Tips on resizing cobalt rings

 As discussed earlier, cobalt rings are resizable without any significant damages, especially if they do not contain intricate designs and precious stones. The jeweler heats the rings to extreme temperatures to enable him/her to increase or decrease its size. If your jeweler recommends cutting the ring and re-soldering it back together, it means they do not have the expertise to resize your cobalt ring. By cutting the ring, it will leave a mark to show it was cut, which is not very pleasing to the eye. Under no circumstances should your ring be cut, unless you want a substantial change in ring size.

It is advisable to resize your rings down or up by either half or one size. Your jeweler should have the ability to resize your cobalt ring by a maximum of two sizes up or down without any visible signs of alteration. It is usually not recommended to resize your ring more than two sizes up or down to prevent substantial damage. Therefore, if you think your finger size will increase or decrease dramatically in the future, it is best to opt for another ring type.

Resizing a cobalt ring requires a jeweler who has the experience and expertise of resizing such types of rings. Cobalt rings are incredibly strong, durable, and scratch-resistant. They are not as easy to resize palladium, gold, or platinum rings. As such, it is crucial to ascertain the resizing policy of your cobalt ring from your jeweler before purchasing it as it is likely that you will return the ring there for resizing purposes if necessary.

Basically, plain cobalt rings with only metal and no stone settings are usually the best rings to resize. If your cobalt ring has carved patterns, braided designs, or milgrains, it automatically becomes difficult to resize as it may distort the patterns or designs. Due to the fear of damaging your intricate ring design or pattern, many jewelers may refuse to resize your ring.

Fortunately, it is not impossible to resize cobalt rings with stone settings. The process only requires a jeweler with experience with such types of rings. A half-size change is usually not a big deal as it is possible without any signs of alterations on the ring. If you want the ring altered more than half a size, the result depends on the quality settings and the quantity of the precious stones on the ring, among many other factors.

If the ring has numerous precious stones, resizing it will require resetting all the stones and possibly changing the stone setting to accommodate the ring’s new size. The process is labor-intensive and often results in an uneven stone setting, making the ring look worse. As a result, jewelers tend not to offer resizing services in such circumstances.
