime" means the lifetime of the jewellery. This applies not only to the renewal of the structure of damascus steel, but also to the renewal of darkening of surgical steel. back to top
It is obvious that the Lifetime Service also includes additional ring size adjustments. It depends on the type of ring whether and how much size adjustment can be made. The limitations on these adjustments apply especially to rings with stones and decorations and rings combining multiple materials. Therefore, always contact us in advance and we will be happy to discuss the adjustment with you.
In general, the simpler the ring, the easier the adjustment and it is always better to make rings larger than smaller. So if you can't decide between two sizes, it's better to choose the smaller one.
Rings can be enlarged by stretching and grinding the inner side. Grinding will make the ring thinner and if there is an engraving inside the ring, the engraving will be removed and it needs to be restored. There is a fee to restore the engraving when resizing. Rings can be made smaller by pressing or by inserting a silver inlay inside the ring.
Plain round rings without decorations made of one material can be resized without a great difficulty. Not only rings made of gold and silver can be enlarged and reduced, but also rings made of titanium, surgical steel and damasteel. If the material allows us, we can usually enlarge and reduce them by about 2 sizes.
However, there are also exceptions and limitations. If we resize down a "Klas" ring by pressing, the top peak in the middle of the ring may be compressed and thus partially flattened, which may affect its appearance. If we resize down the Rock ring by pressing, some of the flat areas on the surface may be dented and flattened. The enlargement and reduction of "Wood" type rings is limited. Sometimes this adjustment is only by half a number, depending on its dimensions. This ring cannot be stretched too much or its interior ground away; it is in danger of cracking. It also can't be pressed too much to avoid damaging the surface. Even the "Wood titanium" ring cannot be adjusted at all because of its properties.
The "Forever" ring can only be enlarged a little by grinding out the inner side. Making it bigger by stretching would straighten the wave. It is not possible to make this type of ring smaller at all, as the ring would be deformed by pressing.
Rings with precious stones and decorations can only be enlarged by cutting through the inner side, which is limited by the thickness of the ring. Usually only 1 or 2 sizes can be enlarged. Rings can only be made smaller by inserting a silver inlay. Here you have to take into account the increase in thickness of the ring (when reducing the ring by one size it is approx. 0.2 mm, when reducing it by two sizes it is approx. 0.4 mm). This silver insert is charged extra. These modifications remove or cover any engraving on the inside of the ring. It can be restored for a fee. It is always necessary to see these rings beforehand. Please send us a photo in advance for consideration.
Adjusting sizes for rings combining multiple materials is more complicated. It depends on the type and materials used and always needs to be assessed individually. Rings with yellow gold are best adjusted.
We always try to find some way to resize the ring but sometimes it is not possible. However, feel free to contact us and we will find a solution. back to top
We offer a 2 year guarantee on the setting of the stone. If the stone falls out within this two years time period, we assess the condition of the jewellery individually. If we find that the stone has fallen out or broken due to an impact with any object, we will set a new stone for a fee. If the crash has not been proven, we will set a new stone at our expense.
If the stone is dropped or broken after this period, we will set a new stone for a new fee. back to top
Beyond the free service, other adjustments to jewellery are possible. This may include narrowing rings, completing decorations, restoring or changing engraving, etc. Here the price of the modification will be calculated individually according to the complexity of the work and material.. back to top
For servicing jewellery with stones or other adornments, we always need to see the jewellery in advance to assess whether and to what extent servicing is possible. Please contact us in advance and send us a photo of the jewellery you wish to have serviced.
We guarantee the setting of the stone for 2 years.
If the stone falls out within this two-year period, we will assess the condition of the jewellery individually. If we find that the stone has fallen out or broken due to an object hitting it, we will set a new stone for a fee. If the crash has not been proven, we will set a new stone at our expense.
If the stone is dropped or broken after this period, we will fit a new stone at a charge.
For jewellery with a gemstone, pearl or other adornment, it is only possible to restore the shiny or matt finish, or in the case of damasteel, its light texture. It is not possible to restore the darkening of the damasteel structure. Restoring the darkening of a surgical steel or rough matt finish is only possible if the stone, pearl or other decoration is removed and re-set. This is possible for a fee.
In the case of damasteel jewellery, if a gemstone is set directly in the ring (diamond), it will only be possible to restore the design in areas that are not immediately surrounding the stone.
Rings with gemstones and decorations can only be enlarged by grinding the inside of the ring, which is limited by the thickness of the ring. This can usually be done by about 1 to 2 sizes. Rings can only be made smaller by inserting a silver inlay. However, the increase in thickness of the ring must be taken into account (when reducing the ring by 1 size it is approx. 0.2 mm, when reducing it by 2 sizes it is approx. 0.4 mm). This silver insert is for an extra charge.
These modifications will destroy any engraving on the inside. Its restoration is possible for a fee. back to top

If a stone is set in the ring, the restrictions above are applicable. Contact us for more information.
